The best deep penetration primer. How to choose the right primer for different surfaces

Not a single stage of construction or repair work Porous or old substrates should not be treated without a primer. It is designed to ensure good adhesion, strengthen the base, regulate absorbency and increase the service life of the finish as a whole. So, primer deep penetration- which is better? We'll figure out.

Deep penetration primer for walls - a multi-component composition, including:

1. Water, which occupies the main share in the composition. Used to dilute the soil and bring it to the desired consistency.
2. Acrylic resins acting as the main binder;
3. Polymer components responsible for the penetration of liquid as deep as possible into the base.

A good deep penetration primer optionally contains:

1. antiseptic additives necessary to protect the surface from the risk of mold;
2. silicone agents characterized by the ability to repel water;
3. latex designed to improve adhesion of the treated substrate and subsequent finishing.

If it contains auxiliary additives, the deeply penetrating primer becomes universal.

Application of deep penetration primers

The scope of application of the primer is excessively absorbent and porous substrates (concrete, plastered and plastered surfaces, drywall, gypsum, etc.), including old and crumbling surfaces.

Due to availability acrylic resins Penetrating primer perfectly saturates the surface and penetrates into the deeper layers. Thanks to polymer additives the soil, as if through capillaries, enters the very thickness of the plane, binding the surface into a monolithic and reliable foundation.

The process of water absorption (evaporation) is accompanied by the convergence of resin granules, as a result of which they stick together into thread-like formations that penetrate the surface.

Specifications

The deep penetration primer, the characteristics of which are presented below, differs slightly in composition.

That is, manufacturers can use some components in different concentrations to enhance or reduce the effect of a particular property. However, most soils have fairly similar parameters:

It is worth noting that deep penetration primer, the average consumption of which is 150 g/m2, can be consumed at 400 g/m2. It all depends on the absorbency of the base. Its color varies from light white to colorless with yellowness.

Application is carried out in several layers, at intervals of at least an hour. To be sure that the soil is dry, it is necessary to soak the base for 24 hours and only then proceed with subsequent finishing.

Advantages of soil

A deep penetration primer, the characteristics of which indicate its versatility, is endowed with a number of advantages. The main one is the unique ability to penetrate into the deepest layers of the surface.

Thus, even an old and loose base can be turned into an excellent base for the most modern finishes, without fear for the durability of the latter.

Making its way deep into the base, the deep penetration primer for walls strengthens and strengthens them, which allows them to increase their service life.

Sufficient vapor permeability of the soil turns the surface into a breathable one, promoting air exchange. And the presence of fungicidal additives reduces the likelihood of fungus formation to almost zero.

A deeply penetrating primer, providing air exchange, isolates intracavity pores using silicone. That is, the base also becomes waterproof. The overall wear resistance of the layer to both mechanical and chemical influences also increases.

Thanks to its ability to level out the porosity of the base, penetrating primer significantly reduces the consumption of decorative materials. finishing materials, in particular plasters, putties or paints.

The work is not accompanied by toxic odors. It is very easy to apply the composition. Also good primer deep penetration is not only non-toxic, but also non-explosive.

Comparison of soils from different manufacturers

Today, penetrating soil is produced on behalf of many domestic and foreign manufacturers. The following will tell you which compositions have more universal technical characteristics. comparative analysis presented in the table.

Which deep penetration primers are better is unmistakably demonstrated by the penetrating ability of the compositions. The higher this indicator, the better the surface will be strengthened and its absorbent properties will be regulated.

This is especially important for extremely absorbent substrates. For moderately absorbent soils, it is enough to purchase soil with a penetrating ability of 3-5 mm.

Available from different brands, deep penetration primers have approximately the same consumption, so basing the choice on this value is irrational. It is worth remembering that it is the porosity and type of base that play a decisive role in soil consumption.

The purpose of the composition, its components and the reputation of the manufacturer are several more criteria according to which the soil should be selected. Finding out what a deep penetration primer is and which one is better, you can come to a certain conclusion - one that, along with excellent penetrating parameters, will create a protective water-repellent layer, level the surface and increase its adhesion.

Deep penetration primer - which is better, video

They help strengthen loose substrates, reduce the absorption of porous surfaces, and increase the adhesion of glue or mortar. The primer will prevent plaster and other finishing materials from peeling off and protect against mold and mildew. For maximum effect you need to choose the right soil.

