House facade plastering technology. Facade fillers for outdoor use

Most of the residential and public buildings under construction are finished with a plaster mixture, which is called "wet". Facade filler - weather-resistant filler for outdoor use. It is used for the final leveling of walls before applying a decorative coating. Differs in special strength, moisture resistance, frost resistance. In this article we will tell you what the facade putty should be, how to apply and choose it correctly.

As mentioned above, facade putties must have certain qualities, namely high frost resistance. A high-quality putty should contain the following components:

• Plaster or cement.
• Plasticizer.
• Modifying additives.
• Mineral fillers.

Very often, when finishing the facade, putty is used with a high content of glue, soap, plaster and chalk. Depending on the type of work, different types of this material are selected, the most popular are: combined putty, facade cement, latex mixture, facade acrylic and others. A combined facade putty is considered a universal option, which is excellent for leveling the surface, in addition, it allows you to cover even very large flaws and flaws. The combined putty, even after many years, will not sprinkle, and will not exfoliate even in the cold season.

The shelf life of facade putties is limited to six months. Don't stock it up in advance!

The most popular types of facade fillers

To choose the right putty, you need to learn more about its composition and properties.

Latex putty is not suitable for facades

It is one of the most popular in its segment, suitable for any surfaces in the interior, but not suitable for facades. This material is sold in buckets of 25 kilograms. We will mention it only so that you know and do not get confused in the choice.

Glue putty

1. Possibility to mix with pigment formulations to change color. This will make it possible to do without painting the surface, and any mechanical damage on the walls will not be so noticeable.
2. Putty consumption per square meter. Consumption depends, as a rule, on the thickness of the laid layer and on the filler. The smaller the thickness, the more economical the material is.
3. The putty must be compatible with any.
4. The time period for the mixture to harden.
5. Plasticity of the material.

How to choose a winter facade putty

What are the main properties for winter facade putties - the ability to work at low temperatures and resistance to cracking during drying. As a winter, you can use both acrylic and cement putties. But on the manufacturer's packaging there must be a corresponding entry - "winter series". Of course, such putties will be a little more expensive than conventional ones, because they have added a special construction chemistry that improves adhesion at low temperatures.

Which facade putty is waterproof

The cement putty is waterproof. It is used not only for facades, but also for screed floors and for finishing bathtubs in the house. Therefore, it does not need additional polymers and hydrophobic substances, such as gypsum.

Gypsum putty for facades is not at all suitable and can only be used in interiors, and not in damp rooms. Of course, marketers and technologists have teamed up and found a way to apply it in wet rooms, adding those same water repellents to it.

Does the facade putty protect against fungus

Those facade putties, which include antistatic agents and antiseptics, protect. Better, of course, to treat the effect, and the cause. And prevent the formation of fungus on the facade. Mold on the facade is always the result of dampness, which for some reason appears and for some reason does not dry out. It is better to think in this direction in order to exclude the causes of the occurrence of the fungus.

Important! Remember that each subsequent layer in the wall structure should be more vapor permeable than the previous one. If this principle is violated, problems with the fungus cannot be avoided by any antiseptics. They simply cannot cope.

What kind of facade putty is suitable for painting

Any. Both acrylic and cement for your choice.

Which facade putty is better to lay down on the plaster

Any facade putty is suitable for working on a plaster facade. It will be easier to apply acrylic, but it is more expensive than cement. Acrylic is more elastic. Cement is more economical. It's up to you to choose.

What to do next after filling the walls of the facade

Painting, plastering, finishing with panels based on insulation or using the latest technology of a hinged ventilated facade. A curtain facade is cladding with siding, plastic or metal panels, porcelain stoneware, wood or stone imitation panels. In general, after finishing the facade, proceed with the exterior design.

How to properly putty the facade

Let's make a reservation right away, there are two ways to putty the facade: manual and machine. The machine is used to work with large volumes to increase the speed of work. For a private house, of course, this is irrelevant. By the time you get used to the device, the facade will be finished, and the material will take twice as much as with the manual method.

Therefore, it is advisable to apply the material on your own, using a spatula or a float. Regardless of the method of applying the material, first of all, the base must be prepared: the surface is cleaned of dirt, dust and oil stains, then the priming is performed, which is necessary to ensure the adhesion of the materials.

The ready putty material is mixed before work. If there are significant defects on the surface, they must first be eliminated by filling cracks and cracks with putty. After the patches are completely dry, a continuous layer of material can be applied. Multiple coats should be applied if necessary. It is recommended to sand the finished surface to achieve an excellent result.

Advice. Do not putty the facade in high humidity or in hot weather, when the surface is very hot - this greatly reduces the quality of the finish. Because the putty takes a certain time to dry.

Front putty consumption per 1m2

1. Starting and finishing putty.
2. Universal putty.

Consumption per 1m2 of starting and finishing putty

Starting putty is needed to seal cracks, level out small drops. Its consumption cannot be accurately calculated, since it is necessary to build on the state of the wall. But to grout a medium crack, you will need a layer of approximately 3-4 mm per square meter. It may not be necessary to cover all the walls with starting putty, so it makes sense to estimate the area of ​​the putty.

To cover one square meter with a 4 mm layer of starter filler, you will need four kilograms of dry mix. Usually dry mix comes in 20 kg bags.

The consumption of the finishing putty per square meter is less than the starting one. Largely due to preliminary priming of the surface. You can navigate by 1 mm.

To cover one square meter with 1 mm of finishing filler, you will need 1.2 kg of dry mix.

Consumption per 1 m2 of universal filler

The declared consumption of universal putty by manufacturers is lower than the combination of starting and finishing putty separately. Usually, it is 1.5 kg per square meter for a layer of 1 mm. Manufacturers always indicate consumption on the package.

How many mm thick layer you need, everything will depend on the condition of the surface to be coated. Let's focus on the 2mm middle layer.

To cover one square meter with 2 mm of universal filler, you will need 3 kg of dry mix.

It is justified to use the universal putty on more or less smooth surfaces that are not prone to cracks.

Stages of work

It is recommended to finish the facade after foundation shrinkage. As a rule, this process takes about a year. Wall processing requires some effort and effort, you must be fully prepared for the fact that you will have to do at least two layers of mortar in order to get the desired result.

It will be impossible to manage with one layer, even a qualified specialist will not be able to cope with such a task. The best temperature for outdoor work is from 9 to 20 ° C, the permissible air humidity should not exceed 80%.

