In order for the interior decoration of the house to maintain its ideal appearance for as long as possible, it is necessary to choose a deep penetration primer for processing, which is best suited for this type of surface. Most of the materials that are the basis for applying finishing, in particular concrete and plaster, have a special porous structure, which makes them quite difficult to work with. In addition, many of them are characterized by poor adhesion (adhesion to other materials), which also makes it difficult to carry out finishing works. It is for such cases that a special deep penetration primer was created, which improves the adhesion ability of materials.
At the moment, there are many different types of primer mixtures, the choice of which depends not only on the location of the surface being treated, but also on the type of room in which it is located. Let's try to understand all this diversity.
Choosing a deep penetration primer for the ceiling
In order to select the ideal composition for the ceiling, it is necessary, first of all, to pay attention to the technical characteristics of the surface being treated. Considering the fact that in most cases the floor material is concrete, the primer must have the following technical characteristics:
- small size of dispersion micelles, since the depth of concrete impregnation must be at least 5 mm;
- the primer must have antiseptic properties;
- must have a strengthening effect;
- should significantly improve the surface's ability to adhere;
- close surface pores to ensure less consumption of finishing materials.
The ideal deep penetration primer for interior work, corresponding to all these characteristics are the so-called universal solutions. Penetrating acrylic compounds can also be used.
Which one is better for the floor?
A deep penetration primer for the floor requires slightly different conditions, in contrast to the ceiling, namely:
- closing pores and promoting minimal absorption liquid formulations into the coating;
- increasing the strength of the coating due to strong mechanical loads on the surface;
- high density of the mixture after it dries.
All these requirements are satisfied exclusively by special primers, including those for floors.
Primer for walls
Here the material on which the deep penetration primer will be applied is of great importance, since for this particular surface it can be absolutely anything:
- Wooden walls - the composition for such a surface must have the ability to seal pores, and also be vapor-permeable, so that moisture does not accumulate inside the wall. In this case, it is better to choose a primer containing a large amount of synthetic resins, or choose an acrylic mixture.
- Brick walls - since brick is much denser in structure than wood, such surfaces will require a primer mixture with high penetrating power. In this case, acrylic compounds would be the ideal option.
- Plasterboard walls are characterized by strong water permeability, which is why it is better to prime them with a special quick-drying mixture.
- Plastered walls are characterized by a highly porous surface, which is why the same compositions are used for them as when treating concrete surfaces, for example, acrylic mixtures for concrete.
Choosing a primer for the bathroom
The choice of soil for the bathroom must be approached with particular care, since this room is characterized by high humidity and is a favorable environment for the development of mold, fungi and other microorganisms. Therefore, for priming surfaces in the bathroom, it is better to choose special solutions that have not only high penetration depths, but also antiseptic characteristics, and also contain specialized biocidal additives.
In addition, the rules for applying primer in the bathroom are very important. No matter how good they are technical specifications soil, if the surface is not first degreased, cleaned and dried, all the properties of the composition and your efforts will come to naught. In addition, after you have completed all of the above steps, the surface must be additionally treated with special detergents, which contain chlorides.
Concrete contact or deep penetration primer – what to choose?
One of the popular types of universal primers used recently is concrete contact. Many believe that the highly rated properties of this type of mixture are suitable for any surface and will cope with any problem. Let's try to figure it out.
The technical characteristics of this type of soil are almost ideal for those surfaces that are characterized by high density and low adhesion, since this mixture imitates a surface similar to emery, thereby significantly increasing its adhesion. In all other cases, its use is absolutely pointless and it is better to replace the concrete contact with a special deep penetration primer or a universal acrylic mixture.
Treating the surface with a primer before finishing work is almost a standard procedure, which is intended to significantly facilitate not only the work itself, but also the quality and service life of the finish. The main thing is to choose the right type of composition, depending on the characteristics of the room and the type of surface being treated.
The primer strengthens the surface of the base, improves adhesion to the finishing coating, and also reduces the consumption of building materials. There are mixtures that have antiseptic and moisture-resistant characteristics. The vapor permeability of the material is completely preserved. Primers are used not only for interior decoration floors, walls or ceilings, but also for external work. They can cover any material that can absorb liquid (plasterboard, brick, wood, aerated concrete).
Purpose and composition
Primer mixtures must be used before:
- applying paint,
- wallpapering the walls,
- laying tiles,
- plastering works,
- parquet or linoleum flooring.