Selecting a primer based on operating conditions

Which primer to choose for exterior work

For outdoor work, it is necessary to choose frost-resistant compounds. They will not crack and will not cause peeling of the finishing material when low temperatures. In this case, it is better to choose a deep penetration primer. Typically these are silicate or acrylic primers for mineral surfaces. This material penetrates deep into the base, sealing the pores and preventing moisture from absorbing into the surface. As a result, even during sharp frosts, ice will not form in the thickness of the wall, which is the main cause of destruction.

Which primers are best for interior work?

For interior work choose a primer that is odorless, such as latex or acrylic. Please note that special options are available for wet areas and wood. compositions with antiseptics.

Selecting a primer by surface type

Which deep penetration primer is best for concrete?

Any designed for absorbent substrates. It will increase surface adhesion to mortars, paints, glues. This can be a universal acrylic or alkyd primer. Special compositions “Betonokontakt” liquid are also suitable Pink colour with quartz sand, which makes the surface rough.

Which deep penetration primer is best for wood?

Oil compositions are well suited for treating surfaces for painting, including for preparing previously painted substrates. Can be applied acrylic primer in several layers, it will strengthen the base well and give it hydrophobicity. Many manufacturers indicate on such primers: “for wood.”

Which deep penetration primer is best for the ceiling?

You can choose any composition for mineral bases, including “Betonokontakt”. The ceilings in most rooms are reinforced concrete slabs floors that show virtually no adhesion to finishing materials. The primer helps prevent the plaster from peeling off.

How to choose a primer for drywall

Here, deep penetration formulations are not needed, because the base has minimal absorbency. You can choose a universal acrylic primer; it is perfect for drywall. It would be good if the material contained antiseptics.

Selecting a primer by type of finish

Which primer for walls under putty is better?

Pre-impregnation of the base will help distribute the solution more evenly and thinly over the surface. It will prevent drying out and cracking. If the base is concrete or Brick wall, you can choose “Betonokontakt” or another mineral-based composition.

What primer to use before laying tiles

The composition should be intended for wet rooms, because tiles are usually laid in bathrooms and kitchens. When choosing a specific soil, be guided by the type of foundation. It is important that the impregnation is suitable for the surface, because almost all primers exhibit good adhesion to tile adhesives. The impregnation must contain fungicides to prevent fungi from growing under the finish.

Which primer for walls under wallpaper is better?

You need to focus on the material from which the canvas is made. For thin paper or textile wallpaper Acrylic or latex primer is suitable. These impregnations are odorless and do not appear on the surface. yellow spots. For vinyl wallpaper, vinyl acetate primers are chosen. If the wall is covered with plasterboard, then a single application of primer is sufficient. For mineral surfaces, a deep penetration composition is suitable.

Which primer to choose: conclusions

In general, to choose a primer for wallpaper and any other type of finish, you must first pay attention to the operating conditions and type of base. For finishing the façade, use only frost-resistant primer, otherwise the plaster or paint will develop cracks very quickly.

For interior work perfect option- water-based compositions. They do not cause allergies and do not contain harmful substances. Mineral, old concrete and wooden surfaces require a deep penetration primer with a strengthening effect. For drywall and new concrete, a compound for low-absorbent substrates is required. Always pay attention to the manufacturer's recommendations, which are indicated on the label for each material.

Room decoration is one of the most important components good repair, therefore it should be carried out only with high-quality and effective means such as deep penetration primer.

Due to the fact that there are many types of them, it is always difficult to determine which primer to choose, which one is better and how it should be applied correctly so that the finishing of the surface of the material is carried out successfully.

Purpose of the primer

The use of a deep penetration primer is required for finishing insufficiently dense and loose wall surfaces. This can be done due to the presence of a binding component in its composition, which contains microscopic particles.

When applying a primer, they all get deep into the material and begin to stick it together, after which it will be more durable. Also, a primer with deep penetration has an antifungal and antiseptic effect on it.

After which it is covered with some protective film, which subsequently prevents moisture from penetrating into the material. The primer is well suited for such types of bases as: foam concrete, plasterboard, wood, plaster, brick, aerated concrete.

It can be used both for finishing surfaces inside and outside the house..

