Putty for the bathroom: features of surface treatment in wet rooms. Finishing waterproof putty Finishing putty for wet rooms

Not only the facade is exposed to water. Moisture-resistant putty should also be for bathrooms, pools and even kitchens. It acquires its qualities thanks to the main component or additives. Often, Portland cement-based materials for outdoor use are used to finish interior walls. Latex putty is used only inside.

Moisture-resistant facade compositions and for damp rooms in the house

Another hail of questions rained down on me when Vadik and I were preparing to finish the walls and ceiling in the pool and bathroom. He was interested in waterproof facade putty, and what materials have such qualities. How gypsum ceases to be hygroscopic. Why latex putty is not popular as an outdoor putty, because it is waterproof.

To begin with, I listed moisture-resistant putties to a friend:

• cement;
• plaster;
• acrylic;
• latex.

Then he talked about the features of each group, and he decided which putty is suitable for finishing the pool and bathroom, that the kitchen also needs a waterproof finish or protective aprons near the taps.

Moisture-resistant materials can completely repel water while still allowing walls to breathe. Most waterproof putties are not breathable. The room needs good ventilation. They are not recommended for use in living rooms.

Cement compositions are used as facade

Wall decoration in the bathroom with moisture-resistant putty

Finely ground Portland cement serves as the basis for most facade putties and plasters. It hardens perfectly in a humid environment and becomes stronger if it is watered for the first day. As additives that improve its properties, use:

• lime;
• sand;
• gypsum;
• polymers;
• fiber;
• glue;
• minerals;
• antiseptics.

The dry mix may contain 2 - 3 components and be made independently. Complex compositions are prepared on special equipment. They have minimal shrinkage, high strength. Stone and clinker tiles are used as facade cladding. By grinding or grouting, bring to a surface suitable for painting.

For interior work, cement putty is used in damp and non-residential premises. Under tiling, it is applied to the reinforcing mesh.

The lack of cement mortars in low vapor permeability. They are not recommended for use in the decoration of the walls of living rooms.

My friend and I used cement putty when finishing the basement and facade. Decorative plaster and paint fit perfectly on it. On the foundation there is a stone cladding on an adhesive basis.

Gypsum with polymers and hydrophobic additives is able not to absorb water

Everyone knows that gypsum absorbs water, swells and collapses. Manufacturers have found ways to make it resistant to moisture. Putty as additives has polymers and hydrophobic substances. They bind the gypsum and it becomes resistant to water.

Antistatics and antiseptics do not allow fungi and bacteria to develop in a wall covered with gypsum composition. At the same time, gypsum retains the ability to maintain an optimal microclimate. It absorbs excess moisture from damp air and releases it when the room becomes very dry. Cement and latex don't.

Finishing with moisture-resistant putty yourself

Vadik decided that gypsum putty would be suitable for the kitchen. There is little dampness in it, only during cooking. Most of the steam is taken by the hood. For safety, in addition to the apron over the tables, a friend decided to install glass on the walls near the taps, protecting it from splashes.

It was decided to finish the pool with a cement mixture and cover it with water repellents. This guaranteed complete waterproofing and made it possible to make a beautiful glass mosaic finish.

Acrylic putty for facades and interiors

Acrylic putty has a wide application, it is produced:

• for outdoor work;
• for interiors;
• damp rooms;
• decorative.

Various components give it the necessary qualities. Usually it is produced in white for painting. Partially decorative putty is tinted during manufacture or in large stores with special machines. Covered with mineral and acrylic paints.

Acrylic varnish combined with gypsum is used as a moisture-resistant putty. They make it on their own to seal small cracks and gaps around pipes.

I prefer ready mixes. My friend likes to experiment, and when repairing with his aunt, he made a plaster composition on acrylic varnish. He added talc and dry CMC to it. It failed to polish the surface.

Latex mixture is used only inside buildings

Moisture-resistant putty for wall decoration

Latex putty is plastic. It can be applied to walls that continue to deform during shrinkage. It does not peel off on flexible elements of light floors. Coated with a mineral primer, the latex mix bonds well with paints. When dried, a protective film forms on the surface. It makes the wall glossy. The paint lays down evenly and retains its shine for years.

Despite the ability to repel water, latex putty is not used outside. When exposed to UV rays, it becomes brittle and collapses. Does not withstand the elastic composition and low temperatures. When cold, it loses its plasticity and shrinks.

