How to prepare a solution for plastering walls: proportions, purpose and consumption of material. How to prepare a cement solution for wall plaster: composition and proportion of the proportion of plaster mortar for external

The composition of the plaster is known if not everyone, it is very many. It would seem, there is nothing unusual in it, and its components are not a deficit. However, cooking plastering Requires attentiveness I. strict adherence proportions, otherwise the solution simply does not fall on the wall or later a short time Start crack and flaw from the surface. There are several types of plaster mixtures, each of which is used when performing certain works. The composition of the solution for plastering walls indoors is different from the one that is necessary to create a protective layer on the outer walls.

What is plaster

Plaster - facing material, rather rough, performing protective functions in relation to the surfaces of the facade and inland walls. For the preparation of the plastering, various components and components, tools and technologies are used, but they seek to achieve one goal. This goal is to create high quality, durable, reliable coverage on the walls of the building.

Before preparing a solution for plastering walls, you will need to stock yourself:

1. The basis, which is most often used cement. It is also called a binder that ensures the strength of the finished mixture.
2. The filler by which the volume of the solution is significantly increasing, there is a solid connection between the particles of the mixture.
3. The liquid (of course water), which, by preparing the solution for plaster, is added to a strictly defined volume. Surplus, as well as the lack of moisture in the solution, will lead to its cracking and rapid destruction.

There are several types of compositions designed to shock the walls. Their main difference is the material used as a basis, but, in addition, each of these compositions is created to create a coating on certain surfaces.

Beginning builders often think that the preparation of a solution for plaster is the usual mixing of the cement of sand and water, but to create a high-quality mixture and indeed durable coating On the walls, it is necessary to strictly observe the proportion and take into account the possibility of introducing some additional components into the solution.

For example, in some cases, it is added to lime, despite the fact that the substance does not differ in durability and when drying it quickly crumbs and crumbles. As a component for plastering walls, the proportions of which indicate the need to add a certain amount of this white powder, the lime is used as a means for increasing the plasticity of the solution. Gypsum quickly freezes and contributes to the quick solidification of plastering mixtures.

Clay is a component without which it is impossible to imagine the process of plastering the furnaces. Its main distinctive feature is a set of strength after firing.

The main condition is exactly observed proportions for plaster. But no less important right choice Basics of mixture I. different components Depending on the operating conditions of the created coating.

Cement mortar

Cement mortar For plaster is the most popular and popular when performing different workrelated to the draft wall walls of the building. Its main advantage is a high level of strength. To obtain a high-quality mixture, it is important to know not only how to distribute cement for plaster, but also which components and in what quantities should be present in the solution.

How to make a mortar for plastering from cement? You will need to prepare the exact amount of each of the required components. First of all, we are talking directly about cement. Depending on how the qualities should have a cooked solution, the cement brand is chosen. To plastering the outer walls of the building, the cement brand M 200 - M 300 is most often used. The mixture prepared on the basis of such a binder will be different high levels strength and suitable for creating draft finishing coat On the facade of the building.

The proportions of the cement mortar for plaster are greatly important:

• cement brand M 300 - 1 part;
• sand small seeded - 3 parts;
• water is added in such a volume so that the mixture obtained reminds thick sour cream.

The amount of water depends on the humidity of the sand, therefore the exact number of buckets used in the preparation of cement-sand mixture cannot be specified.

The solution for plastering walls, consisting of cement of sand and water, has only one astringent (cement) in its composition, and therefore belongs to the number of simple. Complex or multicomponent is called mixtures that include two or more binding components. Important condition Preparation of a high-quality solution for plastering is the refusal to add any components during the mixing process.

Before making a solution for plastering from cement, you will need to prepare a container in which all components could be freely mixed. First, cement and sand are poured there, mix both components and poured with water, introducing it into the solution gradually and achieving the desired consistency of the mixture.

An important characteristic is the fat content of the solution, which can be determined by how the composition behaves on the chapter:

• Pins to the instrument - high fatty and to create a high-quality coating requires a small amount of filler to solution.
• It is not delayed on the workshop - the solution is skinny, it is possible to correct the position by adding a binder.

The ratio of the filler and the binder is correct if, after manual mixing, a thin layer of solution remains on the trinket.