A universal look is also suitable for treating a brick wall or concrete ceiling, but still, it is better to choose taking into account the finishing coating so that it really holds up well. The composition of deep-penetrating primers is basically the same, the only difference is in the additional components. Almost all contain water; there are rarely concentrates that require dilution (the proportions depend on the manufacturer). The main component that strengthens the surface of the material is acrylic resin, and various polymer additives deepen the level of penetration. A primer mixture containing a fungicide has antiseptic properties. C latex is used for surfaces with a small number and size of pores to increase adhesion. Mixtures with silicone make the material water-repellent. It is recommended to work with all types at temperatures from 5 to 35 °C.
Operating principle and consumption rate
After application, the deep penetration primer is absorbed into the material. The depth of impregnation is influenced by its characteristics and the condition of the surface being treated, but generally it ranges from 1 to 10 mm. As soon as all the water has evaporated, the resin particles will stick together, thereby forming a single layer. The time for complete drying is influenced by the composition of the water dispersion, environmental conditions and the structure of the surface being treated.
The primer consumption per 1 m2 also depends on the characteristics of the material and its condition. At the same time, this amount varies among different manufacturers, for example, Tiefengrund from Knauf has 70–100 ml/m2, and Grunt from Dufa has 100–200 ml/m2. Russian soils have similar properties, but you can buy them at a lower price (10–25%).
Overview of types of deep penetration primers
All primer mixtures are divided according to composition and area of application:
- acrylic - the most popular, well suited for both brick and drywall,
- alkyd - used purely for coating metal and wood,
- epoxy - protect the metal from oxidation and significantly increase the adhesion of concrete surfaces,
- shellac - prevent the resin from escaping from the wood,
- silicate - suitable for processing brick (silicate, aerated concrete, gas silicate) and plaster (external),
- aluminum - protect wood from high humidity.
To choose the right primer, it is necessary to take into account not only the condition of the surface being treated, but also the composition of the finishing layer, the characteristics of the room and operating conditions. It is very good if the primer mixture and finishing material are produced by the same company.
Deep penetration primers are often used in rooms with high humidity - in the bathroom or kitchen. Due to water, mold appears on the ceiling and in the corners, which ultimately deteriorates the appearance and peels off the coating. For such conditions, VGT VD-AK-0301 with an antiseptic is perfect, at an affordable price (100 rubles per 1 liter). The main thing is to thoroughly clean the surface of dirt before applying the mixture. by special means(containing chlorine). It should be coated with a primer composition at least 2-3 times, and it must include fungicides so that the ceiling does not turn black from mold.
Before choosing and purchasing a primer for the floor, you need to carefully examine its condition, because this part of the room is subject to loads more than others. Therefore, it is best to use a deep penetration mixture, as it provides maximum protection. Such a floor will perfectly withstand both static and dynamic loads, such as the movement of a transport machine. After application, the composition must dry completely and become stronger, only then further repairs can be made.
If the floor is concrete, then a deep penetration primer is better than others, because it makes the surface more durable and significantly reduces the cost of finishing material, especially if it is paint. Tiefengrund from Knauf will cope well with this, as well as many positive feedback has Ceresit CT 17. If the concrete floor has already been painted or for some other reason has poor moisture absorption, then you should choose a composition with high adhesive properties.
If it is coated with deeply penetrating mixtures, it will last for many years, while any finishing materials will fit perfectly and last a long time. A high-quality primer will strengthen the entire sheet and significantly reduce moisture absorption, protect against mold and pathogenic bacteria. Since drywall quickly absorbs water dispersion, it is recommended to choose quick-drying products.
The primer is applied with a roller, brush or spray; the main thing is that all sheets must be perfectly clean so that it is absorbed evenly and as deeply as possible. The entire surface of the drywall, as well as joints and fastening points, are processed. After covering all the seams, it is primed again before wallpapering or painting. If you miss even one area, the paint will peel off or the wallpaper will peel off. Work is carried out only with protective equipment: masks, goggles, gloves.

FOR LOOSE SURFACES
The primer is designed to strengthen weak, loose, crumbling bases, porous, dusty and chalking surfaces, and improve the adhesion of the base to finishing materials.
Application area:
The primer is used to strengthen highly absorbent loose substrates: plasters, bricks, asbestos cement, foam concrete, gypsum, particle boards and plasterboards, concrete. Used to prepare surfaces before gluing ceramic tiles, plastering, puttying, painting, and gluing various types of wallpaper. Can be used as an additive to solutions of sand-cement compositions to impart greater strength and ductility.