But in rooms with a constant temperature until the next repair will remain unchanged. For 20 years, it retains a glossy surface. Consumption is small. The optimal layer thickness is half a millimeter. For textured decor is not used.

The fungus under the latex putty does not start. It contains a large number of antiseptics. Therefore, it is often used for finishing damp corners in rooms.

Wall preparation

We putty the walls with a moisture-resistant mixture

Wall preparation is standard. The surface should be free of dust. Then the cracks are closed with the fixation of the sickle mesh. Moisture-resistant putties are applied in a thin layer. If the irregularities are large, then the number of coatings can be up to five.

It is desirable to coat the surface and each layer with a primer twice. In this case, the direction of the brush or roller should be perpendicular.

Modern renovation is unthinkable without the use of new materials developed on the basis of artificial components. When finishing rooms with a high level of humidity, special mixtures are used that protect surfaces from destruction, the formation of fungus and mold. Moisture-resistant putty occupies a special place among bulk building materials.

Characteristics and properties of moisture resistant putty

The dry mix used to create a moisture-resistant putty contains special synthetic components. Thanks to these additives, a coating is created that prevents:

• various kinds of leaks;
• release and accumulation of moisture;
• penetration of water droplets into the main surfaces;

The use of moisture-resistant compositions allows you to save the building structure and create favorable conditions for the functioning of the premises itself and the comfort of people.

Moisture-resistant putty refers to high-strength building materials. In addition to the waterproof effect, it has durability and reliability. Manufacturers guarantee the safety of the coating with such putty for at least 20 years.

It is resistant to changes in air temperature and does not respond to rising and falling degrees. This property allows you to securely hold the finish coating, which is used as a tile or mosaic.

Types and compositions of putties

Depending on the nature of the finishing work and the characteristics of the room, different types of waterproof putty are chosen.

• The cement mixture is based on Portland cement. This material is durable and reliable, which is especially important for wet rooms. When interacting with water, its properties improve. To make the powder composition even better, crushed marble chips, artificial plasticizers and hardeners are added to it. All these components give putty special performance characteristics. Since this mixture has a dark gray color, it is used for starting finishing of brick walls and concrete floors.

• Gypsum putty with polymer components has excellent water resistance. Synthetic elements in it are necessary to be able to work with such a mixture for a certain time, since natural gypsum quickly hardens and turns into crumbs. This seals the seams and joints between individual parts and elements of the building structure.

• Acrylic waterproof putty is a fully synthetic mixture specially created by scientists for finishing wet rooms. It is used as a finishing coat when leveling walls in bathrooms and kitchens for painting or wallpapering. With the help of this composition, designers decorate surfaces by drawing a pattern on a wet layer of putty. It is a durable, practical and crack-resistant material. Polymer products include latex putty, which has the same properties as acrylic.

• Oil-adhesive putty, consisting of glue and drying oil, is widely used in wet areas to eliminate cracks and other defects in the bases. It is sold in paste form and is initially ready for use. This material is intended for finishing walls and ceilings that will be painted or tiled.

Whatever the type of putty, it should dry quickly, hold firmly on the surface, create a smooth and smooth coating to the touch. It should not absorb water, repelling it. For the bathroom, putty with moisture-resistant properties is an indispensable material.

How to use moisture resistant putty

Most manufacturers of building mixtures produce dry formulations that must be diluted with water before use. How to do this is written on the package. If you strictly follow the instructions, you can get a guaranteed excellent material for finishing walls and ceilings in the bathroom or shower.

• Moisture-resistant cement-based putty is an excellent mixture for starting finishing in the bathroom. A thick mixture is applied to a pre-prepared brickwork or concrete base in a thick layer and carefully leveled with a facade spatula. It reliably hides the defects of the base and allows you to create an absolutely even coating.

• When the primary layer is completely dry, it is primed with a liquid composition, the liquid is allowed to soak in and the finishing layer of putty is applied. It should be like a paste that will smoothly cover the base.

When leveling walls in bathrooms, a special waterproof putty for the bathroom is usually used. Unlike other materials, such a composition does not lose under the influence of moisture, but, on the contrary, gains strength, which significantly increases.

In our article, we will describe the main features of moisture-resistant putties, as well as analyze all the nuances of their use in bathrooms.

Finishing material

Putty requirements

When deciding which putty to choose for the bathroom, you need to take care of meeting the basic requirements:

• First of all, the material must be moisture resistant. This means that both during the polymerization process and during further operation, the mechanical characteristics of the composition used should not decrease under the influence of moisture.