Lime

Composition lime solutions For plaster, it is similar to proportions with a mortar based on cement. To prepare the mixture, it will be necessary to directly lime and sand in the ratio of 1: 3.

Before making a lime solution for plaster, you need to prepare a limestone dough separately. Lime in pure form in the solution is not added.

The cement-limestrine for plastering on 10 parts of the cement is added 4 parts of the lime and 30 (50) parts of the sand. This is the most qualitative composition To apply the first layer of plaster (spray). For the second layer, cement and limestone dough are taken in equal parts, and for the third - lime 1.5 times more than cement.

The time of complete frosting of such a mixture due to the addition of a limestone test increases for two days, but at the same time increases the level of strength of the finished coating. Before making a solution for plastering walls with adding to its composition of negated lime, the powder must be pouring to water and leave no less than 14 days. The process of quenching is quite long, and non-compliance with technology leads to the creation of a poor-quality mixture, which, after complete drying, begins cracking and disappear from the surface.

The process of preparing the solution requires primarily mixing dry components, then add a limestone dough and only after that enter water, constantly stirring all the components of the solution until a homogeneous mixture is obtained. The resulting solution should not be lumps.

Preparation of a lime solution for plaster begins with the addition of a small amount of sand into the finished limestone dough. The amount of pure sainted sand should be at least 3 parts per 1 part of the hazed lime. Thoroughly mixing the components, proceed to the gradual addition of water.

Gypsum and clay plaster

A gypsum solution for plaster is not particularly durable, it does not tolerate the destructive action of moisture and therefore is usually used when performing work indoors. You can increase the level of strength by adding a little cement to the solution. Before they prepare plaster based on plaster, the content in the solution of sand and cement is calculated.

Gypsum plaster quickly frozen on the treated surface, so professionals or people who have certain experience and skills of working with similar compositions work in such a solution.

Before starting work, the entire surface of the wall is divided into sections, the area of \u200b\u200beach of which does not exceed 1 m 2.

This action is necessary because this mixture for plastering is characterized by minimal drying time. Getting Started to prepare a solution, first mix the sand and lime or cement, and then in a separate container, the construction gypsum (alabaster) is mixed with big amount water. Now gradually add gypsum mixture To cement with sand or limestone, mixed with sand.

Clay stucco Prepared on the basis of alumina, which is pre-soaked in water. The right amount The material is poured with water so that it completely covers alumina and leave no less than 5-6 hours for swelling. The softened clay is thoroughly mixed and added to it three times more sand. The main condition is a gradual addition of all components of the mixture and a constant thorough mixing of the composition. If a clean clay solution is used for plastering furnaces, then after the final mixing it can be immediately applied to the surface.

To work on the walls of samanny houses, use clay plaster with the addition of lime, building gypsum Or cement:

• lime dough - 1 part;
• soft clay - 2 parts;
• sandy sand - 6 pieces.

Such a solution can be placed in the inner surface of the walls. In the case when plastering will be carried out outside the building, mix:

• 10 kg of cement;
• 2 kg clay;
• 30 kg of pure sand.

Water is added gradually, following the consistency of the mixture. When using building gypsum you need to be very careful. The clay plaster with the addition of alabaster freezes after 5 minutes, and completely dries after half an hour. That is why they prepare a solution with small portions, apply to small sites Surfaces add alabaster no more than ¼ on the amount of clay. You can familiarize yourself with the subtleties of the process of cooking for plaster with your own hands, looking at the video.

Prepare a solution for plaster with your own hands is not so difficult, but you can not forget about the need to comply with all the rules of existing norms regarding the materials used. It is impossible to disrupt the sequence of work and the established proportions. Only in this case, all performed manipulations will allow to achieve a positive result.

Today we will detail in detail how to make a solution for plastering walls. Also definable where and which composition is better to apply. How to cook a plaster mortar is one question, but there is also different surfaces and weather, so you need to know the conditions for the use of different compositions and then make the purchase of components. Also on the video in this article you can see options, how to make plaster.

How to make a plaster solution, we will look at a little lower, you must first understand which composition will suit in your case. After all, you can do everything with your own hands, then the price of the material will be much cheaper.

You also need to properly prepare the surface. Before the start of the knead, you should make sure that the surface you will end up plastering completely corresponds to the prepared formulation.