- Has high adhesive and penetrating ability
- Impregnates and strengthens crumbling and loose substrates to a depth of 10 cm
- Cures quickly after application
- Significantly improves the adhesion of finishing materials to loose substrates
- Does not isolate water vapor indoors, the surface “breathes”
- Prevents mold growth
- Significantly reduces the consumption of subsequent coatings
- Manufactured in accordance with European standards
- Does not contain organic solvents
- Environmentally friendly, odorless material
- Can be produced in frost-resistant modification down to -45 C
Preparing the base:
The surface should be dried and cleaned of dust and dirt, and other substances that prevent the material from penetrating deep into the base (including fats, oil, wax, bitumen, etc.). Easily peeling layers must be completely removed mechanically.
Application method:
Apply the primer using a brush, roller, or sprayer. Work according to the “wet on wet” principle. The 2nd layer of primer is applied immediately to the wet 1st layer. Do not allow excess soil on the surface to avoid “glazing”. To strengthen weak, crumbling surfaces, dilute with water in a ratio of 1:2 – 1:3, for priming durable dusty surfaces (for example, drywall), dilute in a ratio of 1:4 –1:5. Subsequent work should be carried out only after the surface has completely dried. Stir before use. Work at air and surface temperatures not lower than +5°C. Do not treat frozen surfaces.
*A trial application of the primer to the surface is necessary to determine the optimal degree of dilution, since the absorbency various surfaces depends on their structure.
Instrument care:
Immediately after finishing work, rinse tools with plenty of water. Dried primer can be removed with an organic solvent.
Precautionary measures:
In case of contact with eyes, rinse with water. In case of contact with skin, rinse with water or clean with a damp cloth. Dispose of as household waste. Fire and explosion-proof material.
1 l up to 10 sq.m. single layer coating. The exact consumption depends on the absorbency and structure of the base.
Drying time:
After 1-2 hours at t +25° C and humidity 65%.
Storage conditions:
Keep out of the reach of children. at temperatures above 0°C in a tightly closed container, do not allow freezing. Attention! Store the diluted concentrate for no more than 1 month.
Best before date:
1 year from date of manufacture
Thin-layer acrylic binder, modifying additives, antiseptic, water.
Deep penetration strengthening primer
Monolith – universal acrylic primers deep penetration for loose surfaces
To increase the service life of the coating, before laying tiles, wallpapering, plastering or painting the walls, you need to thoroughly prepare the surface. A high-quality base for performing various works is called a primer. It is also called a primer - a strengthening primer is a type of primer.
When is priming required?
Primer coating of the surface has recently become part of the renovation. For a long time, wallpaper glue, diluted paint, and PVA glue were simply applied as a priming material. On modern market building materials, the choice of primers is huge. Their tasks are very diverse:
- protect surfaces from corrosion,
- give an insulating effect,
- improve the adhesion of paint layers to the base.
Primers are distinguished by type and purpose. The depth of their penetration into the base, the strengthening of this base and the quality of adhesion of the subsequently applied material to the surface depend on this. The use of priming materials reduces paint consumption, which allows significant savings, promotes uniform application of paint and glue, and protects surfaces from fungus and mold.
Features of choice
To choose the right primer, you need to know the type of surface being treated, the characteristics of the given room, and the properties of the material that you plan to subsequently apply. Based on their properties, primer coatings are divided into deep penetration primers and strengthening primers.
Deep penetration soils can saturate the base up to 10 cm deep. This is achieved using components whose components are ten times smaller in size than those of strengthening primers. Strengthening primer mixtures work closer to the surface layers of the base.
The strengthening primer has an effect on the material similar to deep penetration primers, but its composition differs in a large amount of adhesive. It glues loose particles of surfaces that tend to crumble.
Strengthening primer can be distinguished by the appearance of the resulting coating. It leaves a noticeable varnish film.
Acrylic as a base for primer
The best known among strengthening primers is acrylic primer. This is a water-dispersion primer containing small particles of artificial resins. It does not contain solvents or plasticizers. It does not wash off, has no color and dries quickly.
- deep penetration into the treated base,
- the coated surface “breathes”, can allow steam to pass through,
- fireproof,
- glues dust and holds it together,
- has low consumption, allows you to save paint.
Due to the fact that soil materials can be used for interior and exterior work, they are considered universal.
Application of acrylic primer:
- Used for processing seamless floors and finished products. Compatible with plasterboard, cement-fiber, gypsum fiber boards.
- When used on gypsum structures, it imparts moisture to them protective properties.