Note! This requirement is true even if the leveled wall is hidden under the finish.

• Secondly, after polymerization, the putty layer should not be subjected to intense temperature deformations. This is due to the fact that tile is often used as a finish, and if the base is too “movable”, then sooner or later the lining will begin to fall off.
• Thirdly, the material should be as durable as possible. The optimal service life of a leveled wall starts at 20 years, and it is this figure that you should be guided by when choosing a mixture for work.

All these parameters must be taken into account without fail, because high-quality moisture-resistant putty for the bathroom is the basis for the entire finish.

Features of the most popular funds

If we talk about the compositions used for this purpose, then the characteristics of most of them are quite similar:

• High-quality Portland cement is used as a binder. The use of this material is fully justified: with regular moistening, especially in the first months after application, the composition gains much greater strength than when dried at normal or low humidity.

Note! You will curse this feature in 25 years when you clean the wall for the next repair. However, there is no guarantee that this will be necessary!

• As a filler, clinker chips, sifted sand, ground marble, gypsum, etc. are used. To facilitate application and extend the service life, hardeners, plasticizers, and sometimes pigments are also introduced into the composition. Painted putties can be used for self-finishing, i.e. without the use of finishing materials.
• An alternative to cement compositions are putties with a polymer binder. The most popular today are water-dispersed compositions based on liquid acrylic or latex with the addition of marble grain.
• Like cement, these compounds are not at all afraid of moisture either during application or during further operation. However, the high price and a relatively small (albeit expanding) assortment have so far reduced the popularity of polymeric materials.
• Another trick when leveling the walls in the bathroom for tiles is the use of facade mixtures. According to their characteristics, they are almost ideal for use in high humidity conditions. Well, we can easily mask the coarse-grained texture with tiled lining!

As for gypsum leveling mixtures, in the name of which there is a mention of moisture resistance, then you should not use them in the bathroom. They, of course, resist moisture much better than traditional gypsum putty, but in the bathroom they will lose to both cement and polymer composition.

Leveling the walls in the bathroom

Surface preparation

So, we chose putty (cement or acrylic). Now we need to qualitatively apply it to all surfaces. How to do it yourself, we will now tell.

As in any business, success largely depends on the quality of the preparatory work.

In order for the leveling compound to adhere firmly to the surfaces, it is necessary to properly prepare the base:

• Firstly, either along the plaster layer, or along the leveling sheathing made of gypsum board or moisture-resistant boards. In any case, we will have to remove the remains of the old finish (tiles, cladding) from the walls and clean the surface.
• To facilitate our work, we make a rough leveling before puttying. Slots can be filled with a moisture-resistant sealant or cement mortar, and large irregularities (concrete swells, protruding pieces of gravel, rebar) can be knocked down with a perforator.

• Further, the instruction recommends disinfecting the wall. The warm and humid environment in the bathroom is ideal for bacteria and fungi to thrive. To avoid the appearance of pathogens, we impregnate the leveled surfaces with an antiseptic.
• The last step is the primer. For the bathroom, the ideal solution would be to use a penetrating composition based on liquid acrylic. Surface primers are not suitable, as they form a smooth layer that reduces adhesion.

Advice! For drywall bathroom cladding, deep penetration mixtures with a polymer binder also provide additional waterproofing.

Apply the primer with a brush to all treated surfaces. After the composition has dried, we proceed to leveling.

Layering

To create an even layer on the walls of the bathroom, suitable for further cladding or painting, proceed as follows:

• We put the first part of the prepared material into the recesses of the wall, as well as into irregularities lying below the general level (it is convenient to check this with a long rule). Level the mass with a spatula and let it dry for several hours.
• We process the applied putty with a primer and dry it again. The better the liquid is removed from the base layer, the more reliable the adhesion will be.

• Apply the final layer of leveling material. For processing large areas, it is convenient to use a trowel about 50 cm wide. It is better to process small bathrooms with a spatula - this way there will be less marriage.
• We smooth all the walls until a perfectly smooth surface is achieved. We do the same with the ceiling.

After applying the second, finishing layer, it is necessary to dry the entire surface with high quality. And in order for the drying process to be as efficient as possible, it is necessary to ensure a stable temperature and the absence of drafts. This is easy to do by simply closing the bathroom door.

But excessive moisture not only does not harm the cement putty, but also helps it gain strength. So there is no need to turn on forced ventilation.

