The use of high-quality waterproofing materials selected in accordance with the conditions of operation makes it possible to increase reliability and reduce the cost of maintenance and repair of buildings, roads, engineering infrastructure and communal facilities. Therefore, the polymer waterproofing, the sale of which the company "MPKM" is engaged in demand and is widely used in the construction industry.

Elastic polymer waterproofing Depending on the spectrum of solved tasks, it can be used as an independent waterproofing material or an additional means that improves the reliability of other methods for ensuring the waterproof of concrete. Different brands and compositions on a polyurethane base can protect building structures not only from water, but also from chemically active and aggressive substances, the impact of which causes the destruction of reinforced concrete structures.

Advantages of polymer waterproofing

The effectiveness of waterproofing materials containing epoxy resins and polymeric additives is due to the chemical resistance, durability and elasticity of the film, which is formed when applied protective compositions on the base.

• Elasticity allows partially to compensate for the deformation of the base, so the polymer film of waterproofing always remains holistic and hermetic.
• Materials based on polymers are characterized by good adhesion to concrete, brick, cement plaster, tile, metal and other materials. They can be applied to absorbing and inevitable bases. The waterproofing layer can serve as the basis for spray concrete or finishing materials.
• Polymer waterproofing of concrete allows you to process the surface of a complex shape. Coatings accurately repeat the base outlines and do not have seams that reduce protection efficiency.

Polyurethane based materials are very technological. They are rapidly applied to pre-prepared foundations: liquid polymer waterproofing with pulverizers or special equipment for spraying two-component compositions, and pasty mixtures with conventional brushes, brushes and rollers.

Polymer waterproofing

Polymer waterproofing

Recently, waterproofing materials of different types have recently obtained. Quite common polymer isolationpresented in the market almost the largest number of brands and materials.

The use of polymer is one of the most promising ways to develop construction, since polymeric materials provide increased resistance of structures and buildings to aggressive effects of the environment, as well as restoring the lost structure of the structure.

To date, the most widely used the most widely distribution was the most widespread. The following efficient waterproofing materials were obtained: bitumen-polymeric, acrylic and polyurethane.

Polymer waterproofing Used for all types of structures. Its most effectively use in waterproofing industrial reinforced concrete and sanitary facilities, various treatment plants of household, industrial and sewage drain, as well as containers for storing harmful liquids and full-fledged chemical protection of concrete. In the overwhelming majority of cases, it is used in the form of mastic for the coating of the outer parts of structures and structures.

Polymer compositions are intended mainly for waterproofing various dry surfaces, but there are compounds with special surfactant additives that significantly increase the adhesion of materials to raw base. They are designed for waterproofing wet concrete surfaces. Most often, polymeric formulations are prepared right at the place of work, for which a polymer cocktail is mixed from a resin, plasticizer and hardener. Depending on the composition and purpose of the material, the period of viability of the prepared solution is from a few minutes to several hours.

Bituminous and polymer compositions are good-quality materials based on bitumens diluted with polymers and rubber. These additives have improved waterproofability, durability and deformity of bitumen mastics, and they also regulate the operational and technological properties of bitumen-polymer compositions. Bituminous polymer compositions - the development of waterproofing technology by bitumen, inexpensive, but not too durable. Thanks to the addition of materials of a new type, it was possible to get even relatively inexpensive, but already durable and high-quality waterproofing.

In general, polymer waterproofing is confidently gaining popularity among domestic consumers. The main advantage of materials of this group is a relatively low cost with a rather high quality of the insulating layer.

Cement waterproofing ensures the protection of various structures from moisture exposure. Materials of this group are used often due to a variety of advantages. With proper mixing of the components, high reliability is ensured, the service life of the coating is increased. There are different types of cement-based mixtures. When choosing, they take into account their composition, properties.

Features

Waterproofing mixtures are used to protect different surfaces from water: floor, walls and ceilings, seams and, etc. The distribution was obtained by cement-based materials. This is due to an acceptable price, relatively simple use.