The process of applying the putty is as follows:

1. The surface is cleaned of excess dirt and old finishes.
2. A primer is placed on the cleaned surface; it must dry before starting the further operation. It is better to prime the surface in two layers.
3. Next, depressions, dents, and cracks are removed. After which the material is allowed to dry out.
4. The putty is applied evenly to the walls, and then carefully leveled. As improvised means, it is better to use two metal spatulas of different sizes and a construction float. It is important to note that the facade material must be used in its pure form; it must not be mixed with paint or other additives.
5. After the first layer of putty has dried, it must be primed in order to improve adhesion to other layers.
6. Apply the starter filler layer by layer until the façade surface is completely straightened out. Each layer is applied only after the previous one has dried.
7. At the last stage, a finishing putty is laid on top of the base material.

Expert experience

According to many construction companies, the best option for building facades is one that contains cement. Such material is quite easily applied to the surface of the walls and has high strength after drying. If you are going to repair the facade, then you need to understand that each subsequent layer should be more vapor-proof than the previous one. Otherwise, fungus and mold cannot be avoided. In order not to bother you too much with the selection of each layer, choose all elements from one manufacturer. This ensures that you adhere to the principle of vapor permeability when decorating the facade. So you can completely protect yourself from incompatibility of materials.

Happy finishing! Share your comments and experience in facade putty.

Both new and old houses require exterior decoration, and today the wet method of facade decoration is increasingly used. In order to level the walls, close up the joints between the slabs or bricks, and then apply the finishing decor with plaster or tiles, use a facade putty. The article will tell you about the types of this finishing material and the technology of working with it.

Aligning walls is one of the most time consuming and important processes in facade decoration. Without it, many other work on the design of the external appearance of the house becomes simply impossible. For example, plastering of a surface can only be done on perfectly flat walls, and laying and gluing insulation on an unprepared base is impossible.

The words putty or putty come from the German word "Spachtel" - a spatula, the use of both is quite acceptable, so in the further narration you can meet both. In addition to leveling, the putty performs another important function - sealing potholes and cracks in the wall. It was originally used for just that.

Brick wall alignment

Requirements for facade filler material

Based on the purpose of the facade putty, a number of requirements are imposed on it, which must be taken into account when purchasing.

• Plastic. This property is characteristic of a quality solution. If the material does not possess it, then there is a serious risk of cracking of the coating and its destruction from atmospheric vibrations.
• Water vapor permeability. The most important property of all types of facade finishing materials should also be in the putty. If it is absent, then fumes will accumulate under the leveling layer and destroy it from the inside.
• Moisture resistance. The ability to repel atmospheric moisture and not let it pass inside protects not only the putty itself, but also the facade of the house. Water can remain in the pores, and when it freezes, expand it and destroy it.
• Frost resistance. Cracking from frost or seasonal temperature differences can also befall the main wall covering, therefore frost resistance is a very important quality for a putty mortar.

Materials and tools for puttying

Classification of putties by purpose

All putties for facade work are divided into two types: starting and finishing. Usually both are required. Before buying, ask about the purpose and type of material, so as not to buy unnecessary ones. In addition, you need to decide which putty you need more and in what quantity.

Starting

The structure of this composition should be coarse-grained and have increased strength and high adhesiveness. It smooths out the main unevenness of the wall, repairs structural cracks and potholes in the facade that require repair. It is often used to eliminate unevenness in masonry or defects in concrete walls. The composition can be applied in a rather thick layer - up to 4 mm. For strength, particles of marble dust and lime are often added to the starting mixture. They give it the necessary elasticity and adhesion to the building surface. Most often, cement compositions are used for the starting layer, and polymer binders give elasticity to the putty.

Attention! When purchasing a starter putty mixture, make sure that it is intended for facades. It is unacceptable to use compounds for internal works for external walls.

Starter putty

Finishing

The final putty coat must be plastic, smooth, waterproof, have good adhesion and strength. Most often, a mixture based on acrylic or silicate binders is used - they are more consistent with the goal of creating a smooth and uniform layer. Finishing putty is used to level the surface, and therefore the particles of which it consists must be small.

The finely dispersed structure allows you to create a perfectly flat base for the future decorative coating. Experienced finishers recommend applying the finishing filler in several steps with a layer of about 3 mm. Do not use for leveling coat mixtures that are difficult to mix with colors. If in the future you are going to finish the walls with decorative plaster or paint, then it is better to tint the finishing putty in the appropriate shade, otherwise it may shine through the main finish.

Types of front fillers on the basis

The building materials market offers a wide selection of putty compounds. Manufacturers, prices, mix types can confuse any inexperienced finisher. Let's try to understand the main types.

Reinforcing mesh under cement

Cement

Such fillers are considered the best for applying a starter coat, for sealing cracks and potholes in the wall. Cement-based mixtures usually consist of cement, lime flour with fractions from 0.2 mm, quartz sand and marble dust. To improve the characteristics, chemical additives are added to it. The surface covered with the cement-based starter filler looks perfectly flat, but rather rough due to the coarse-grained structure of the material. The finishing cement putty has a fine dispersion structure and comes in several colors: gray, beige and yellow. White cement putty is practically not found now. Since its bleaching requires expensive formulations, which increase the cost of the finished mixture. It is available in the form of powders and ready-made mixtures in buckets. There are also disadvantages to a liquid material.

• Severe shrinkage of the dried mixture must be taken into account when filling cracks.
• If the liquid cement composition is applied in a thick layer, then the probability of cracking is very high.

In order to prevent the destruction of the cement coating, a reinforcing mesh is applied during operation.

The advantages of cement compositions cover their minor disadvantages.

• Ease of use allows even an inexperienced finisher to work with it.
• Cement is a durable material and guarantees high frost resistance, density and weather resistance.
• It has an affordable price, and therefore is very suitable for processing large surfaces, which is typical for building facades.

Important! Never mix cement putty with varnishes, paints and adhesives, so that it does not lose its properties.

Cement Finish Grit

When purchasing cementitious mortars, pay attention to the cement grade, compressive strength and adhesion level.

Gypsum

Plastering with gypsum mixture is one of the easiest ways to putty the surface of the facade. It is very easy to work with gypsum, because it has a plastic, lightweight structure and lends itself well to leveling. Plastic allows not only to easily align, but also to accurately form corners and perform other curly work on the facade of the building. The positive aspects include good vapor permeability, frost resistance, smoothness, and easy staining. The absence of shrinkage allows you to make the layer as thick as you like and apply it in one go.

But there are also downsides. If you live in rainy, humid areas, then it is better to use a minimum of gypsum, as it absorbs moisture quite well and can be destroyed under its influence. On the other hand, the gypsum mixture dries very quickly, so it is not recommended to work with it under the scorching sun.

When purchasing gypsum plaster, pay attention to the manufacturer. Better to take proven brands. So you will protect yourself from quick damage to the facade and get confidence that the mineral additives contained in the composition are of high quality, which means that the coating will last longer.