• If you are going to conduct outdoor front work Or you need to carry out work in the room with a very high humidity, then for surface treatment, it is better to use solutions with cement content, simply cement or cement with an admixture of lime.
• If the moisture in the building is at the level of the norm, then a solution based on lime or mixture of plaster and lime can be used for finishing.
• If the level of humidity is minimal, and the surfaces processed are also made of stone or wood (see how to plastered the wooden wall), then the most acceptable choice will be solutions based on clays.

Before cooking, pride some nuances:

• It is necessary to sift all the initial reagents. For this, sieves are used, mainly with square cells (sizes of cells or 3x3, or 5x5 mm).
• For the preparation of solutions the container should have a depth of at least one or two centimeters.
• When stirring the solution should be achieved complete homogeneity, without large lumps, otherwise the solution will not be built with the surface of the surface. Use a shovel for mixing, preferably from wood, total length within a meter.
• After the knead, it is required to check the solid: Mind a little wide shovel and give it a drain. If visually the solution is only a bit of a tree adherent, it can be used in operation. If the solution flows slowly, or firmly tightened enough to the blade, then you need to add a dilute, and if it is so liquid, which is not attached at all to the surface, then you need to add source ingredients to increase the viscosity.

Cement mortar

Reception: Standard 2 or 3 Sand parts per part of cement (see Cement-sand plaster: Material features). Sand proportions can be more (up to six parts per part of cement), but then weak bonds will be formed between the components of the solution - it will make difficult all subsequent work.

How to prepare a cement mortar for plaster walls:

• sand pour on the bottom of the tank;
• on top Pop multiple cement layers;
• mix them until the formation of a homogeneous dry mixture;
• gradually add water, stirring the mixture all the time;
• when the solution comes to the consistency of thick sour cream - stop the water supply;
• to improve the taking formation of plaster, you can add a gypsum solution or PVA glue - everything in small quantities. If you need to reduce the grab - you need to add a small amount detergentwhich will create a film on the surface of the solution particles.

Attention: with the addition of PWA, the solution is suitable for operation only for one hour after kneading, then its working properties will begin to deteriorate. It is better to knead a solution with small portions that can be quickly worked out.

To obtain an affordable solution, it is necessary to dissolve a mixture of dry ingredients with water in the right ratio. For this, water should be supplied to a solution with small portions, every time thoroughly mixing the mixture.

Determine the improper ratio of fluid to the mixture in the following indicators:

• Viscous solution - The mixture is saturated with moisture, but not enough diluted, so the solution has a thick state, or a lot of cement is initially laid. After drying the layer of such a solution applied to the surface, it will give a lot of cracks and quickly turns.
• Liquid solution - Excess water that led to a lack of components that give the desired viscosity. Or in the mixture initially laid more than sand. Such a mixture during drying is not a rack and is strongly susceptible to destruction.

So, the correct viscosity is determined - it should be like a thick sour cream. But the rules that should go to surface processing, as such does not exist. The only thing that should be taken into account is the surface area and thickness of the required coating layer.

Cement + lime

Reception: From three to five parts of the sand mixed with one part of the cement, plus 0.7-1 part of the lime solution:

• For the preparation of the solution you use the lime of the left. Bookmark Limits produce in a metal container. Take care of the hands, mucous and eyes - the substance can apply chemical burns.
• Pour warm water from above so that the layer of lime is completely filled. And immediately close the bucket with a lid, putting something heavy on top - quicklime It comes with water into a rapid reaction, and it threatens with a splash of hot liquid.
• After the end of the reaction, it is necessary to strain the solution. Marley will come for this purpose. Let him stand out the day and he is ready to use.
• Prepare a dry mixture: cement mix with sand in proportion 1 to 3rd in mixing containers.
• Then stick there with a standing lime solution and mix thoroughly.

Lime-based solution

Reception, how to make a limestone for plaster: Three parts of the sand are kneaded in one part of the lime solution.

• It is necessary to repay the lime and prepare a lime solution according to the above method.
• 1/3 of sand and a small fraction of water are added to the prepared solution. This is done for better mixing of the mixture. It is necessary to rub the resulting mixture thoroughly, to the complete disappearance of lumps.
• The rest of the sand should be added with small portions, while sticking water into the container.
• The solution will be ready when the consistency becomes an average viscosity and will only slightly adhere to the shovel.