Despite the fact that the cement absorbs a certain amount of moisture, mixtures containing such a component provide high protection against water exposure. At the same time, there are no contradiction properties, since special additives are used in the manufacture of waterproofing on a cement basis, many times improving material characteristics.

For waterproofing surfaces, formulations containing a straining cement are used. It is distinguished by increased strength, resistance to crack formation. Compared to other brands, such cement absorbs moisture minimally. The use of hydrophobic additives, plasticizers contributes to an increase in water resistance, strengthening reliability due to an increase in the plasticity of the mixture.

Waterproofing is applied with a layer of essential thickness, due to which the processed design is better protected. The principle of applying is similar to the use of plaster mixtures. Thanks to the waterproofing layer, condensate is not formed, which gradually destroys the design and cladding. As a result, the attached surfaces remain the attractiveness longer, they also serve for a long time.

Pros and cons

Positive traits:

• wide scope: protection of the foundation, the fencing of single-storey and multi-storey buildings, waterproofing of pools and tanks in contact with water, preparation for lining of bathrooms, balconies, applying on structures that are exposed to a substantial pressure of water under pressure, during room flooding;
• high degree of protection against moisture influence, cement-based waterproofing can be used in any conditions, even in the most complex;
• simple principle of use;
• the possibility of applying to a moistened surface, which is due to the presence in the composition of cement, the adhesion of which is only increasing, if it is pre-increased the moisture content of the protected surface;
• ensuring protection against corrosion;
• lack of a chemical reaction in contact with aggressive media;
• resistance to low temperatures;
• vapor permeability;
• no harmful components.

There are few disadvantages of such mixtures. It is noted that applying only on the designs that have already gained strength. In addition, waterproofing materials based on cement provide a high degree of protection, provided that several layers of material are applied to the fired structural design.

Varieties in composition

When choosing, the type of components, the structure of the mixture takes into account. The material is selected with the purpose of the desired design of the structural design, the operating conditions. Waterproofing should correspond to the temperature regime at which it will be applied and serve in the future. Violation of this condition will lead to gradual destruction of the protective layer.

Cement and sandwaterproofing

The composition is produced in the form of a dry mixture. This is the easiest of the properties of the waterproofing type, which is due to the use of cement as the main component. The mixture is sufficiently rigid, in the drying process, the protective coating should often be moistened - up to 3 times a day for 2 weeks.

For application it is recommended to use the composition of the spraying of the composition by means of special equipment. The main target purpose of the cement-sand mix is \u200b\u200bthe protection of the monolithic base of objects. If it is planned to apply waterproofing with your own hands, to increase the density of the composition you need to introduce special additives. Without them, the life of waterproofing will be reduced, and the coating will not perform its functions.

The mixture is applied sequentially several times. When the works are finished, it is recommended to protect the feen design from possible damage for drying time.

However, the surface of the waterproofing layer can still be deformed. In this case, the moisture evaporates unevenly, which leads to a change in volume with different intensity.

With the addition of latex

Due to this composition, the plasticity of the material is ensured. Latex increases waterproofing resistance to crack formation. The material is much better to carry the effect of temperature differences and low values \u200b\u200bof this parameter. As a result, the cement mixture resembles liquid rubber in appearance and properties. After applying the material, an impenetrable coating is obtained, which reliably protects the feen design from moisture.

Latex can be added to the cement mixture yourself, observing the proportion. However, it is much easier to use the finished mixture.

• the use of the method of torsion or splashing to the surface, which was previously thoroughly prepared;
• the mixture should be hot.

As a result, a seamless coating is obtained, which does not let moisture, does not crack, is distinguished by resistance to mechanical loads and serves a long time, and also withstands the effects of high temperatures.

With liquid glass

This component is added to the cement mixture, which makes it possible to improve the properties of the rigid cement-sandy solution. Most often, the material is used to protect the foundation, ground floors, for the formation of refractory coatings.

• protection against exposure to high temperatures;
• high adhesion;
• manifestation of antiseptic properties;
• the absence of toxic components in the composition.