You can apply gypsum plaster in one layer

Acrylic

These finishing materials are starting and finishing materials. Possessing all the necessary properties, acrylic mixtures can and should be used for facade work. They are sold ready-made, which makes them even easier to use. Facade acrylic putty has good adhesive properties, but it is applied to a previously primed surface, since the putty layer is quite thin. The only thing missing is acrylic mixes - the higher price compared to previous products does not allow using it on large areas as a starting layer. Most often it is used for finishing.

Latex and acrylate

These types of putty materials are designed for extreme conditions and therefore are used for outdoor work. They are even more moisture and frost resistant than conventional acrylic. Its durability and plasticity has earned recognition from builders and fitters around the world. Latex and acrylate do not crack or shrink when dry. High adhesive properties make it possible to further strengthen the protection of the walls of buildings and make the bond with the subsequent decorative coating the most durable. Latex mixtures come in a wide variety of colors and therefore do not require additional staining. The thinnest layer of this composition forms the perfect finish. There are such starting and finishing plasters, but too high a price is their main drawback.

Colored latex putties

How to choose the right filler for the facade

The characteristics of the putty and the knowledge of which material is better to apply in certain cases will help you not to make a mistake with the choice.

• When insulating the facade with polystyrene foam, polystyrene foam or polyurethane foam, it is better to use latex and acrylic textures. Use the same types of finishing mixtures with poor wall permeability, for example, on concrete or metal.
• If you live in cold zones, where frost is a frequent visitor, then use a special frost-resistant putty.
• Do not use oil products for facade work, but if you did buy them, then remember that you will only have to paint them with oil paint, since other paints will not fall on the drying oil plaster. But if your house is made of wood, then an oil-based facade putty is a good choice.
• Try not to use materials from different manufacturers, price categories and types. If you started working alone, try to finish the process of filling the walls with the same compound. Remember that materials may not be combined with each other! It is for this reason that it is better to immediately calculate the amount of the product and assess your financial capabilities.
• When calculating the amount of material, proceed from the thickness of the layer you need to apply. The thinner the coating, the less putty is consumed.

Dry polymer-cement plaster mixture

Main manufacturers and prices

• One of the most recognized manufacturers on the building materials market is Ceresit. Polymer-cement plasters from this manufacturer are distinguished not only by high quality, but also by low cost. They are made of a cement-sand mixture with the addition of polymer additives and synthetic fibers for plasticity. These mixtures are distinguished by high vapor permeability, fire safety, long shelf life, and economy. In addition, Ceresit putties differ from many in color. These are white mixtures, which is rare among cement compositions.
• Synthetic plasters of this company are produced ready-made and meet the requirements of facade materials. Acrylic, based on acrylic resins, polymer silicate and polymer silicone compounds are used for finishing walls. They are distinguished by increased resistance to deformation, moisture resistant and elastic. You can study the properties of acrylic materials from the photo in the table.
• Knauf, a global manufacturer of building materials, has a strong position in the sale of plaster and putty compounds. It produces finishing cement mixtures in dry form, which significantly saves money on facade finishing. A package of 25 kg of multi-finishing cement mixture costs about 600 rubles.

Characteristics of Ceresit acrylic filler materials

The company "Prospectors" has shown itself to be excellent in the domestic market. It offers various facade mixes at low prices with good quality. Weber Vetonit finishing putties have been in demand for many years. This dry polymer product for facade work has a low cost - about 600 rubles.

Starting putty application technology

The easiest and most popular way is to plaster the lighthouses.

• We begin to plaster the wall. To do this, take a trowel in our right hand, and in the left solution and with a sharp movement we throw the solution onto the wall. After that, with a scraper or grater, rub the stacking mixture over the surface.

Grouting mixture

The whole process is well shown in the video. Pay attention to the technique of throwing the mortar onto the wall.

Plastering walls on lighthouses

Finishing process with finishing putty

Finishing technology with finishing filler resembles working with a starting solution. After the starting layer has completely dried, apply the finishing layer in the same way: using a trowel, pour the solution onto the wall and rub. The only difference is that the thickness of the coating is minimal, and the rubbing must be very careful, since this process is followed by the application of a decorative coating. You can apply several methods of grouting putty: round and ramp.

When finishing, it is important not to interrupt the process of processing the wall. Try to calculate the time for finishing entire sections of the facade.

Methods of grouting putty

As you can see, the facade putty can be applied with your own hands, for this you only need a little patience. By preparing the walls for decorative finishing yourself, you significantly save money, which you can spend on better material.

Facade putty for external construction work, as a material, in addition to the leveling function, protects the external walls of the structure from the negative effects of weather conditions - moisture, frost. It comes in several forms. Mixtures with a paste consistency are applied immediately after purchase, as they are already ready to use. When buying dry powder, you will have to work hard and prepare the mixture yourself at home.

Outdoor work

The finished material is packed in buckets. Despite the ease of use of such a putty, the transportation process is not as convenient as in the case of the dry version.

Facade putty and ready-made compound of various consistency. It depends on the manufacturer and the purpose of the material.

The following compositions are distinguished by classification:

1. Starter - the material is treated as leveling or base material.
2. Finishing - the composition used at the last stage of outdoor work. The material is fine-grained with a liquid consistency. Unlike the starter version, this facade putty is not so strong, but the end result is of high quality. This is possible due to the advantageous properties - easy and thin application (layer of 0.4 mm), flexibility to processing (grinding).
3. Universal - the material includes the advantages of the two previous options, is not used for external work on the processing of facades.
4. Decorative - the composition is used to form objects for decorative purposes or to create stucco elements that are attached to the building from the outside.
5. Facade wood putty - used for external walls of a building made of wood in order to level the surface to a smooth state. In addition, the mixture is used as a protection for wood that is vulnerable to weather conditions. It is suitable if the paneling is made of wood.

Another option for facade putty

Distinguish between products based on cement, which is well adjacent to moisture and low temperatures, or polymer.

The group of polymeric materials includes acrylic / latex blends.

Advantages of acrylic-based material:

1. Convenient use.
2. Ease of use.
3. Fast drying time, no cracking or shrinkage.
4. Do not add water to achieve the desired consistency.

Characteristics of stable outdoor mixes

For outdoor use, special mix options are provided. They show increased resistance to weather conditions and have corresponding technical characteristics.

Facade plaster with waterproof properties is a vivid example of a practical approach to the choice of building materials.

She has the following advantages:

1. Reliable protection against moisture - evaporation, condensation, or heavy rain will not seriously damage your building.
2. Ease of application, ease of distribution over the surface.
3. Application does not take much time, which allows you not to delay the preparation of the walls.
4. It is also used indoors, which helps out during repairs in saunas, bathrooms, industrial premises.

The cost is low, and taking into account the advantages, such a composition can be safely called convenient and practical. It is recommended to use it at the preparatory stage before painting.