It is impossible to leave the solution for several days, it must be developed completely on the day of preparation.

Lime + Gypsum

Gypsum is mixed with a lime solution one to three:

• gypsum is diluted with water until it acquires the density of the dough;
• to the resulting mass adhere to the solution and mix thoroughly.

Attention: It is necessary to take into account the fact that this solution is fastened in the first minutes after cooking, for no more than 5 minutes, and after 30 minutes it fully solidifies. Therefore, this mass must be applied to the surface instantly quickly.

Solutions with clay

Preparation of a solution with clay looks like a method of kneading a lime solution. But one clay is extremely rarely used in preparation, because it does not have due specifications. In clay suspensions, it is customized to mix cement, gypsum or lime additives.

• in all solutions, the components that give viscosity are mixed with the clay, then the sand is added in parts and everything is carefully laid until a homogeneous mass;
• if you do not have the necessary professional skills, it is necessary to limit the above recipes. And solutions with a variety chemical components Only specialists should prepare.

Attention: the clay composition will be the best for finishing wooden surfaces. It does not harm wood and perfectly protects it.

What mortar plastering - now you need to choose. The instruction is, only the most important thing, always qualitatively prepare the components. After all, when stucco, everything will be reflected on the plane. Never hurry, look at the photo and make it right.

Shuttering - traditional way Alignment of the walls of the buildings and their preparation for the finishing finish, which is mandatory in the construction of any premises during both internal and external work. In the recent past, such works were carried out in the same way using some materials. Today we have a wide range of materials for performing plastering, yes I. finishing technologies Do not stand still. In order to avoid errors, it is necessary to prepare a high-quality solution for these purposes.

Types and characteristics of plaster solutions

For plastering make a solution consisting of a binding component and aggregate. In the role of the binder component, clay, lime or cement can act, the choice of one of them depends on the nature of the upcoming works and the place of their holding (within the task or outside). The sand is traditionally added as a placeholder. If you do not add the aggregate to the binder elements, the plaster will be fragile, and the surface treated in this way will cover cracks. So, the following plaster solutions distinguish:

• cement and cement-lime - used for the outer facade plaster surface of the walls and base, exposed to constant moisturizing; for internal work - when working in rooms with high humidity - bathrooms, kitchen facilities, toilets;
• lime, lime-gypsum and lime-clay - use when outdoor finish walls that are not subjected to systemic moisturization, as well as for internal plastering of rooms in dry rooms;
• clay, cleanium with cement and clay with plaster - are considered quite suitable for internal work on plastering premises with air humidity level, not exceeding the norm, and for outdoor plaster Surfaces of walls in areas with dry climate.

How to determine the quality

When preparing a plaster mortar good quality Pre-starting materials should be sifted through a construction sieve so that the finished solution does not have to be filtered, which in itself is more laborious. The high-quality mixture, ready to work, should have a homogeneous consistency, the necessary fat content, is well fixed on the shuffled surface, not crack when it is drying.

There are plaster solutions of increased fatty, normal fat and skinny.

It should be known that fat solutions have an increased content of the binder component, it leads to a high degree of cracking and shrinkage of the plastered surface. Normal solutions are characterized by a balanced content of all components. And for skinny plaster mixtures, the excessive aggregate content is characterized, leading to the lack of strength of the plaster layer, although the surface is not cracking and not exposed to the shrinkage.

Determine the fat content of the working solution for plastering can be cheered for mixing its components. For this, stirring the components, determine how the plaster mix is \u200b\u200bbehaving:

• needlessly lipnet to the mixer - we got a fatty solution, you should add a placeholder;
• the degree of adhesion is average - we have the composition with normal fatty;
• it does not stick at all - before us is a skinny solution that requires additional introduction of the binder component.