• the liquid glass is applied to the seams, joints, cracks, this option is used as an auxiliary measure, after applying the waterproofing of this species, the rolled material is used;
• liquid glass is used as the main component of the cement mixture intended for filling the foundation.

Cement-polymer

The composition includes portland cement, sand, plasticizers. Cement-polymer waterproofing is characterized by improved properties. The main advantage of such a material is the high resistance to the exposure to stretching loads and the gap. This is due to the formation of molecular bonds when combining polymer components and cement. As a result, the feen design well tolerates dynamic loads, it is distinguished by resistance to the formation of cracks.

Distinguish different types of polymer cement mixtures:

• waterproofing glue;
• waterproofing.

There are single and two-component compositions. Moreover, the second one of the options is stronger. It includes an acrylic emulsion, microfiber. Such material is used when there is a high risk of exposure to deformation loads (cracks more than 1 mm are formed). In other cases, it is possible to use dry one-component mixtures.

Types of compositions according to the method of application

Materials differ in structure and method of application. The choice is made taking into account the state of the feen design. Penetrating compositions are more preferable for use on surfaces that differ in porosity. Cement waterproofing of coating type, plaster and elastic coating mixture are applied to the surface. Separate types of materials are intended only for repairing objects.

Refractory

This is the most common mixture, it is used to protect different surfaces during construction and at the repair stage: floor, walls, ceilings, balconies, bathrooms, foundations, water tanks. Refractory waterproofing allows you to create an impenetrable layer on a fixed surface, which thoroughly protects from water.

Operated for a long period, fills the smallest cracks. This composition can be applied on the surface from different materials: plasterboard, metal, brick, wood, concrete, etc.

Elastic coating

This group includes materials containing plasticizers. These are auxiliary components that are used to increase the elasticity of cement composition. This type of mixture is recommended to be used to protect the surfaces of a complex configuration, inclined to the formation of small web-shaped cracks up to 0.5 mm wide.

The advantages of elastic waterproofing include increased strength. It is permissible to apply it on the surface: basin, terrace, balcony, water tank. From the classic waterproofing of a coating type is characterized by a high price.

Plaster

This variant of the material is susceptible to cracking, so it is not recommended to use it at elevated dynamic loads. The surface of the feen design should not be deformed, then the essential duration of the waterproofing service is ensured. To improve properties, it is allowed to add auxiliary components, such as liquid glass. This type of material has the advantage - the ability to align curved surfaces and simultaneously provide protection against moisture.

Penetrating

Waterproofing of this species can only be used to protect constructions from concrete and reinforced concrete. This is due to the fact that the composition ensures efficiency, provided that the fenmost surface is porous. Waterproofing penetrates the structure of concrete, when contacting the moisture contained in such material, crystallizes, clogging pores.

This allows you to prevent the risk of moisture penetration. This composition is used when there is no possibility to protect the outer surfaces of the structure using external waterproofing.

Repair compounds

Different dry drying speed. This type of material is recommended to be used to fill the seams, cracks. It is permissible to apply on different surfaces, including when restoring the foundation. The benefits of this mixture include the absence of shrinkage during drying.

Water plug

The material is used when it is necessary to quickly restore the integrity of concrete pressure structures. Used to repair objects from stone, concrete, reinforced concrete. Released in dry form. When in contact with water, when it is a blockage with a mixture of a deformed area in the thickness of the design of concrete or stone, the cement composition instantly hardens, forming an impenetrable water barrier. The advantage of the water plug is high adhesion with a fired surface. It is used even in the presence of leaks.

Application technology

Instruction:

1. If the base is old, it is repaired: remove the top layer, purified, aligned with special mixtures.
2. Before using cement formulations, the surface is moistened.
3. When an excess of moisture evaporates, and the feen design will be weakly moisturized, waterproofing is applied.
4. The paper use a spatula or special equipment for spraying the mixture.
5. The material is applied several times. After the formation of the first layer, we need to wait 2-3 days, during this period the surface is moistened.
6. For 3 days, until the first layer is dry, the following is applied, and then one more. It is impossible to allow waterproofing based on cement coated dry surface.