A video review will tell you how to work with putty compounds when processing facades:

Another option is popular among consumers - frost-resistant putty. It is characterized by easy application, well perceives the proximity of various types of plaster. Facade mixture with resistance to low temperatures is most often used to fill cracks and eliminate other façade defects.

The composition is considered universal. The work is not limited to specific weather conditions. Frost-resistant putty is both practical and reliable. The cost is more expensive than the waterproof mixture, but the benefits are much greater.

On the modern market, there are materials with heat-resistant characteristics.

Appointment of facade fillers

As mentioned above, facade putty is used not only for leveling the surface during construction. There are a couple more advantages that should not be hidden:

• it performs protective functions against the harmful effects of weather factors and any mechanical damage;
• acts as a soundproofing and heat-insulating material.

Composition and properties

The main properties of facade finishing putties are:

• high adhesive properties;
• plastic;
• moisture resistance;
• frost resistance;
• resistance to cracking and fading;
• resistance to any temperature extremes;
• excellent compatibility with any paint and varnish materials.

As part of the finish, there are several components that provide all of the listed properties, first of all, it is cement, gypsum and chalk, then there are mineral, marble and modifying additives and fillers. as well as plasticizers.

Cooking technology

If you have purchased a dry mix for finishing external surfaces, then you will have to dilute it. If you have never done this, then first of all, study the instructions on the packaging, usually manufacturers indicate not only the guidance process but also the required proportions.

The standard aiming scheme looks like this:

• The dry mixture is poured into prepared water and gently stirred. The amount of water and mixture is taken strictly in proportion.
• The solution is mixed in several ways, manually, which is quite laborious and time-consuming, or with a drill, in which case the finished mixture will be more homogeneous.
• After mixing, it is kept for 5 minutes, and mixing is performed again.

The calculation of the required amount is carried out empirically, first a small portion of the solution is induced and the area that you have processed is measured, according to this, the required volume of the finishing mixture is calculated.

Facade putty - a building mixture designed to give the outer surface of the building - the facade - ideal smoothness, which is necessary for high-quality decorative finishing.

This material is often called a little differently - putty, but both terms mean the same concept. They come from the German word Spachtel, which is translated into Russian as "scapula".

Putty for outdoor work is used almost everywhere, since it is impossible to lay the walls of a building perfectly even.

In addition to leveling the surface of the walls, the task of facade putties is to protect them from external influences. You can buy this material both ready-made (pasty mixture) and in the form of a dry powder. In the latter case, the preparation of the putty has to be done by hand.

Classification of putties by purpose

All types of facade putties are finely dispersed materials, but depending on the purpose, they can consist of fractions of different sizes.

In addition, ready-to-use solutions for different applications may differ in consistency. On this basis, all mixtures for facade work are divided into several groups:

1. Starting (base or leveling) putty.
2. Finishing putty. The finishing facade putty is a mixture with a finer grain than the starting one. In addition, the finished solution should have a more liquid consistency. Finishing putties are used for the final leveling of the walls, giving them a perfectly smooth and even surface, which is extremely important for the subsequent decorative finishing of the facade of the house. The mixture is applied in a thin layer not exceeding 4 mm in thickness. In terms of strength, the facade putty for finishing works is inferior to the starting one, but it is very well sanded and is more pliable.
3. Universal putty. This finishing material combines the advantages of the 2 above-described varieties, but it is not used for facade putty.
4. Decorative putty. The creation of textured decorative elements or stucco molding on the outside of the building is performed using this type of facade putty.
5. Wood putty. It is used for smoothing and weather protection of wooden walls or walls with wood sheathing.

The technical characteristics of the facade putties are due to the intensity of the atmospheric effects on the exterior surfaces of the house.

They must have vapor permeability, moisture resistance, frost resistance, elasticity (elastic putty tolerates wall shrinkage and changes in their dimensions due to temperature changes).

On a façade leveled with a putty, paint, tiles, enamel, mosaics, etc. can be applied.

Types of putties on the basis

Since all types of facade putties are assigned the functions of a protective barrier, they must have a sufficiently reliable base. For this purpose, cement or polymer components are used. Let's consider both options in more detail:

Facade cement putty is characterized by high resistance to moisture and low temperatures.

In addition, it has good strength, so it almost never cracks when it dries. For the manufacture of cement-based starting putty mixtures, quartz sand is used, crushed to 0.5-0.6 mm. The composition of the finishing facade putty may include the following components:

• limestone flour with granule sizes up to 0.2 mm;
• ground quartz sand (marshalite);
• marble dust (microcalcite).

To improve the technical characteristics of this finishing material, its composition is enriched with chemical additives. Cement putty for facade surfaces can be beige, yellowish or gray.

White cement putty is not currently produced, since expensive bleaching agents have to be used for its production.

For home craftsmen who want to finish the walls of the house with their own hands, before buying a cement-based putty, the masters recommend paying attention to the following aspects:

• cement grade;
• compressive strength;
• the level of adhesion with the material to be finished.

Polymer based putties

Polymer binders serve as the basis for a variety of facade fillers. All of them can be roughly divided into two large groups:

1. Acrylic fillers. All brands of acrylic fillers are made on the basis of acrylate-siloxane mixtures. They are excellent for both basic and finishing of external surfaces of buildings and structures. Acrylic-based mixtures do not need to be diluted with water, they are easy to apply and work well. After laying, the material is leveled to a thin layer approximately 2 mm thick.
2. Latex putties. This type of polymer putty is not used for facade finishing.

All putties for outdoor use, which have a polymer base, have a number of advantages:

• strength;
• durability;
• plastic;
• fast adhesion;
• no shrinkage;
• lack of smell.

There are also special mixtures used, for example, for finishing polyurethane.

Preparation of the solution

Modern manufacturers of building materials practice 2 forms of supplying putties for all types of work: in the form of a ready-made mixture and dry powder.

In the first case, the material is supplied in hermetically sealed plastic buckets, in the second - in paper or plastic bags of various sizes.

Before finishing work, a solution must be prepared from a powdered putty.

The preparation process is quite simple: the dry mixture is diluted with water (the consumption of water and powder must correspond to the recipe given on the package), then thoroughly mix with a drill with a special nozzle until a creamy consistency and let it brew for several minutes.

The volume of one portion of the mixture should not be too large, since most brands of facade putties retain their working qualities for only three hours.

In order to determine the optimal amount of the prepared solution, the master should start working with a small portion, having determined his own hourly productivity in terms of area and the consumption of putty per 1 m2 of the treated surface.

Completion of finishing works

It is recommended to start finishing work on the facade of the building after the foundation has shrunk. On average, this process takes about a year. Wall decoration requires effort and effort, you should be prepared for the fact that for satisfactory quality you will need at least 2 layers of base solution.

Even the most experienced and qualified master will not be able to do with just 1 layer. The optimum air temperature for outdoor finishing work is 5-20 ° C, the maximum permissible relative humidity is 80%.