Lime-based solution

1. A lime solution, which includes lime dough and sand in a 1: 3 ratio, is adjusted to the necessary water by adding water with a thorough mixing of the entire composition. When readiness, it should remind of consistency thick, viscous dough.
2. In order to give a plastering solution of strength on a decider volume of limestone plaster mix Add 1/10 part of this cement volume. Thus, a cement-lime solution is obtained. The above-mentioned lime-based compositions are frozen slowly, which allows you to work with them for 2-2.5 days.
3. A lime solution with the addition of gypsum (mixed, respectively, 5 parts to 1 part) is more durable, and it throws up after 6 minutes, the complete rejection occurs after half an hour. This creates certain difficulties and requires special skills, but the plaster will be durable.
4. The lime-clay mixture for plaster is prepared from a 1: 1 clay and lime test taken in the ratio with the addition of five sand parts. This plaster is an order of magnitude stronger than lime and clay.

Based on clay

1. The clay solution for plaster is prepared by a special way, pre-watered the binding component and cover it with a dense cloth. Wake-up clay (1 part) mixed with sawdust (3 parts) and, adding water, brought by stirring to the required consistency. The disadvantages of the clay solution are its fragility and instability to high humidity.
2. In order to make the clay solution, it is stronger, cement is added to it (1/10 of this volume of cement is introduced into the declitron volume of the clay plastering solution). In this way, a solution is obtained with the addition of cement.
3. The clay solution with plaster is obtained similar to lime-gypsum, only the cylinder dough is taken as the main binder component.

Based on cement

Solutions for cement-based plaster applicable mainly for the processing of walls, often exposed to moisture, both indoors and outside.

1. Cement mortar is prepared by mixing cement with sand in a ratio of 1: 3, 1: 4 (depending on the purpose of use), which are diluted with water and, actively stirring, adjust to the desired condition. Use the cooked mixture no longer than one hour. Excess this time of operation with cement mortar leads to a decrease in its quality.
2. The cement-limestone is prepared by mixing one part of the portland cement with the M400 marking or M500, ½ of the limescale and two parts of the washed sand.

This type of solution is prepared in two ways:

• pre-mixing the lime dough with sand, they are reported to the resulting mixture of cement, after that, intensively stirring the composition, pouring water until the required consistency is obtained;
• having made a mixture of sand and cement, thoroughly stirred the solution, fill the lime milk (having received it by connecting 1 part of the water and 1 part of the limestone test).

Use of modern materials

Today increasingly when construction or during repair work Using high-quality dry mixes for plaster, the basis for which is portland cement. These mixtures are usually enriched with various polymeric additives that enhance the plasticity of the solution, its adhesion to the working surface and the strength of the plaster. Such characteristics of the dry mixture provide it with a number of advantages:

• allow you to do without reinforcing mesh and significantly reduce the consumption of plastering solution;
• make the stucco with the elastic, which ensures its soft response to weather changes - the temperature differences or humidity lead to the change of its shape, and not to the deformation;
• allow the plastered surfaces to pass the air and not collapse from the penetration of moisture.

Construction dry mixtures intended for the preparation of plaster solutions were developed by technologists in laboratory conditions, which ensured the accuracy of the proportions of incoming components, the uniformity of the mixture and absolute readiness to use. For an ordinary consumer, it is worth the possibility to prepare a solution, guided by a clear indication: "Add water and work."

Modified Dry Mixes - Achievement innovative technologies - It allows you to apply new thin layer technologies, prepare a solution for plastering in the desired volume as needed that, in turn, makes it convenient to use and significantly reduces costs.

In each case, each surface requires its own kind of solution for plaster. Making it, it is necessary to use high-quality components, for the quality of the solution depends on this, and ultimately, both the quality and durability of the processed surfaces.

Video: Preparations of a plaster solution

It is difficult to imagine a more popular material for finishing ceilings and walls than plaster. It serves for decorative purposes, and maybe intermediate protective coating. Durability and strength of plaster - for it corresponds to its composition.

First of all, it will correctly evaluate the microclimate of the room. For example, a dry climate - it means it is wiser to use a limestone plaster, in normal conditions A cement or cement-limeseer is used.

Types of plastecrops for internal works:

• Cement. It is distinguished by a slow set of strength, the mixture is seized 12 hours after water is introduced into the mixture. At the same time, the remaining compositions are superior to strength.
• Glinian. This solution for plaster is suitable only for processing wooden surfaces.
• Lime. To accelerate the setting and give a solution of high strength, there is sometimes a construction gypsum sometimes.
• Gypsum. There is such a composition. After half an hour, this solution is completely frozen, and after 4 minutes it will grab.
• Combined composition. Several binders are applied at once (for example, lime and cement, or lime and gypsum).
• Special plaster. Due to what the mixture is intended, certain additives are introduced into it.