Finishing

Now we need to prepare the putty walls for painting or cladding:

• First of all, processing must begin no later than three to four days after the alignment is completed. Otherwise, the cement will harden so much that no grinder will take it.
• Secondly, during processing, strictly adhere to safety regulations. Dust is enormous, so a hair cap, goggles, and a respirator are a must.

The alignment process itself is simple, although quite laborious:

• On a manual grater or electric grinder, we fix the abrasive mesh for finishing. Instead of mesh, you can use emery No. 80 or similar - as long as the grain is not too large.
• We process all planes in circular motions until the slightest irregularities are removed.
• In the course of work, we control the state of the surface using a level and a rule.
• After grouting is completed, we remove the dust formed during the work.
• At the last stage, without fail, we prime the walls and ceiling with a penetrating compound. This composition acts as a binder between all layers of putty, and increases the strength of the base for decorative finishes.

Conclusion

Moisture-resistant putty for the bath is used in almost the same way as any other material. However, the properties of the components that make up its composition make it possible to use it in conditions of high humidity. At the same time, the quality of alignment does not suffer at all, especially if all the work is done according to the rules.

The video in this article will help you deal with some of the nuances, and you will approach the repair with high-quality theoretical training!

Premises with a high level of humidity make higher demands on putty materials than dry ones. Facade mixtures with high performance characteristics are well suited to such rooms. Moisture-resistant putty for a bath or other room allows you to form a coating that is resistant to the destructive action of water and prevents the appearance of mold. Applied according to the technology for painting (or wallpaper, Venetian), it contributes to the creation of a durable, beautiful design of the room, an example of which is shown in the photo below.

Types of putty for wet rooms

The construction market is replete with putty materials that have different properties and composition. Various subsequent types of finishing are also used. Regardless of this, putty for a bathroom or other highly humid room should be:

• moisture resistant, so that the created coating does not collapse (do not get wet) during operation from direct exposure to water or its vapors;
• durable (at least 20 years);
• resistant to temperature fluctuations: do not shrink and do not expand with drops.

Facade varieties meet all the above requirements. The photo below is one of the many brands of such material.

In addition to these basic criteria, when choosing a material, one should take into account the method of further decorative finishing. For example, the formed coating for painting should not shrink, so the putty is selected with this property.

Waterproof putty according to its purpose is divided into the following types:

• finishing, used for finishing surfaces;
• leveling (starting), designed to hide defects (holes, minor irregularities);
• universal, which combines the functions of the first two types.

By readiness for use (release form), the putty is divided into:

• dry mixes that must be diluted with water before work;
• ready solutions.

Products suitable for use in humid conditions must be marked on the label (indication of moisture resistance).

Products are produced in various packaging: plastic buckets and bags. The container contributes to the preservation of the original properties of the material for a long period. It is easier to work with ready-made formulations, but they are also more expensive than dry mixes. When buying, be sure to pay attention to the expiration date of the material so as not to purchase an expired product of inadequate quality. This will allow, subject to the application technology, to obtain an excellent result.

Composition classification

The division of putty for wet rooms by incoming components is presented in the table below.

When choosing one or another type of finishing material, the following features should be taken into account:

• cement-based mixtures for walls in the bathroom (other wet rooms) are resistant to mechanical stress and moisture, but the coating created from them is subject to slight shrinkage;
• cement compositions are well suited for ceramic tiles;
• the finishing layer of gypsum putty does not shrink, dries quickly, but does not tolerate the effects of increased moisture and temperature changes;
• polymer products have a high degree of plasticity, do not change their volumes after application and drying, and are considered an excellent option for leveling surfaces;
• oil-adhesive mixtures are considered obsolete material due to lower performance (than similar products), they are used to repair utility rooms in the absence of high quality requirements for the result.

The photo below shows acrylic putty in a plastic bucket - a type of polymer composition.

Polymer putty compositions are more convenient to use than other of the considered analogues. The quality of the coating formed from them is also higher. But the higher cost of such a building material prevents their wide distribution. Many experts do not recommend the use of gypsum mixes in wet rooms, despite the presence on the label of the appropriate marking.

Material handling technology

Putty for the bathroom for painting or other design method is applied to the work surfaces only after they have been pre-treated. The process itself does not require expensive equipment and special tools. The technology allows all operations to be performed independently without the involvement of specialists. Only work needs to be approached carefully and without haste.