- It is used for treating substrates coated with lime, lime-cement and lime-gypsum plasters, as a primer before applying paint, wallpapering and laying tiles.
- Used for deep priming of plaster before painting.
The primer coating is traditionally applied with a brush to the walls and floor; for the ceiling, a roller is used. Work is carried out at a temperature not lower than +5°C. After completing the work, all materials used are washed with plenty of water. Mechanical tools must be used to remove dried mixture.
Safety regulations
When performing work, it is necessary to ventilate the premises. In case of contact with eyes, rinse them immediately with water. The storage method is usual: places inaccessible to children. The container is classified as household waste and is disposed of in the standard way.
Storage and movement
Move and store in sealed containers from the manufacturer at temperatures up to +40°C.
If the primer is frost-resistant, then short-term storage, no more than one month, is allowed at temperatures not lower than –30°C. Primers can withstand five freezing cycles. It is necessary to defrost the primer naturally at room temperature. The primer retains its properties for 24 months from the date indicated on the box.
Tips for choosing the right primer
In order to prevent cracks, peeling of paint and putty, and wallpaper from coming off on the coated surface during operation, you need to choose the right primer, which should ensure reliable adhesion of the base and finishing material.
Below are some criteria that influence the choice:
- The presence of one base for the primer and finishing material will subsequently ensure good performance characteristics coverings.
- The extent to which the treated surface is capable of absorbing the primer is taken into account when selecting a primer.
- Strengthening primer is applied to substrates that do not need to be treated. Treating the entire surface with a deep penetration primer will cost more.
- If the ceiling is used in conditions of high humidity, it is necessary to use special universal primer coatings that protect against mold.
The leaders in the production of primer coatings are companies such as Knauf, Ceresit, Primer. The process of applying a primer coating is easy and does not require special skills.
How to choose a strengthening primer?
Strengthening primer is used on surfaces that are prone to crumbling. A high-quality primer mixture will protect the surface well and increase adhesion for better application decorative covering.

*Review of the best sites according to the editors. About the selection criteria. This material is subjective in nature, does not constitute advertising and does not serve as a purchase guide. Before purchasing, consultation with a specialist is required.
Such paint and varnish material as primer finds a wide range of applications. The main task of the soil is to create a special layer between the base and the finish. The resulting substrate must have good adhesion to different materials. Today in the domestic market one can encounter abundance; the consumer is offered expensive and cheap products, in small jars of 0.5-1.0 liters and in huge canisters of 10-20 liters. In order not to make a mistake with your choice, it will be useful to get acquainted with the recommendations of experts.
- Purpose. First of all, before purchasing, you need to know what surface you plan to apply the composition to, and what type of finish will be used in the future. This is very important point, because different materials differ in their ability to absorb. If it is important for metal products to create a good protective layer on the surface, then the primer must penetrate deeply into wood or concrete. After such an operation, the consumption of paint, glue, and plaster will be significantly reduced. The concept of versatility is not always an advantage for a primer, so it is better to give preference to specialized compounds.
- Recipe. Many different primer formulations have been invented, all of them have a common basis. The active substance can be of acrylic, alkyd, polymer or epoxy origin. The solvent most often used is water or an organic compound. But a large number of additives have been created. Antiseptics prevent the appearance of mold and fungi, the introduction of silicones increases the water-repellent properties of the soil, polymer additives increase the depth of penetration.
- Penetration depth. One of the most important parameters of the primer is the degree of penetration into the base. The maximum depth of impregnation is required for porous materials. These are concrete, cement-sand plasters, wood. The depth indicator should be within 10-15 mm. But for metal parts it is more important to create an anti-corrosion layer on the surface with good adhesion. In this case, the penetration depth can be minimal (up to 1 mm).
- Drying time. Since the priming operation is intermediate in the process of repairing premises, buildings or cars, the composition is required to dry as quickly as possible. Most best option 1-2 hours, this time can be used for lunch or preparation for finishing.
- Cost and expense. Cost of primer Russian market varies seriously, even for products of the same brand. The fact is that many well-known companies have created joint production facilities in our country where paint and varnish materials are produced. The quality is not always comparable to the original products, but the low cost is a pleasant surprise. In addition to the price tag, it is important to find out the primer consumption for each type of base. Often cheaper primers require 2-3 layers of application, which leads to increased consumption. This point should be taken into account when comparing several products.
We have selected the 15 best primers for our review. All of them are sold in Russia. When distributing places in the rating, the opinion of the expert community and consumer reviews were taken into account.