Operations are performed in the following sequence:

1. The surface of the wall is cleaned of dust, dirt, remnants of old finishes and oil stains. If there are places with cracked plaster coating, it must also be removed.
2. A deep penetration primer is applied to the cleaned wall, and must be completely dry before starting the next operation.
3. On the surface to be treated with a starting putty, separate defects are sealed: depressions, cracks, dents. The material is then allowed to dry.
4. A portion of the putty is applied to a section of the wall, and then leveled. The best tools are a construction trowel and 2 metal spatulas. It is important to note that the facade putty must be applied in its pure form; it cannot be mixed with paint, glue or other dry mixtures.
5. After drying, the first layer of putty is primed in order to improve the adhesion of subsequent layers to it.
6. The starting putty is applied in layers until the facade surface is completely leveled. The maximum thickness of individual layers is 4 mm. Each subsequent layer is applied only after the previous one has dried. Average consumption of starting putty per 1m2 is 11-15 liters.
7. At the final stage, a finishing layer is laid and leveled on top of the base putty, which should be sanded after drying. Approximate consumption of finishing putty for 1m2 is 4 liters.

The putty must not be applied to hot surfaces. During the finishing work, it should not be exposed to direct sunlight, rain or splashes.

In order to protect the freshly applied solution from atmospheric moisture, the finished facade surface is covered with plastic wrap until it dries completely.

All putties of this brand are frost-resistant.

The price of a standard package is 300-350 rubles.

Vetonit (Finland)

Polymer putties for outdoor work of this brand have proven themselves well, therefore they are in rather high demand in the domestic construction market.

Mixes for rough work consist of granules up to 0.3 mm in size, decorative white putty - from 0.5 to 1.5 mm. The solutions are very easy to prepare.

They do not lose their working qualities for a long time, which allows the foreman to carry out the work carefully and without unnecessary haste. The polymer filler ensures the minimum consumption of the finishing material, even with a large number of defects on the treated surface.

For climatic conditions with a high content of atmospheric moisture, the manufacturer recommends using an acrylic putty. This material is characterized by good adhesion not only to concrete, but also to wood substrates.

White acrylic putty has elasticity combined with good strength, it is very convenient for sealing large defects, seams and joints.

Among the advantages of the material is high durability and odorlessness. Thanks to the polymer base, it is very easy to achieve an even layer distribution when using Vetonit putties.

The price of a package weighing 5 kg is 250-270 rubles.

"Prospectors"

A very popular brand of putty in our country, the attractive side of which is a successful combination of good quality and affordable cost.

Great for people with insufficient experience who want to learn how to do facade decoration with their own hands. Putty of the Prospector brand can be used both for its intended purpose and as a budget alternative to facade paint (paint of any color can be added to the ready-made solution, which has a beige tint).

At the same time, painting the facade with a composition based on this putty is 10 times cheaper than the same operation using the most inexpensive facade paint.

The approximate price of a standard package is in the range of 200-300 rubles.

In addition to those listed, the following brands can be noted:

• Bolars (the price of a standard package is 300-350 rubles);
• Volma (buying a 25-kg bag will cost 400 rubles);
• "Glims" (the average price of a 20 kg package is 400 rubles).

Now you can easily choose a filler, depending on the purpose and conditions of the repair.

Building a house involves the use of many materials. Before the finishing of the facades of buildings, one cannot do without leveling the walls and sealing cracks, for this, putty is used. It is often confused with plaster, but these are two different compositions.

The putty is a powdery or liquid mixture that is capable of smoothing out small irregularities in the surface and giving it an aesthetic appearance. It is applied to surfaces previously treated with a primer. For exterior work, facade putties are used. A distinctive feature of their solutions is their resistance to cracking.

What are the compositions of the material and what are they for?

Strength and performance characteristics depend on its formulation. There are several types of this material, but each of them has common components:

• mineral fillers;
• plasticizers;
• cement or gypsum;
• modifying additives.

The variety of the latter will determine the plasticity of the solution, adhesion to the treated surface, and resistance to an external aggressive environment. Often, adhesives, laundry soap, varnishes, drying oil, chalk and gypsum are introduced into the putty solution as additives. They are selected depending on the operating conditions of the solution.

You can find out how long the putty dries in this article.

Facade putty is used not only for leveling the outer walls, but also on the inside of them. Before applying it, the surface must be cleaned of dust and primed. Today, there are mixtures on sale in which a primer is already present, they can be immediately putty on the surface without preliminary preparation. The composition is applied in a multi-layer method, allowing the previous layer of putty to dry. Then, after the last layer has dried, it is treated with coarse sandpaper or a metal brush.

On the video - facade putty for outdoor use:

What wood putty looks like for outdoor use can be seen by reading this article.

It can be basic and finishing. The first one is used as the basis for the subsequent application of building materials, and the finishing one is used at the final stage. It is most commonly used to prepare exterior walls for subsequent painting. It is waterproof and frost-resistant.

Water-repellent putty prevents the appearance of condensation on the walls resulting from rain and vapors hitting the surface. Its advantages are:

• simplicity and speed of application;
• uniformity of distribution;
• protection of concrete structures from moisture;
• compatibility with various types of plaster.

A frost-resistant version of concrete putty is used to seal cracks and chips on the surface of buildings. It makes the building resistant to low temperatures. The opposite is the heat resistant putty, which is also popular.

How the finishing putty is applied under the wallpaper is indicated in the article.

Varieties by composition

Depending on which component is the main one, the following types are distinguished:

• cement;
• acrylic;
• latex;
• silicate;
• oil and glue;
• gypsum;
• silicone.

Cement

Cement putty used for concrete structures if they have deep cracks... This mixture is sold dry, diluted with water before use. Keep it away from moisture. It is of three types:

• starting;
• universal;
• finishing.

The starting composition includes quartz sand, and the finishing composition is made from marble dust and marshalite. Special additives improve their properties.

What a putty looks like for a wooden floor is indicated in this article.

The advantage of these materials is:

• resistance to temperature extremes;
• affordable cost;
• ease of work with them.

• shrinkage;
• over time, cracks may appear on their surface.

Acrylic

Acrylic putty is used not only for leveling walls, but also for decorating them. It comes in liquid form and can be applied immediately to walls. It can be applied to absolutely any surface. There are finishing and leveling.

Here is how to apply the finishing putty under the wallpaper.

Due to the plastic structure, acrylic compounds are well applied and do not flake off during operation. The admissible layer thickness of such a putty is 1-3 mm. Before applying it, the surface must be prepared and primed.

Pros:

• moisture resistance of the material;
• elasticity;
• high strength;
• ease of application.

The difference between gypsum plaster and putty can be found in this article.

Minuses:

• unable to repair deep cracks in one go;
• grinding of its frozen surface must be carried out in a respirator.