Preparatory activities

Before preliminary work, you should prepare the necessary tools and purchase materials so as not to be distracted and not to waste time on this matter in the future. It is necessary to purchase putty, based on a preliminary calculation. To do this, proceed as follows:

• calculate the area of ​​the working area;
• according to the curvature of the surface, the average thickness of the leveling layer is estimated;
• calculate the volume of the required material, and by density - the mass.

The primer and putty composition should be purchased with a 10% margin.

You will need the following tools and devices for work:

• several spatulas of different sizes;
• a set of containers for mortar and water, a primer;
• perforator and nozzles to it;
• rule;
• level;
• metal brush;
• roller and brushes;
• grater and sandpaper;
• ladder.

You can also use a construction mixer so as not to smear the puncher, and when working, you should use skin protection (gloves, overalls) and breathing (respirator). It is worth making sure that the solution does not accidentally get into the eyes. In this case, immediately wash it with clean water.

Other tools may be needed under unforeseen circumstances, for example, a grinder. The necessary set for puttying the walls is assembled in the photo below.

The preparation of the walls in the bathroom (in a wet room) takes place in the following sequence:

• remove the old finishing coating that has completely become unusable, or only its defective areas;
• existing protrusions (nodules, stones or metal fragments) are dismantled flush with the base plane;
• the working surface is cleaned of dust and other contaminants (oil stains, fungus);
• the existing large damages (hollows, cracks) are filled with cement plaster mortar, and if necessary, they are completely leveled;
• treat the surface with an antiseptic to prevent mold;
• primer cover the walls;
• waiting for the coating to dry.

Mounting foam can be used to fill joints (in panel structures) and deep cracks. The moistened work surface is pre-dried. Places with mold are burned with a blowtorch to destroy microorganisms that have penetrated deep into the base.

The quality of the base preparation depends on how the putty layer will adhere to it and, therefore, the finish will look like. So, for painting, the surface must be leveled perfectly.

Applying putty

After the preparatory manipulations, the walls begin to putty. The process consists of several stages:

• determined with the number of applied layers;
• when using dry mixes, a solution is prepared: the material is poured into the container and the required amount of water is added, everything is stirred until a homogeneous paste-like mass is obtained;
• with the help of a spatula putty is applied to the surface, and in large areas they use the rule, having previously thrown the working composition onto the base;
• if necessary, apply the next layers after the previous levels have dried;
• prime the surface;
• after the time required for drying, the final layer is formed;
• sanding the dry finish.

The application of the solution with a spatula is shown in the photo below.

In the process of work, the evenness of the formed coating is constantly monitored. Removing the corners speeds up the use of the corner trowel. For well-plastered and leveled walls, you can use only the finishing mixture. The ideal option is to prime each applied layer.

Working with putty materials is quite simple. Compliance with technology leads to the achievement of a qualitative result. The following tips also help:

• to improve the mechanical strength of the coating, it is reinforced with a mesh;
• the solution is applied in thin layers (no more than 3 mm each);
• the best option for drying the created coating is natural, because the use of heat guns and heaters of other systems can lead to cracks due to too rapid drying;
• with further staining or the use of decorative mixtures and wallpaper, it is better to add a pigment that matches the color of the final finish to the working solution (or use a ready-made desired shade);
• any facade putty is suitable for wet rooms ;
• the use of a finishing coating with increased moisture-proofing characteristics makes it possible to use even mixtures for dry rooms;
• work should be carried out at an air temperature of more than +15 degrees;
• under the paint it is required to grind very well, but for the tile it is not necessary.

It is not recommended to use compositions not intended for wet rooms. In the event of water intrusion, this can lead to detrimental consequences, up to the replacement of the entire finish.

Taking into account the nuances allows you to do the job better, and often spend less time on it. A result similar to the view shown in the photograph will delight for many years.

Waterproof putty for the bathroom, or rooms with high humidity, is made by many manufacturers in finished form or requiring preliminary dilution. According to the composition, four groups of this material are distinguished. Polymer compositions are considered the best option in terms of quality. They are followed by cement-based mortars, but polymers are less common because they are more expensive.

All facade mixtures are well tolerated both by moisture and temperature changes. The technology of work with putty in wet and dry rooms is similar.

Putty for wet and dry rooms is described in the video below.

Moisture-resistant putty is used at the final stage of finishing the room. It is mainly used for finishing the surface of the wall and can be used both inside and outside the building. Its use in wet rooms requires a special approach, so a special composition is used there, which has all the necessary properties. In addition, high humidity leads to the appearance of mold, and in order to avoid such troubles, you need to competently approach the choice of finishing materials. Depending on temperature fluctuations and humidity levels, you can choose the perfect option for repairing a room.