Properties of soil for walls

Deep penetration primer has the following properties:

• color. A combination of milky, white and colorless shades;
• The primer has no frost resistance;
• material safety. The components of the primer are not explosive, fire hazardous or toxic;
• the penetration depth depends on the degree of porosity of the material and can reach 5 – 10 mm;
• largest particle size – 0.05 microns;
• operating temperature is 40° – 60°;
• antiseptic properties are characteristic of the primer;
• drying times. Each coat of primer should be applied in stages with a time interval of 1 hour. In order for the primer to dry completely, you need to wait 1 day if the air temperature is at least 20 ° and the humidity is not less than 60%;
• The ambient temperature should be 5-30°.

Advantages

When using a primer to finish concrete, air exchange occurs and at the same time does not isolate the pores inside it. It is characterized by significant stability and can withstand up to 5 cycles of defrosting and freezing down to -15°. The finishing material connects well with each other.

Wall plaster is necessary step apartment renovation work. learn how to level walls with plaster.

Plaster increases the thickness of the walls, which has a positive effect on their strength. information about how long it takes for plaster to dry on walls.

Any residential and non-residential premises need to provide heat. - the key to high-quality and reliable heating.

Reduces the amount of materials used for further finishing.
By choosing the best primer for deep penetration, it will ensure good water resistance and vapor permeability of the surface. Due to the presence of antiseptic properties, fungus and mold do not form on the surface of the material.

Penetrates deeply into the material and adheres to it. When the primer dries, a matte layer forms on the material. The walls become stronger and thus cracks do not form in them. Adhesion increases. You can prevent the formation of stains and streaks on the surface. Dust is removed from the surface of the material.

Types - how to choose the right one

Its main component is polymer. A very popular primer of this type is. It can be used to finish: brick, concrete, wooden surfaces.

It can be made on a water basis and its main advantage is quick drying and the absence of odor of the liquid.

Quartz primer consists of sand.

It is well suited for improving adhesion even if walls are finished with paint or plaster. It is completely harmless to use and at the time of its use it is necessary that the surface of the material is wet.

It can be used if the walls are treated with brick or concrete.

At the end of its application, the wall will be dry after 2 hours. Its binding component is cement.

Its components are phosphorus and zinc chromate, which prevent the appearance of rusty particles on the surface of the material.

This primer can be used for finishing surfaces made of wood, glass, metal or ceramics, but in no case should it be used on walls made of plasterboard or concrete.

It is also important to take into account that such a primer takes a long time to dry even after some finishing works 12-15 hours should pass.

Antifungal or antiseptic

Antifungal primer for walls is used to prevent the appearance of fungus and mold on the walls and is divided into a regular antifungal primer, which is intended to prevent their appearance, and a strong antifungal primer.

If you use a regular antifungal primer, then it will help prevent fungal formations from occurring on the walls. It also increases the level of adhesion of materials and holds them together well.

Universal for deep penetration

Universal primer for deep penetration.

It should be used to destroy dust accumulations on the surface of the walls and make them denser.

In order to test the effect of this primer, you must first glue something to the walls and then try to tear it off.

The material cannot be torn off from the surface on which there is a primer, and from the surface where there is no primer it will easily come off.

In addition, if you apply to unprimed walls tiles, plaster or any other material, within one year it will begin to fall off, even if you used high-quality glue.

It is worth remembering that the adhesive for, tiles in and tiles from differ from each other in their properties and characteristics.

With its help, you can glue to the surface of walls or ceilings something that is impossible when using other types of primers with deep penetration, each of which is better in its own way. While applying the concrete contact primer, you can putty the walls that, for example, can be painted.

Concrete contact primer is an adhesive substance that contains filler in the form quartz sand. It promotes education rough surface material onto which it is applied and then anything can be glued to it.

Overall, this is a fairly good primer for deep penetration and no matter which one is better, they will all withstand heavy loads and are suitable for laying tiles or plastering walls.

How to do it yourself?

Before starting finishing work, you can buy a good deep penetration primer in a store or make it yourself. To do this, you will need the following materials: 200 g of soap, 3 kg of slaked lime, 100 g of oxol and 7 liters of water.

Steps for preparing the primer manually:

1. Take a container and pour 3 liters into it boiled water .
2. Rub the soap.
3. Place soap in hot water and add drying oil there.
4. Take another container, pour 4 liters of boiled water into it, put lime in it and mix the two solutions.
5. The mixture resulting from the above steps should be mixed well and filtered.
6. Once the mixture has cooled, you can begin to apply the primer.
7. After this you need start calculating the amount of primer used. Its application is based on the type and type of primer mixture.