Latex

Latex (acrylate) putty is suitable for application to external walls due to its improved moisture and frost resistance characteristics. Produced in pasty form.

Pros:

• easy application;
• plastic;
• high protective characteristics;
• durability.

How latex wall putty is used is indicated in this article.

Minus:

• high price.

Silicate

Silicate fillers are a mineral type of facade mortar. They are based on liquid glass. The formulations can be purchased in the form of ready-made masses. They are distinguished by high vapor permeability, therefore, this type of putty is used for walls made of shell rock and aerated concrete. This type protects the material from moisture and dust accumulations, as it has neutral electrostaticity.

Pros:

• they are used on walls where other putties cannot be used due to the low rate of steam permeability;
• perfectly protect the surface from moisture.

Minus:

• their surface often suffers from cracks.

How the finishing putty for painting is used and what is its price is indicated in this article.

Oil and glue

Oil-based adhesives are the oldest mortars used for wall cladding. They protect the surface from external aggressive factors, protect it from loss of performance. Due to their dense composition, during their application, a situation with a heterogeneity of the layer may arise, pieces of solution often fall off the walls. This is due to the high specific gravity of the mixture compared to other putties.

A plus:

• high protective properties;
• low price.

Minus:

• high weight and density;
• more often they are used to treat floors than walls.

Gypsum

Gypsum fillers are used for almost all surfaces and conditions. Their properties depend on the type of polymer additives. For example, polystyrene increases the frost resistance of the compound, and latex helps it resist moisture. It does not shrink, so it does not crack when it dries. Available in powder and liquid form, the latter is more expensive.

Pros:

• high technical characteristics;
• wide range of applications;
• durability;
• plasticity, it is easy to handle places with deep cracks with it;
• affordable price.

Minus:

• it is better not to use it in pure form, it is necessary to buy a solution in which additives are present.

Silicone

Silicone putties are the most stable and expensive solutions. They are flexible, have a high vapor permeability and strength. They have the property of self-cleaning. They are well applied to the surface in a thin layer, maintain the homogeneity of the mass.

Pros:

• plastic;
• vapor permeability;
• after rain, the surfaces covered with them are covered, cleaned of dust and dirt;
• unlimited variety of colors.

Minuses:

• high price.

The ideal option would be a practical, durable and inexpensive facade putty.

Facade fillers are building mixtures specially designed for creating optimally smooth surfaces and the subsequent application of a finishing decorative finishing layer. The terms putty and putty combine one concept and are of German origin, therefore both designations can be found in different sources. The task of a high-quality putty is not only to level the surface, but also to maximally protect the outer walls from the negative effects of external factors.

Do-it-yourself facade putty

Classification by purpose

Fine-dispersed facade finishing materials, depending on the purpose, can be represented by compositions of various sizes and consistencies:

• starting type of putty, better known as base or leveling mixture;
• finishing version of a fine-grained putty with a relatively liquid consistency;
• decorative version of the putty, which allows you to create textured decorative elements;
• wood putty used to level and protect wood surfaces.

Depending on the intensity of the impact of external factors, not only the compositions, but also the technical characteristics of the facade putty mixtures can vary. A high-quality putty must necessarily be vapor-permeable, moisture-resistant, frost-resistant and sufficiently elastic, which will allow you to complete the work by applying paint, decorative tiles, enamels, mosaics or other finishing materials.

Putties differ in composition and characteristics

The base and finishing mixture can be water-resistant, frost-resistant and heat-resistant:

• mixtures with water-repellent qualities minimize the risk of condensation on the surface, which can occur under the influence of rain and vapors. This putty is distinguished by simple and quick application, uniform distribution, compatibility with other types of finishing materials;
• frost-resistant mixtures are used to seal cracks or chips, and increase the surface resistance to low-temperature conditions;
• heat-resistant compounds combine excellent adhesion properties and have proven themselves in the treatment of surfaces exposed to high temperatures.

Putties not only hide irregularities, but also perform protective functions for the facade

Compositional classification

Each putty mixture is characterized by a strictly established production technology composition, the main component of which allows you to select several varieties that have certain advantages and disadvantages.

Cement	Concrete surfaces with deep cracks. Starter, universal and finishing options are available, differing in additives.	Resistance to temperature extremes, affordable price, ease of work.	Shrinkage occurs, layer cracking may occur.
Acrylic	The liquid version evens out and decorates the surface. It is applied with a thickness of 0.1-0.3 cm on a properly prepared and primed surface in advance.	Good moisture resistant material with a high level of strength and elasticity.	Unsuitable for quick repair of deep cracks; sanding requires a respirator.
Latex	The pasty composition has improved moisture resistance and good frost resistance.	Ease of use, high level of plasticity and good protective qualities, durability.	Not too affordable cost.
Silicate	Mineral version of the facade mixture based on liquid glass, produced in a ready-to-use form. Suitable for working on surfaces represented by shell rock and aerated concrete.	High vapor permeability, protects against moisture and dust, has neutral electrostatic properties.	A minimal violation of the application technology can provoke the appearance of cracks.
Oil and glue	A high level of density of the composition can affect the uniformity of the applied layer, therefore, certain skills are required in finishing work.	A budget option with high protective properties.	Considerable weight and high density, inconvenience of application on vertical surfaces.
Gypsum	The presence of polystyrene in the composition indicates frost resistance, and latex additives improve the water-repellent properties. The mixture can be presented in powder and liquid form.	Durable and plastic material with an affordable price and excellent technical characteristics.	There are practically no disadvantages when using quality material from official manufacturers.
Silicone	Elastic material with high vapor permeability and strength. It is applied in a thin and uniform layer.	Plastic and vapor-permeable composition in a variety of colors.	The cost is too high.

Self-preparation of putty

If there is a need to save money on the purchase of factory mixes, it makes sense to prepare the putty yourself:

• for leveling concrete, relatively flat surfaces, it is recommended to prepare a gypsum-chalk mixture by mixing three parts of chalk and a part of gypsum. With uniform mixing, loose ingredients should be gradually poured into a 5% solution based on wood glue. Homemade solution, mixed until smooth, is fast solidifying and should be used immediately after preparation;

Gypsum-chalk putty, mixing

• to level the wooden facade, it is advisable to use an oil mixture, in the manufacture of which a couple of kilograms of drying oil and four kilograms of chalk are mixed, with the addition of a quarter of a kilogram of a desiccant. The composition brought to a boil must be cooled to room temperature.

What are desiccants

Building chalk, calcium carbonate

It should be remembered that the consumption of self-prepared putty will be higher than when applying ready-made mixtures of factory production.