Characteristics of moisture resistant putties

cement-based

All moisture resistant pastes contain one main component - Portland cement. This material is obtained by combining crushed gypsum and clinker. This powdered substance is stored in a dry form, and before use, a certain amount of water must be added to it and mixed to the desired consistency.

In liquid form, waterproof putty does not last long, since almost immediately after adding water, it begins to harden. If water gets on such a paste composition, this only enhances the process of hardening the solution. For those who are starting to work with putty mixtures for the first time, we recommend that you do not make large batches so as not to rush to use them quickly.

All professional technicians use a moisture-resistant cement-based paste to repair facades. In addition, it is also used for interior decoration of the house, in particular, in bathrooms where moisture is present. Due to its unique composition, any wall surface will be protected from moisture and have a finished look.

Gypsum based

An alternative to cement mixtures is gypsum moisture-resistant putty. The advantage of this material is that its consumption will be less than the use of a cement-based mortar. Despite the fact that the gypsum composition hardens rather quickly, it does not form cracks.

Gypsum putty was created thanks to the gypsum-purcalan composition. It is designed specifically for the repair of wet rooms, so it has found a good response from professional specialists. Be sure to consider these components when buying putty pastes.

However, gypsum putty can only be used under certain conditions. Also, experts recommend using a moisture-resistant gypsum-based paste in which Portland cement is present, otherwise its use in wet areas will be a big question.

Finishing with moisture resistant putty

Waterproof paste is applied to the walls in a standard way. When working with it, a conventional tool is used. Depending on the presence of depressions and irregularities, both wide and narrow spatulas are used. Complete drying of the putty mixture occurs a day after application.

For finishing facades, waterproof putty is often used, which contains additives based on pigment dyes. This allows you to get a better painting of the surface of the facade, since paint and putty have the same composition of dyes.

Waterproof putty with the addition of dyes is also used for interior work. This composition is contained in the finishing putty, which creates a solid foundation for further painting of the wall surface. This method is also economically beneficial, as it significantly reduces the cost of paint.

Do not forget that the finish is made only on a primed and well-dried surface. Repairs should be carried out in dry rooms in order to obtain a good quality of work.

Bathroom finishing

Most often, moisture-resistant paste is used for the room. Given the high humidity of the room, it is possible to obtain a high-quality finish through the use of high-tech mixtures. Modern putty mixtures are based on plasticizers and hardeners, which allow you to get excellent performance in working with wet rooms.

Immediately after applying a layer of mortar, the entire surface of the wall can be slightly moistened. This will allow the composition to harden even more, since moisture will have a maximum effect on the composition of the waterproof mixture.

Additionally, clinker or marble chips can be used as a filler. Such a solution will allow you to get, which will also have the properties of moisture resistance.

Putty is usually applied in several layers. At the first stage, all rough bumps, depressions, cracks are eliminated, thereby creating the basis for the next, finishing layer. In the second stage, an elastic mixture is used, which prevents the penetration of moisture. Moisture-resistant mixtures also include preparations that prevent the appearance of mold.

Before each application of the solution, the surface must be primed, and then allow time to dry well. If it is planned to install the wall with ceramics, a special waterproofing adhesive will be used as an additional component for the primer.

Where is moisture resistant putty mixture used?

For outdoor finishing, waterproof putty is used for facades of buildings, outdoor pools and shower rooms. This protects the walls from moisture, the appearance of various types of mold. The repair technology is the same in all cases, first the first, starting layer is applied, then the finishing one on a waterproof basis.

For interior work, it is used in bathrooms, kitchens, cooking departments, baths. Despite the fact that the interiors have high humidity, the composition of the putty does not change. As changes, there can only be fillers that complement the base of the mixture.

Experts also recommend the use of waterproof-based putty in rooms where moisture is acceptable. It can be a kitchen or other cooking rooms. Despite the abundance of all kinds of exhaust devices, a large amount of steam can appear in the kitchen, which will lead to an increase in the level of humidity. Such frequent drops can adversely affect the walls, which will not have adequate protection.

Baths or showers have a maximum level of humidity. It is necessary to apply finishing in such rooms strictly in accordance with standards and technologies. In addition, before starting work, it is necessary to completely dry all the surfaces of the wall, treat them with antifungal drugs, and then proceed with the repair.