Rules for diluting ready-made soil mixture

• You need to use an acrylic mixture to finish walls that are covered with putty or plaster;
• dry waterproof primer must be diluted in water in a ratio of 1:4;
• if an alkyd primer is used, it should be diluted with a solvent or replaced with xylene or solvent in a 1:1 ratio;
• a one-component primer must be diluted as required using a solvent, drying oil or water according to the instructions;
• if you have a two-component primer, you must first add a hardener and thinner to the mixture;
• alkyd as the best primer for deep penetration into walls must be diluted with a solvent in a ratio of 1:1;
• It is recommended to first mix the dispensed aqueous mixture and place it in a separate container, and then add water to it.

Application technology

After determining which deep penetration primer is worth using, with which ones and which of them is better, you need to know how it will need to be applied to the surface:

It is necessary to check the air temperature so that it is not less than 5 g and does not exceed 30 g. The air humidity should be about 75%.

Purchase a brush, primer tray and roller along with a telescopic handle in advance. Next, you should wash off the whitewash layer with water and remove the old wallpaper from the walls. In those parts of the wall in which the paper remains, it is necessary to moisten it and gradually remove it using a spatula.

Pour some soil into a tray special for this purpose. Take a brush, roller and pick up primer. At the same time, you should pay attention to ensure that the liquid does not run off and splash in different directions.

The wall must be gradually and carefully coated so that there are no dry parts or drips on it.

The primer mixture should not drain from it either. Use a brush to coat hard-to-reach parts of the wall. The best primer used for walls for deep penetration purposes should be applied in layers.

After completely coating the wall, you need to wait 2-3 hours for the first layer to dry and only then apply the second.

After finishing it, you can start painting, laying tiles, and wallpapering.

• no need to dilute the entire mixture at once. Only part of the primer will be enough;
• before you start lubricating the walls, you need to ensure that the walls have a clean appearance;
• after the primer gets on parts of the clothing or the floor, you should immediately wash off the dirt and wipe it with a damp cloth;
• there should be no streaks of primer on the walls;
• wall finishing should be done using special protective gloves;
• Apply the primer in comfortable clothing.

Choice

You can buy a deep penetration primer for 200 rubles with a capacity of 10 liters. Also due to the fact that from building materials They make fakes quite often, you need to understand them well so that you can immediately determine which primer is worth buying and which one should be discarded.

To purchase a high-quality primer, you should adhere to the following rules:

1. When determining which deep penetration primer is best and which one to choose, you need to: pay attention to its manufacturer, which must have its own office or official website on the Internet, where you can send your claim if necessary.
2. You should not buy packages of primer if it is labeled by an unknown manufacturer.
3. It is advisable to buy primer only in its original packaging.
4. When purchasing a primer for the first time, when a person does not know what it should look like and is offered to buy it in a package that cannot be easily opened, it is better not to purchase this product.
5. In order to accurately know the primer per 1 m2, you just need to read the detailed information about it on the packaging. Its exact amount depends on the condition of the primed surface. As a rule, to carry out finishing 1 sq. m. 80-160 g of soil is needed.

Conclusion

Based on all of the above, primer is one of the most the best materials for wall decoration which has many advantages.

Thanks to the characteristics of the varieties of deep penetration primer, you can find out which one to choose, which one is most suitable and how to make it yourself at home or purchase it.

In order to finish walls using a primer, it is necessary to follow successive stages of its implementation and apply layers of primer after a certain time when each of them is completely dry.

Any surface must be primed before finishing; for this, a deep penetration primer is used.

Currently, there are many types of emulsions on the market, each of which is intended for certain types of work.

To correctly select the right deep penetration primer, you need to know its characteristics.

What types of primers are there and how to choose the right antiseptic can be found in this article.

Application of the mixture and its types

First you need to understand what the emulsion is used for, what role it plays in construction and what types of primers exist.

A brick wall or concrete base can be treated with a universal primer, but for other surfaces it is necessary to purchase a primer with additional components.

As for the composition of the deep penetration emulsion, it is almost the same, the only difference is in the concentration and special additives.

The main component in the primer is resin from acrylic material, and additional components simply enhance the depth of penetration and determine how long the primer dries.