Working tool preparation

To carry out puttying work, you will need to purchase some tools that make it easier to apply and get the most even, smooth surface:

• a fairly wide brush with a soft bristle or a roller, through which the front surface is primed;

Maklovitsa brush

Rollers for priming walls

• construction mixer or electric drill with a nozzle for high-quality mixing of the putty mixture;

Construction mixer

• several spatulas of different sizes, allowing you to process both large areas of the facade, and corners or hard-to-reach areas.

If paint is supposed to be used as a finishing finish for the facade, then the surface must be absolutely flat and smooth, therefore, a well-dried layer of putty will need to be wiped with a special fine-grained mesh.

Grid for grouting putty

Surface preparation

Regardless of the type, the putty must be applied to an absolutely clean, dry and pre-primed surface. It is best to use primer options for putty, which will allow you not to plaster the surface. Universal primers can be used on any surfaces, but many experts consider such materials ineffective, therefore they prefer to use special formulations:

• antiseptic primers protect the surface from fungus;

  Antiseptic primer for indoor and outdoor use

• anti-corrosion primers prevent rust on metal surfaces;

  Alkyd anticorrosive primer GF-021 GOST 25129-82 for metal

• alkyd primers are good for wood processing;

  Alkyd primer for wood "BASE"

• acrylic primers are best for concrete and brick;

  Acrylic primer

• phenolic primers are optimal for metal surfaces.

Step-by-step instructions for the preliminary preparation of the facade surface for the application of a starting putty layer.

Step 1... We remove all external facade decorative elements and antennas that can interfere with the priming process.

Step 2. We fix all loose elements on the front surface or remove them completely.

Facade surface preparation

Step 3... The outer surface is cleaned from dust accumulations with a wet or dry brush with medium hard bristles.

Facade cleaning

Step 4. We remove heavy dirt and layers of fat deposits on the surface with a damp cloth. Too strong dirt and paint residues can be removed with solvents, after which the surface is washed with clean water.

Step 5. Using a construction roller, carefully apply the prepared primer solution in a thin but even layer.

Spraying primer

Priming with a brush

Roller priming

Depending on the composition and weather conditions, the drying process of the primer can take from four hours to a day or more.

Starting layer technology

The starting mixtures are coarser and coarser. They are used for rough finishing of the facade and have good adhesion to concrete, lime, brick and other substrates. They allow filling seams, deep cracks and other large defects.

Starting putty - what is it for and what is it good for

Depending on the initial state of the facade, the working solution can be applied in a layer of several millimeters or centimeters. It is recommended to apply the starting solution thinly, but in several tiers. In this case, it is possible to obtain a better quality finish.

Step 1. We dilute cement and gypsum putty compounds with clean water in the proportion recommended by the manufacturer. Polymer compounds are ready for use and only need to be mixed before application.

Putty solution

Step 2. We collect a small amount of working solution on a construction trowel, after which we apply it to the surface with a sweeping and fairly wide movement. In the process of application, the spatula must be pressed firmly enough to the surface at a stable angle of inclination.

Step 3. Smear all sagging and irregularities immediately with an empty spatula, and carefully remove excess mixture.

Plastered walls

Step 4. After the solution has solidified, we perform thorough grinding, which allows us to get rid of small defects and makes the surface even and as smooth as possible.

Grinding

Facades with strong irregularities must be leveled in several steps.

Fast-setting self-made compositions or solutions diluted on the basis of dry ready-made mixtures cannot be stored. They are used as soon as possible.

Features of the finishing putty

The main features of applying putty on the wall

The composition of the finishing putty mixtures is represented by fine-grained fractions, due to which the treated structure acquires a smooth and durable structure. Coarse-grained putties based on quartz sand or marble chips can also be used, designed to create a relief and highly decorative texture of the facade.

In recent years, the most popular way to decorate the facade of buildings is the option in which a putty is used, which is subsequently pigmented with high-quality dyes. Quite often, this method is combined with facing work with natural or artificial material.

Leveling the finishing putty

The finishing putty will improve the quality of the subsequent decorative finish

Facade putty can be applied not only manually, but also mechanically, using special equipment. The disadvantage of mechanical application is the lack of the most even application.

Main manufacturers

Putties on the domestic construction market can be presented by both foreign and Russian manufacturers. Of particular interest to the consumer is the products of the middle price category with high product characteristics.

Putty work can be performed independently, even in the absence of building experience, but in this case the following recommendations cannot be neglected:

• the surface of the facade must be prepared in advance, cleaned with a brush with metal bristles and carefully primed;
• moisture-resistant, frost-resistant and embossed putty mixtures can be applied to the facade surface only at positive temperature indicators;
• at subzero temperatures, winter putty such as "Rusean", "Kreps" and "VGT" should be used;

  VGT putty

• the filling technology may vary depending on the type of material, but the simplest and most affordable way is to apply on beacons, which will allow you to get the layer that is optimal in thickness;
• under each putty layer, a deep-acting primer solution must be applied, which contributes to an increase in adhesion between the base and the applied composition;

  Choose primer and filler from the same manufacturer

• The putty mixture for painting the facade should be white, since gray putties can negatively affect the decorative indicators of the finish.

What kind of facade putty for outdoor use is currently on the market? Let's find out together what types of putty exist, what these or those compositions are used for, and what brands make a quality product. And for homemade ones, I will tell you how to putty the facade of a house for painting with your own hands in two ways.

Facade plastering is one of the main stages of home improvement.

What the market offers us

The question of how to putty the facade is far from idle, because the facade putty for outdoor work can have a different composition, be intended for different types of base and even differ in layers, that is, each layer has its own mixture.

Division of mixtures by purpose

Before asking the price of the putty and thinking which one to choose so that the budget does not "crack", decide for what purpose it is needed:

• Starter or base- these compounds are intended for primary leveling of the surface and have good adhesion. But you cannot perfectly align the wall, for example, for painting, the mixture has a too coarse fraction and no matter how much you grind it, you still cannot achieve gloss. The layer thickness here can be up to 20 mm;
• Finishing Lineups- designed for perfect alignment. Such putties are supposed to be applied over the starting ones, but on a flat wall, for example, on plaster, the finish is applied immediately. The thickness of the layer does not exceed 4 mm, therefore, the consumption of putty per 1 m2 for facade plaster is less, but the price for these mixtures is higher;
• Decorative putty- the main purpose of such compositions is the original decor of the facade, but along with this, they do an excellent job of protecting the walls from weather troubles. Fraction and method of application may differ, but the thickness of the decorative layer, as a rule, does not exceed 5–7 mm;
• Compositions for finishing wooden houses now they are singled out in a separate category, although this is a controversial issue. Only vapor-permeable, waterproof facade putty is used here, because there is moisture both in the atmosphere outside and in the wood itself.

Decorative facade putty can be very varied.

There are also so-called universal compounds, they combine the advantages of starting and finishing putties, but such mixtures are not used for facade work, their lot is internal surfaces.