As for the filler, in most cases the sand is used. You can take river sand. The sea has an excess salt, and this affects the strength of the mixture. Repair sand for the preparation of the mix is \u200b\u200bunsuitable - it is very dirty.

Proportions of solution

To prepare the mixture, we need aggregate, binder and water. In special cases, you can use some additives that give mixtures right qualities. For example, to obtain a waterproof mixture follows to the standard component of the same cement mix Add a nitric acid calcium.

The proportions of binder and aggregate are important:

• Cement plaster. The proportions for the primer layer - 1 part of the volume of binder / 2-3 parts of the aggregate. Layer for finishing - 1 part of the volume of binder / 1.5-2 h. Aggregate.
• Limestone. The proportions for the soil are 1 h binding / 2-3 aggregate. For decoration - 1 hour. Binding / 1-2 h.pillizer.
• Clay composition. The proportions for this mixture - aggregate should be 4-5 times more than the clay itself.
• Limestone mix. Proportions for lime, primer layer - 1 h binding to 2-3 parts of the aggregate, department. The layer is 1 hour. of the binder to 1-2 parts of the aggregate.
• Lime-clay mixture. Proportions: 0, 2 hours. Lime, 1 h. Clay to 3-5 h.
• Cement-clay mixture. Proportions: 1 hour cement - 4 h. Clays - 6-12 h. Sand.

The proportions for the lime-gypsum solution will be such - for one part of the lime on the primer layer, 0.5 or one and a half of the gypsum and 2 hours of sand, for the finishing layer - 1-1.5 hours of plaster (sand for finishing is not added).

How to make a solution with your own hands

If you decide to prepare a lime solution, you need not very much in the dough quartz sand And water, after which it all mix it. Then you gradually add sand until it turns out the desired fatty solution.

Lime in its properties is considered to be a binder, and a plasticizer, because it is well seized with wooden surfaces, and with concrete and brick. Holds such a mixture very slowly.

If you want to speed up the crook of lime, it is necessary to add gypsum into it. Pour water into the container, a thin flowing riveting there plaster, mix well until the liquid solution is obtained. Add a limestone dough to this mixture, mix it all up to homogeneity.

How to make a solution for stove stucco

For these purposes, it is possible to make a simple solution of clay, or to make a more complex, for example, lime-grinding. there is universal recipeswhich are used more often than others.

Types of stucco stoves in proportions:

• 1 unit. clay to 2 units. Sand to 0.1 units. asbestos;
• 1 unit. clay to 2 units. Sand to 1 unit. Lime to 0.1 units. asbestos;
• 1 unit. clay to 2 units. Sand to 1 unit. Cement to 0.1 units. asbestos;
• 1 unit. Gypsum to 2 units. Lime to 1 unit. Sand to 0.2 units. fiberglass;
• 1 unit. Gypsum to 2 units. Lime to 1 unit. Sand to 0.2 units. Asbestos.

If you made a high-quality solution, it will be easily applied to the oven, smoothed well.

How to breed plaster

To get a composition of good quality, the mortar for plastering should be done in all the rules. And they are not so much.

Rules for breeding plaster:

• The selection of the optimal combination of all components of the solution is important;
• Follow the recommendations for proportions;
• The solution must be stuck a few minutes, and then it is mixed again;
• After cooking, you do not need to store the solution, use it immediately, because the mixture is not prepared in advance.

Perhaps you liked some kind of defined construction stamp, and you decided to purchase a ready-made mixture. This is, of course, more convenient, but prepare, mix the solution itself will be significantly cheaper.

1 m² solution consumption

To correctly calculate the flow, you need to determine how the average coating layer will be, the total area of \u200b\u200bthe room, and, of course, the type of mixture. It is also important that the coating value depends on the curvature of the walls. For example, the irregularities of new walls - 25 mm, older houses have big irregularities.

Since curvature needs to be aligned, more layers will be used. Calculate the layer thickness, well, if you use laser level. Determine the control places where deviations from the plane are measured.