The main types of emulsion are divided into several categories:

• Deep penetration acrylic primer designed for use on most surfaces. It can be used to work both on wood and on concrete surfaces. This type of primer can be called universal to a greater extent. A positive indicator is rapid drying, which will speed up the process of further work, as well as a large penetrating layer;
• Silicone primers are mainly used for facade works before application paint and varnish materials;
• deep penetration antiseptic primer is used to eliminate mold and mildew. As additional component this mixture contains a fungicide, which is a good antiseptic antifungal drug;
• To prevent corrosion on metal products, an epoxy mixture is used. It can be used when installing self-leveling floors;
• for metal surfaces you can use an alkyd primer mixture;
• a composition with aluminum components is used for complete wood processing;
• deep penetration primer, whose composition is based on alkyd solutions, is more suitable for processing wooden coverings And metal products. Use for gypsum plasterboard and plaster is not recommended, since this mixture forms a rough surface, which can complicate the process of long-term processing;
• silicate emulsion is recommended for highly porous substrates such as aerated concrete, gas silicate and brick;
• latex primer is mainly used on smooth surfaces which have small pores. By using such a primer, the adhesion of the base increases.

In order for a primer material to be ideally suited to a surface, it is necessary to take into account the area of ​​application, the conditions in which the mixture will be used, and the condition of the surface that needs to be primed - this will also determine how long the primer takes to dry.

A good combination would be the option where the emulsion and further finishing materials are produced by the same company.

The effect of the emulsion and its consumption

The action of the mixture occurs immediately as soon as the emulsion is applied to the base.

Upon contact with the coating, the emulsion begins to penetrate to a depth of ten millimeters; after the water evaporates, the adhesion reaction of the acrylic resins begins, resulting in a uniform layer.

How long the primer dries depends on the temperature and concentration of the emulsion: the more water added, the longer time drying out.

The consumption of deep penetration primer per 1 meter depends on many factors, but basically all manufacturers indicate the amount of consumption and area of ​​application on the packaging.

It should be remembered that for concrete coverings a deep penetration primer is required for concrete, then the consumption of the emulsion will be minimal, and this will also affect how long the primer will take to dry.

The scope of application of the emulsion can be very different - just like external conditions. If the work is carried out indoors, then a special deep penetration primer for interior work is used.

This composition is good for treating ceilings and floors in the room, but it is worth remembering that when high humidity rooms, it is necessary to use a deep penetration antifungal mixture.

A strengthening mixture is used to treat the floor, because it is the floor that bears all the maximum loads, and a well-penetrating liquid will provide maximum protection.

Further finishing work on the floor should be carried out after the surface has completely dried: how long the primer dries can be seen on the packaging.

Deep penetration primer for exterior use is used both for concrete surfaces, and for plastered ones.

Polystyrene mixture is mainly used for exterior work. When working with such an emulsion, personal protective equipment should be used, since polystyrene emulsion is highly toxic.

If the surface consists of a different material, then the solution must match the coating.

Technical characteristics and composition

For deep penetration primer, the technical characteristics are as follows:

• improving the moisture resistance of the base;
• resistance to sub-zero temperatures;
• strengthening loose surfaces;
• minimum primer drying time;
• good antiseptic;
• low consumption per 1 m2;
• increases adhesion between finishing materials and the base.

In finishing works, applying emulsion to the surface is one of important stages, since during further work the treated surface will help reduce the consumption of finishing materials and improve the quality of applying putty or other mixtures.

Sometimes a loose or damaged coating should be treated several times - this will allow the first layer to penetrate deeper, and additional application will strengthen the work surface.

Increased resistance to sub-zero temperatures applies mainly to materials that are used for outdoor work.

All types of mixtures contain almost the same components: only the difference in additional components distinguishes a universal mixture from an antifungal mixture or from an emulsion for wood and metal.

The deep penetration primer has the following composition:

• aqueous dispersion, makes up about 70 percent of all emulsions;
• acrylic resins, which act as a binding material;
• polymer additives that promote surface absorption and affect how long the primer takes to dry;
• fungicides that are used only for antifungal mixtures;
• silicone component responsible for the moisture resistance of the treated surface;
• latex, which helps increase adhesion.

There is a product on sale in which the percentage of water is much less than in the others - this composition is called concentrated.