Manufacturers

To purchase high-quality certified material, we consider the products of common stamps. It should be borne in mind that in Moscow and the regions prices will differ.

Ceresit CR 65.

This is cement rigid waterproofing. Application area:

• internal and external surfaces;
• blowed in the soil structure;
• bathtub bath and other tanks;
• protection of walls, gender and ceiling in rooms with high humidity;
• waterproofing of hydraulic and sewage treatment facilities;
• protection of different objects from the destruction and exposure to low temperatures.

Elasticizer is added to the deformable objects before using the mixture.

Bergauf Hydrostop.

Waterproofing belongs to the group of refractory type materials. This is a single-component mixture, applied with a thickness of 1-5 mm. The strength is gaining in 28 days, it is distinguished by resistant to bending and compression loads. The composition can be used in conditions of high and low temperatures: -50 ... + 70 ° C.

Cement NC.

The strain cement refers to a separate group of materials, since it differs in a high indicator of linear extension, not exposed to a shrinkage, not deformed. This is the most durable substance, and also wins in comparison with the portland cement in moisture resistance. The material almost does not contain pores, so it protects well from moisture.

Waterproofing of wet premises is an important factor in a healthy and comfortable microclimate in all residential space. This is a barrier to penetrate moisture from bathrooms, shower and bathrooms - the most raw rooms in any apartment. Until recently, waterproofing materials based on organic components were most popular and frequently used - bitumen and bitumen-polymer mastic. However, modern polymer waterproofing is much more "advanced" and high-tech material.

What should be high-quality waterproofing, what criteria should be fit? The main task is to prevent the penetration of moisture from one premises to others. Moisture, falling into the thickness of the walls, destroys the brickwork and the plaster layer, forms foci of fungus and mold under wallpaper and putty, spoils the appearance of the repair and mood of the owners. Therefore, it is necessary to fight with it by all available methods, but it is better to use materials specifically for this purpose.

According to the application method, waterproofing materials have always been divided into rolled and coating. The first is more difficult in the installation, and the result was not always reliable - this is already "yesterday". Materials that are applied to the surface with a brush or roller, much more convenient and more reliable. These include polymer cement waterproofing.

This group of materials is based on inorganic substances and has several advantages over traditional bitumen mastic.

Materials are manufactured by many manufacturers who patent their developments and technologies, but in general, the same components include the same components: portland cement, sand of fine grinding, elastic polymeric substances. Single-component and two-component mixtures are available. The first in their composition dispersion polymers in the form of powders (DPP), the second contain aqueous polyacryl dispersions as an elasticizer.

Simplicity of application - one of the advantages of polymer cement waterproofing

Advantages of polymer-cement waterproofing materials

• The waterproofing compositions are completely consisting of substances safe for health, so they can be used indoors intended for people living.
• Waterproofing based on inorganic materials has a significantly longer service life compared to bitumen. These materials have excellent adhesion to all materials used in construction - concrete, brick, wood, metal.
• Easy application - cement-polymer waterproofing is applied on the surface using a conventional painting brush. This allows you to qualitatively to miss the slightest irregularities, because it is clearly visible, where the composition was applied unevenly and in the layer of material there are "propellas". Coating repair is also very simple.
• The waterproofing layer is completely blocking the path of water, while it passes the water pairs - the wall "breathes". This property eliminates the formation of air bubbles under the membrane. The main feature of this material is the possibility of applying it even on a wet wall, moreover, it is recommended to moisturize the surface before starting work.
• The resulting layer has high plasticity and stability to deformities, which eliminates its damage in the event of small cracks on the basis.

The advantage of polymer cement compositions is the possibility of applying to wet surfaces.