Data examples:

• The thickness of the plaster is one and a half cm, limescale in M3 needed - 0.012, gypsum - 6.4 kg, water - 7 l;
• The thickness of the plaster 3 cm, limescale in m3 - 0.024, gypsum - 12.1 kg, water - 13 liters.

If you are plastering the ceilings, the composition will increase the flow rate by 1%. And thicker layer of plaster needs to be applied only in places of irregularities.

And one more point - often the plaster rinsing the neutralizing solution. It helps renew the plaster life and protect from mold and fungus

Sitting for plastering walls (video)

If you feel that the mixture is easily applied, it means that it is made correctly.

Alignment of walls by plaster - one of the main stages of pre-state work, which affects the quality of repair, durability and aesthetics finish finish. Here, more often than others, a limestone solution for plaster is used - durable, easy to work, relatively inexpensive, proven time.

In the article, we will tell you how to make a lime solution for plaster, we will examine several recipes for the preparation of the mixture, how much to write lime into a solution for plaster, we will tell about the advantages and disadvantages, make comparative characteristic relative to the finished materials.

Where applies a plaster solution based on lime

Lime mortar for plaster can be called almost versatile for outdoor and internal works. Depending on the composition, the mixture is used to finish residential and production premises, facades, open balconies and loggias, household buildings.

Lime plaster is afraid of a wet environment, so there are restrictions on construction standards:

• it is not recommended to use the composition for finishing raw premises: basements, bathrooms, on facades of buildings in wet climatic belts;
• snip is prohibited to use a limestone solution for internal and external work, where the air humidity exceeds 65%.

The mixture should be thick and homogeneous

Composition of lime mortar for plaster - components, scope, recipes

The plaster mixture consists of a binder and fillers, on lime-based basis Simple solutions are created under painting or pasting wallpaper, compositions for decorative plaster walls and facades. The main difference consists in the components with which the limestone dough will be mixed.

Preparation of lime mortar for plaster

For plaster, exclusively hydrate lime is applied, so it is necessary to rejuven on the work of the coming lime, to the process, until the reaction is complete, it takes 36 hours, but it is recommended to survive a solution of 2 weeks.

Tara for quenching: metal, without signs of corrosion, wooden, plastic. The hydrate lime increases in the amount of up to 3 times, which should be considered when choosing a volume of containers. In the process used only cold water. Lime / water ratio:

• pushons (lime milk) in 1 l ratio of 1 l;
• the dough is 1 kg of lime 0.5 liters of water.

The lime lime is stacked in the container, poured with water, the boiling process begins, by its expiration, the mass is well mixed several times and stands. Before use, hydrate lime is passed through a construction sieve.

Gypsum

The lime composition with plaster is applicable to the finishing of eaves, stone, wooden surfaces, for concrete surfaces is not used. Application area - interior decoration walls and ceilings, outside applied in exceptional cases. Grasps quickly, until it is enough to get half an hour, prepares with small portions, in finished video Not stored.

How to prepare gypsum-limestone plaster for internal works: 1 hour. Gypsum for 4 hours. Limestone test. Gypsum is mixed to the state of sour cream in the resulting mixture, lime is added, the solution should be thick, do not flip from the spatula.

The lime-gypsum mixture is distinguished by small graininess, go smoothly

On cement basis

Cement-limestone plaster is a complex, universal, durable solution, suitable for all types of plastering, including facades, bathroom finishes, basements.

The composition of the cement-lime mortar for plaster depends on the scope of application. The mixture usually uses the M400-500 brand cement and the sandstone of the middle fraction, sinking and washed. The more sand, the solution is weaker.

The table of the proportions of the lime-cement mortar for plaster, solutions of different density, calculation of 1 cement bag (25 kg):

Most often, the repair is used precisely the plaster cement-known. Specifications Composition can be improved by additives: for plasticity, the largest clutch and increase moisture resistance add liquid soap: 0.2 l / 20 l Mixtures or PVA glue: 0.5 l / 20 liters of solution.

How to prepare a lime solution for plaster with the addition of cement: Cement and lime are added from the total water volume, the cement is added, all sand is added, when the components are connected to a homogeneous mass poured the water residue and mix well again.