Manufacturers recommend adding water before using concentrates. The presence of water in the concentrated solution will determine how long the primer will dry, and this will also reduce consumption by 1 m².

It would be better to dilute the concentrate in a one to one ratio.

Application area

The antiseptic is available for all types of coating, therefore, the scope of application is wide.

Brick, concrete, putty surfaces can be treated with any composition - the effect will always be positive, the only difference may be in the additional layer.

For exterior work, you should purchase a material with high adhesion and reduced sensitivity to frost, but sometimes primers are also used for interior work.

You can use a primer for outdoor work indoors, but you should take into account the fact that outdoor emulsions are highly toxic, so you need to work in a well-ventilated area.

Penetrating or universal primer is used for those substrates that have a porous surface and can absorb moisture.

Such a surface includes concrete or plaster, but metal surfaces it cannot be processed.

Basically, all types of primer have penetrating properties, hence the question “which deep penetrating primer is best for porous surfaces?” implies the answer: everything.

A deep penetration primer, the composition of which consists of aluminum additives, is used for treating wood coatings both outdoors and indoors.

Deep penetration antifungal primer is used in damp rooms and open spaces where fungus may frequently appear.

The fungicides included in the antifungal emulsion help prevent mold. In the case of existing fungus on the walls or ceiling, the surface should be treated with a special solution containing chlorine or regular white.

After mold has been completely eliminated and the surface has dried, an antifungal primer can be applied.

When using any type of mixture, you should remember that the emulsion penetrates not only into the treated coating: it can leave its traces on those surfaces where it should not, and damage furniture or other property.

To prevent the composition from getting into unwanted places, polyethylene or other protective measures should be used.

To use the primer emulsion in open spaces, it is necessary to choose dry and windless weather, which will help speed up the drying process and reduce product consumption, because external factor has a huge impact on quality.

Well-known manufacturers of primer material

When you come to the market or store, you can see a huge assortment of emulsions for primers, including: domestic producers, and foreign.

Russian manufacturers that are popular with builders include two brands – “Staratel” and “Lakra”.

Antiseptics from these manufacturers are much cheaper than foreign brands, therefore, for surface treatment large area You can get a primer from one of these companies.

Products of foreign brands such as Ceresit and Knauf are considered high-quality materials - their price will be slightly higher than that of domestic products, but such emulsions are well suited for loose surfaces and for those that need good adhesion. The emulsion of these companies is good for use on concrete.

Depending on the trademark and the type of mixture will depend on the quality of the surface being treated, the material consumption and how long the primer will take to dry.

Therefore, in order to properly prepare the base for subsequent finishing work, it is necessary to properly prime the coating.

To do this, you need to purchase a quality product (preferably from well-known companies), correctly determine the type of primer (for concrete or other coating) and comply with all the manufacturer’s requirements for use - then your expectations will be met.

If this stage is carried out in compliance with the technology, then subsequent work (puttying, wallpapering walls, laying tiles, etc.) will also be carried out with high quality and with greater savings in building materials.

All deep penetration primers correspond to good quality, and which one is better cannot be decided unequivocally, because each coating and place of application requires its own type of mixture, which means that all types will be necessary in a particular case.

Content

Almost any type of wall finishing made of concrete and other materials requires preparatory work, for which a deep penetration primer is used. It is necessary to improve adhesion to the finish coating. In addition, the soil can perform an antiseptic, antibacterial or moisture-resistant function. This is very important when processing surfaces. Not everyone knows which primer is better, how to choose it and at what price. You will find this information below.

What is a deep penetration primer

The basis of the repaired surfaces can be different materials– wood, concrete, cement-sand or gypsum plaster. Their properties are different, so their adhesion to the finish will be different. To make it as durable as possible, use a primer. This is impregnation for walls, which can penetrate to a depth of 5-10 mm. It is represented by a wide range on the building materials market. Separately, it is worth noting that it is universal - it is suitable for almost any surface.

Types of primers

Deep-penetrating primer is divided into several other types depending on a number of factors. In composition they can be mineral, acrylic, alkyd, phosphate and quartz. According to the place of application, internal and façade views impregnation. They also differ in purpose - for concrete, wood, metal, ceramic tiles, drywall, brick, etc. The rating of the most popular impregnations of the main types is given below. It reflects the names, technical characteristics, pros and cons and cost of each product in Moscow and St. Petersburg.