Division of mixtures by composition

The components included in the mixture directly depend on the surfaces for which such a putty is designed.

Illustrations	Recommendations
	Cement putty. Used for concrete and brick surfaces; Withstands any temperature extremes, has an affordable price and is easy to apply; But it is subject to shrinkage and cracks when quickly dried.
	Acrylic putty. It is mainly represented by finishing compounds, can only be applied to a prepared surface and has unique strength. The only negative is expensive.
	Acrylate putty. Pure latex putty is used for interior work; there are acrylate compounds for facades. Acrylate mixtures are immediately ready for use and are considered to be one of the most water resistant.
	Silicate compounds. These compounds are used more in the decorative niche. Focused on aerated concrete and shell rock, although there are models for all types of bases.
	Oil and adhesives. They have increased frost resistance and an affordable price. It is often used to decorate wooden houses.
	Silicone plaster. This is another representative of the polymer line, has good water resistance and can withstand any frost, but the price is high.

How to decorate the facade yourself in two ways

For façade works, façade putty on plaster and reinforced façade putty are mainly used. The fact is that the white finishing putty, which is often used for painting, is expensive and is applied in a thin layer up to 4 mm, so the wall must first be leveled and strengthened, and then putty.

Method number 1. We work on lighthouses

This method is most often used for a facade with really curved walls. In this case, it makes no sense to apply a starting putty on curved walls, because the consumption per 1 m2 will be huge, it is cheaper to plaster the base with a standard cement-sand mortar in a ratio of 1: 4.

Illustrations	Recommendations
	We put up beacons. It is better to buy strips for lighthouses, in this case we took metal profiles, they are cheaper than carbon fiber. We put the planks on gypsum cakes; First, 2 extreme strips are installed; Further, 2-3 threads are pulled between them; Then the rest of the beacons are set along these lines with a step of about 1 m.
	We moisten. We work in the heat in summer, so the wall needs to be moistened with water. In the offseason, you can do without it.
	Priming. No special primer is needed in this case. We just mixed a liquid cement-sand mortar and threw it on the wall.
	Examination. We apply a rule to the lighthouses and check that the soil layer does not "look" beyond the lighthouses.
	Aligning the walls. Now we make a thicker solution and throw it on the wall just above the lighthouses; Further, relying on the lighthouses, as a rule, we remove the excess solution, thereby leveling the wall. You should not pay attention to small shells, we will smear them later.
	We remove the beacons. Since we are going to then putty for painting, we need to pull out the metal beacons: We pry the planks with a pickaxe and pull out; We knock down the remaining plaster; We cover the remaining grooves with a solution and level them with a float or trowel.
	We align. Now we need to align the shallow grooves after the rule: We throw a liquid solution on the wall; We take a wide trowel and rub in the solution. There is no need to take long breaks between stages. The solution should set slightly, but never dry out.
	We overwrite. Now we bring the surface to the ideal: We spray the wall with water; We immediately rub the surface with a float. Grout in a circular motion, slightly pressing down on the grater.
	We apply the primer. The instruction requires to treat the wall with soil before filling, but in such cases I simply moisten the fresh wet plaster with water.
	We knead the putty. First, pour the required amount of water into the container (indicated on the package); Then pour out the dry mixture; Mix everything with a mixer until a pasty state; Let stand for 5-7 minutes and mix again.
	We apply putty. In small portions, with a narrow spatula, apply the composition to a wide spatula or trowel and apply the putty in a circular motion. Since our walls are perfectly flat, you can immediately putty with a finishing compound.
	We grind. You can grind with emery, but the skin clogs up quickly, so I recommend pulling a sanding mesh over the shoe and working. At the end of sanding, all you have to do is dust off the wall, apply a primer for painting and paint the house when it dries. In theory, the wall after sanding can not be primed, but the paint consumption will increase by a third, and it is more expensive than the primer. The video in this article shows the subtleties of the work clearly.

Method number 2. We reinforce the walls

This method is suitable for a facade with smooth walls, as well as for filling insulation boards, for example, extruded polystyrene foam.

Illustrations	Recommendations
	Base mix. As a base mixture, I use a cement-based facade adhesive. This mixture is frost-resistant and "clings" to the wall tightly. For brick or concrete, you can take "Moment", it is cheaper, for expanded polystyrene it is better to buy "Ceresit-CT83". After mixing, the adhesive is applied to the wall with a notched trowel with a tooth of 10–12 mm. We move from bottom to top.
	We put a corner. The first is a plastic corner with a reinforcing mesh. After you slightly submerge the corner in the solution, check it vertically.
	We fasten the mesh. Now we cut off the usual fiberglass mesh to the size of the wall and, with an overlap over the mesh of the corner, we melt it into the solution to keep it.
	Primary alignment. Now we need to immerse our mesh completely in the glue mixture. To do this, take a spatula and press the mesh with sweeping movements.
	Putty. Now, using the above technology, we putty the wall. The only difference is that first we apply and lightly grind the starting coarse-grained composition, and a white finishing putty is already placed on it.

Conclusion

As you can see, the facade putty is applied quite simply, the main thing is to choose the right composition for a specific base. If you have any questions, write in the comments, I will try to help.

"Bark beetle" is one of the most common types of putty.

In order to carry out the restoration of the external walls of the building or finishing work on the new facade, preliminary leveling of the surface is required. Only then can you remove small cracks and defects on the base, make it smooth and even. To carry out such work, you will need a good putty. Facade building mixture is suitable for outdoor work, as it has moisture-resistant and heat-resistant functions, which means that it will not be afraid of temperature changes and external adverse factors, such as direct sunlight, snow, rain.

In the online store "Vira-Stroymaterialy" the best putty for facade works from well-known manufacturers is presented for you. We work directly with factories, so we guarantee you the quality of the material and offer you an attractive price.

What substrates is the facade putty applied to?

After the completion of construction, it will take about a year for shrinkage. This time is necessary so that the surface does not crack in the future after applying putty and other materials. If there are no major defects on the substrate, no preliminary work is required before applying the finishing materials.

Facade putty, as a rule, has a cement base, so it fits perfectly on such bases as:

• plaster;
• drywall and other gypsum bases;
• brick;
• cellular and other types of concrete.

After the outdoor putty has been applied and dried, you can do cladding, fix mosaics or paint.

How to choose the best filler for outdoor use?

The material for outdoor use must have certain qualities in order to maintain its properties for a long time.

Among them:

• weather resistance (the putty must, even without another coating, withstand the influence of temperature, sunlight and weather conditions);
• good strength (the facade finish is exposed to serious mechanical stress, so it should not crumble in case of accidental impacts);
• frost resistance (putty must have good frost resistance characteristics and retain its qualities even with repeated freezing and thawing);
• increased moisture resistance (putty should not absorb excess moisture, deform from collision with water).