Step-by-Step Guide to Waterproof Bathroom Polymer Composites

Using this type of materials, you can get a great result. To do this, it is necessary to carefully follow the recommendations of the manufacturer to apply cement-polymer waterproofing. In general, they are about the same, differences can only be in numbers - the time of drying the layer, the thickness, and in the method of preparing the material to work. Before starting work, it is necessary to note those "wet" zones that will be susceptible to the enhanced moisture - walls around the bath, washbasin, etc. Mandatory coating is applied to the lower part of all walls (25-30 cm) and the entire area of \u200b\u200bthe floor.

In particularly careful processing need "wet" bathroom areas

1. Preparation of the base (walls, gender) must be carried out with all thoroughness. It is necessary to remove all the garbage and dirt, dried splashes of mortars. Rights are filled with plaster.
2. Typically, the manufacturer indicates the need for wetting surfaces before applying the composition. If this remark is, it is necessary to moisten the base using an ordinary spacing.
3. Preparation of material: mixing of all components of the polymer-cement composition in the sequence specified by the manufacturer. The mixture must acquire homogeneity.
4. The composition is applied to all marked surfaces with a rigid brush with a uniform layer. Carefully make sure that there were no "non-projects". In places of the adjoining of walls and gender, as well as pipeline pipes, sewage or risers, it is necessary to lay a layer of construction grid from polypropylene, geotextile, etc. material. It is interpreted into the layer of waterproofing material and is well urged.
5. The first layer is dried over the time specified in the manufacturer's instructions. It is better not to reduce artificially this period by drying with thermal guns or construction facilities.
6. Before applying the second layer of material, the surface is slightly wetted again (if recommended by the manufacturer). The second waterproofing layer is applied.
7. The surface is dried according to the recommendations of the material supplier, after which it is ready to apply decorative trim.

The joints of the walls and the floor of the bathroom must be punctured by waterproofing ribbon

Features of polymer coating waterproofing

This group of materials also relates to modern one-component coating compositions for the "cut-off" of moisture. They contain acrylic, epoxy or polyurethane resins that report to them very high plasticity. Surface active substances increase the adhesive properties of polymer compositions for waterproofing work. The resulting layer has high vapor permeability, it is very elastic, but durable, similar to rubber. Application of this material is made with a brush or roller, and the surface is pre-moistened.

Let the polymer waterproofing for the bathroom are not subject to the aggressive influence of chemicals, but, nevertheless, it is very resistant to this kind of impacts, therefore it is most often used for work in the open air - with waterproofing of pools, sewer and wastewater treatment facilities, etc. Materials intended for use indoors can be performed in a wide range of colors, under the action of ultraviolet on the street they fade very quickly.

Indoors can be used polymer waterproofing of any color

General recommendations for the use of polymer waterproofing compositions

1. When applying any materials, be it wallpaper, paint or waterproofing formulations, the preparation of the base is very important. Mark the zones on the walls that will be exposed to increased moisture. Be sure to waterproofing are also subjected to the lower part of the walls and the entire floor.
2. The walls and the floor should be well dusty, cleaned from the influx of the solution or plaster, the large potholes need to be aligned. Carefully removes all the garbage. The surface should be dry.
3. Concrete, metal surfaces are grounded by special primers recommended by the manufacturer.
4. The composition of the first layer is applied at temperatures above 0 ° C, the exact time of hardening is indicated on the packaging by the manufacturer; This is necessary for the polymerization of the applied composition. In places of flooring and walls, as well as outlets of risers and pipes, it is desirable to lay a layer of geotextile or polypropylene construction grid. The material is well absorbing and interpreted into the waterproofing layer.
5. After hardening the first layer, the second is applied. In order to be more convenient to monitor the uniform of the application of the second layer, it is better to make a contrast color. In places where the bottom layer shines, after the second layer, the second layer must be applied to the mastic again.
6. After rejection of the second layer of the surface, ready for decorative finish.

Polymer waterproofing in the bathroom

In general, the process of applying modern waterproofing compositions is quite simple. However, as in every work, it has a number of subtleties familiar to those skilled in the art. So that your bathroom shone purity, and the walls of the neighboring premises were dry, invite professionals, and let everyone do their own business!