Priming the walls is necessary so that the subsequently applied decorative coating could last as long as possible. That is, the primer provides the strongest possible adhesion between the main surface and finishing, increases the service life and quality of the coating. The emulsion, penetrating into unnoticeable recesses and filling them, saturates the entire surface to be treated.
The bulk of emulsions presented on the building materials market are a colloidal aqueous solution consisting of a polymer dispersion and various additives. After application to the surface, the priming emulsion fills the pores and microcracks, dries, and the polymer particles, bonding with each other, form a continuous, homogeneous film that allows steam and air to pass through, while remaining waterproof.
Benefits of priming
The primer composition does not absorb moisture from the freshly applied coating, giving it the opportunity to dry without the formation of cracks and peeling. This is especially important in cases where the decorative coating will be applied to highly absorbent surfaces, for example, aerated concrete, sand-lime brick and so on.
Plaster, putty and tile adhesive adhere better to a primed surface because the base becomes more sticky. In addition, some types of primers contain antifungal and antimicrobial additives that prevent the formation of mold.
Types and applications
There are several types of primer compositions:
- anti-corrosion facade primer - used to prevent rust on metal. A special composition is used to process zinc;
- to prevent the formation and development of mold and fungi, it is recommended to use a deep penetration antifungal primer;
- An impregnating composition is used to strengthen the surface. It is intended for processing fragile coatings and drywall, as well as before laying ceramic tiles;
- To protect the treated surface from moisture, a special primer or paint is used, which is applied immediately before finishing. These hydrophobic compounds can be purchased at building materials stores. It is worth noting that the primer compositions under consideration are used for both interior and exterior work. The choice of emulsion directly depends on the quality and material of the surface being treated. In this case, various facade primers are used, including acrylic and alkyd types;
- To finish wooden surfaces from the outside, a special antiseptic deep penetration primer is used, which allows you to seal existing joints and cuts. When painting wood, experts recommend using an alkyd-oil composition of façade primer. This is because the oil is quite elastic and has excellent penetrating ability.
Components
Deep penetration primer for facades is a mixture of water and polymer resins. Facade primer emulsion has deep penetration into porous and loose materials, easily filling all voids. After the water evaporates, the composition begins to polymerize.
The primer composition should be selected taking into account the type of surface to which it will be applied. Before priming, as well as before painting, it is necessary to first clean the surface to be treated from dirt and dust, and then dry it.
Metal parts of the facade should be cleaned of rust. The primer or paint is applied with a brush, roller or spray gun. The main thing is that the applied layer is completely dry.
For priming concrete surfaces, experts recommend using a special composition - concrete contact. This primer composition is used for treating dense bases that do not absorb moisture, before direct plastering or puttying.
Concrete contact contains fine concrete, which results in high adhesion of finishing materials to smooth surfaces. Concrete contact is used for external and internal work at a temperature not lower than +5˚C. If, for example, you need to install ceiling tiles, on a whitewashed surface, then such treatment will significantly increase the chances that the material will adhere firmly.
Universal primer compositions are suitable for treating highly absorbent surfaces. Such surfaces include plasterboard, brick, cement strainer, aerated concrete, plaster and the like. A universal, deep-penetrating primer increases adhesion, reduces paint consumption, strengthens weak surfaces and prevents wallpaper from coming off the walls.
After the installation of plasterboard sheets has been completed, the surface must be primed before puttying, especially in the cutting areas. The consumption of priming emulsion is insignificant, but the benefits are undoubted, since the surface of the drywall becomes more durable and adhesive.
For priming, you should choose a tool based on the type of surface. If you need to treat large areas (ceiling, walls or floor), then you can use a paint brush with medium pile, and in hard to reach places or corners, as a rule, use a brush up to 100 mm.

With a penetration depth of 1-5 mm, the emulsion consumption is 100-200 ml/m², depending on the absorbency of the surface.
Bolars deep penetration soil
The primer is made on the basis of acrylic, which allows you to obtain high strength and durability of the coating, as well as reduce paint consumption. Bolars primer regulates water absorption, increases adhesion and abrasion resistance, and allows walls to breathe. Apply to brick, concrete and aerated concrete surfaces, as well as drywall. Can be used for both external and internal work. Primer consumption is 80 ml/m².
Application and consumption of primer composition
Facade priming emulsion or paint is applied only after leveling the working surface, for which coarse sandpaper is used. The primer should be applied evenly, and be sure to ensure that it does not get into your eyes. After work, you should wash and clean the tool thoroughly. The remaining primer, only if it is not a concentrate, can be poured back into the container.
To obtain greater effect, the primer composition is applied in two or more layers. Drying on average lasts 1-4 hours, while the ambient temperature should not be lower than +20˚C.
The consumption of some types of soil is:
- deep penetration emulsions - 100 ml/m²;
- concrete contact - 350 ml/m²;
- decorative primer - 200 ml/m²;
- special compositions for walls - 50-100 ml/m².
In principle, primer consumption depends on the surface material, its characteristics and the manufacturer of the mixture. In addition, all the main characteristics, consumption, drying time, and so on must be indicated on the container of soil compositions.

Before answering the question of which deep penetration primer is better, you should understand its purpose and classification. This is due to the fact that different types of primer mixtures have specific characteristics that are most pronounced under certain operating conditions. Therefore, we will consider why priming of walls, ceilings and other finishing surfaces is needed and what types of it exist.
Purpose of primer mixtures
Even the highest quality finishing material can crack, peel or fall off over time. To avoid such troubles, before finishing any surface it is necessary to carry out a series of preparatory activities, among which priming plays an important role.
Deep penetration primer allows you to:
- increase base adhesion;
- hide small unevenness in the base and make it stronger;
- increase resistance to humid environments, harmful microorganisms and low temperatures;
- reduce the consumption of finishing material.
Deep penetration primers have many properties, among which the most significant are:
- Penetration depth. Depends on the porosity of the surface being treated and is up to 8-10 mm.
- Drying time. At a temperature of 20-23 °C and a humidity of 55-65%, the drying time for most mixtures is on average about 24 hours.
- Application temperature. The primer can be applied at ambient temperatures from +5 to +30 °C.
- Maximum particle size. Is no more than 30 nm.
- Antiseptic properties. Some brands contain antiseptic substances that protect the finishing surface from fungus and mold.
Main types of primers
When choosing a particular primer mixture, the following factors must be taken into account:
- what the base is made of (wood, brick, concrete, etc.);
- what will be used as finishing (plaster, paint, tile);
- Do you need a primer for facades or for preparatory work indoors.
All types of deep penetration primers differ:
- by composition;
- purpose;
- characteristics;
- place of application;
- to the manufacturer.
Tikkurila is a well-known brand that produces high-quality primer Based on their composition and purpose, primers are divided into mineral, quartz, alkyd, acrylic and phosphate. If the base is made of metal or wood, and you plan to use paint as a finishing material, then the best option in this case would be an alkyd mixture. To treat brick and concrete walls with your own hands, it is recommended to use mineral and acrylic liquids, and with protection metal elements Glypthal solutions can successfully combat corrosion.
The main task of a deep penetration primer is to increase the adhesion of the base and strengthen it. However, many mixtures additionally make it possible to protect the finishing surface from negative environmental factors (primers for facades) and harmful microorganisms (antiseptic solutions), to increase its resistance to elevated temperatures, corrosion, etc.
Ceresit is a guarantor of quality According to the place of application, all primers are divided into façade and for internal use. Primers for facades have increased viscosity and better resistance to negative environmental factors. Such mixtures are also recommended for processing and internal surfaces in rooms with high humidity levels.
When considering manufacturers of deep penetration primers, it should be noted that today on the market you can find mixtures of both foreign and domestic brands.
Such solutions include Tikkurila, Ceresit, Perel, Mixonit, Moment and Eurolux.
The best option for priming walls before laying artificial stone and tiles are primed with Mixonit primer, the penetration depth of which is 10 mm. This mixture has vapor permeability and antiseptic properties, which is especially important for wall cladding in the bathroom and kitchen.
One of the highest quality primers is Ceresit. They can treat any external and internal surfaces. It has a high degree of penetration, reduces the absorption of the base, improves the spreadability of leveling solutions and protects plaster mixtures from drying out and cracking. The only drawback of Ceresit is its high cost, so if you have a limited budget, you can purchase Moment or Eurolux primer.
Do-it-yourself façade priming of walls
Priming is a fairly simple process that anyone can do on their own. Facade primer for walls is applied to a previously prepared base. To do this, the old finishing material is removed from it, after which the surface is thoroughly cleaned of construction debris and dust.
After this, using a roller or wide brush, the primer is evenly applied to the wall. All work is carried out at positive temperatures, since at negative temperatures the useful qualities of the mixture are reduced. In most cases, the primer is applied twice: before puttying and after sanding (immediately before finishing). Wherein further work can only be carried out after the primer liquid has completely dried.
