Covering the working surface with soil during repair work is a mandatory step. However, the question often arises which primer is better for processing a particular coating. An important factor when choosing is the quality and price of the component.
The choice is also made difficult by the large number of various offers on the market, because they all have their advantages and disadvantages.
Everyone has heard about priming the surface before finishing (painting, laying parquet or other flooring material), but not everyone knows why it is needed. By the way, the main function of the primer is indicated by the constituent components.
Roller primer application
Depending on the type of working coating and performance, the required deep penetration primer (antiseptic, universal or with improved adhesive properties) is selected.
Priming compounds:
- increase the adhesive properties of the working surface;
- guarantee an even application of the top layer and reduce the consumption of finishing materials;
- increase the water resistance of the working surface;
- increase resistance to mechanical stress and surface density;
- most of the formulations have antiseptic properties, which reduces the number of microorganisms on the surface.
Nowadays, universal primers are popular on the market, but you should not use them on all surfaces. Specialists use this type of primer only for small amounts of work, applying to floors, walls and ceilings.
Primer promotes adhesion of the surface to the finish and prevents mildew For large volumes of work, choose a primer mixture carefully, based on the characteristics of the working surface and its condition.
Types of primers
- Acrylic
This mixture, along with acrylic paint, is applied to almost all surfaces (concrete, wood, brick, chipboard, plaster), and is suitable for floors, walls, and ceilings. The water-based acrylic mixture almost does not smell, dries up in 2-4 hours, if necessary, the composition is mixed with water. However, the water-based primer is not used as a protective coating on ferrous metals - it is corrosive.
Acrylic blend - Alkyd
This type of primer is applied to metal and wood materials. In addition, it is considered better than other mixtures in terms of priming untreated wood flooring or walls. After application, the "bristling" surface of the wood becomes smooth and convenient for applying the next top coat of finishing. Alkyd primer mix can be used in one coat without additional finishing.
A noticeable disadvantage of this mixture is that it does not cover plaster and gypsum materials, because the alkyd component gives the surface a roughness.
- Shellac for wood
This type of primer is used to hide knots, chips, cracks and resins on wood, applied to floors, walls and ceilings. Much less often, this mixture plays the role of an insulator for aqueous solutions of stains. The composition is dominated by the milky sap of insects and the usual methyl.
- Primer mix for metal
The main task of this primer is anti-corrosion treatment of metal materials. But here, too, everything is not simple, for different metals requires their own subtype of primer mixture. For aluminum, the phosphating type is used, for steel and ferrous metal, alkyd and alkyd-urethane solutions are used.
Application of a primer with a spray gun - Primer mix for concrete
This type of primer is used in painting schemes for topcoat. The mixture is selected based on the characteristics of the working coating, since these primers have a different composition, suitable for different concrete applications. A polyurethane and epoxy primer mixture is suitable for covering floors and walls.

Scope of application of the deep penetration primer mixture
A deep penetration primer was invented for the preparation of porous, rough surfaces, because they need an adhesive effect and increased resistance to destructive influences, including moisture.
A deep penetration primer is used for both indoor and outdoor work. Internal work involves puttingtying, painting, laying drywall. External include applying the mixture to concrete, foam concrete, aerated concrete. The primer is the only solution in preparing the surface for further finishing.
Similar mixtures are used in conditions of high humidity.
A deep penetration primer helps to eliminate a long-standing problem with kitchens and baths in the area of \u200b\u200bfloors, walls and ceilings, minimizes the chance of mold and various fungi due to the presence of an antiseptic component in the composition.
One of the best options for interior work is Knauf Primer Mix, it is multifunctional, making it the market leader. Knauf primer is suitable for floors, walls and ceilings.
Distribution of the primer on the floor How to choose the right Knauf primer?
It often turns out that choosing a primer for wallpaper is easier than deciding on a composition for the floor. After all, it is necessary to consider when choosing many factors related to the characteristics of the application.
If the floor surface is concrete, carefully examine its condition. If compaction of concrete porosity or removal of roughness is required, then a deep penetration primer is required. For roughness, Knauf mixtures with oozing properties are used; these compositions give good results on old repaired surfaces.
Use a mixture with increased adhesive properties and low moisture absorption in concrete. This occurs if the surface has been painted.
The photo above shows the application of Knauf primer to the floor. It adheres evenly to the working surface and impregnates the concrete underneath, seals and increases resistance to external influences. Knauf primer has a high adhesive property and increased moisture resistance.
Surely it is very difficult to determine the composition that suits better than others. Take into account the characteristics of the floor or ceiling surface, the operating conditions, and, if necessary, other external factors.
When choosing a primer for aerated concrete and aerated concrete, similar rules apply. Do not forget that the connection of the components in its composition plays an important role. As a result, the choice of primer mix is \u200b\u200bdirectly dependent on the final coat.

* Review of the best according to the editorial site. About selection criteria. This material is subjective and does not constitute advertising and does not serve as a purchase guide. Before buying, you need to consult with a specialist.
Such a paint and varnish material as a primer finds a wide scope of application. The main task of the primer is to create a special layer between the base and the finish. The formed substrate should 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 0.5-1.0 liter cans and in huge 10-20 liter cans. In order not to be mistaken with the choice, it will be useful to get acquainted with the recommendations of experts.
- Appointment... First of all, before buying, you need to know on which surface you plan to apply the composition, and what type of finish will be used in the future. This is a very important point, since 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 significantly decrease. The concept of versatility is not always an advantage for a primer, so it is better to give preference to specialized formulations.
- Recipe. Many different primer formulations have been invented, they all have a common basis. The active ingredient can be of acrylic, alkyd, polymer or epoxy origin. The most commonly used solvent 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-repellency of the soil, polymer additives increase the penetration depth.
- Penetration depth... One of the most important parameters of the primer is the degree of its penetration into the base. The maximum impregnation depth 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 with good adhesion on the surface. 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. The most optimal option is 1-2 hours, this time can be used for lunch or preparation for finishing.
- Cost and consumption... The cost of a primer on the Russian market fluctuates seriously, even for products of the same brand. The fact is that many well-known companies have established joint ventures in our country, where paints and varnishes 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 consumption of the primer for each type of base. Often, cheaper primers require 2-3 coats, which leads to increased consumption. This point is worth considering when comparing multiple products.
We have selected 15 of the 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.

The use of primer mixtures during repairs is quite justified, because any finishing material must be very strong and reliable on the base. For this, a primer is used, and this article will help you which one to choose for walls and a stream.
Types of modern primer
Modern manufacturers offer a huge number of primers. It is not always easy to choose the necessary types of primers for concrete, plaster, putty. For this purpose, one must first of all know the varieties.
Depending on the area of \u200b\u200bapplication, the types of primers for walls and ceilings are divided into the following groups:
- Alkyd: used only for wooden surfaces and metal structures;
- Acrylic: have universal properties, respectively, suitable for different surfaces. Compounds from this group penetrate 1 cm deep. This property allows the use of acrylic primers for deep impregnation of the base;
- Aluminum: only used for wood. With their help, the wood is completely isolated from moisture, thereby minimizing the occurrence of such unpleasant phenomena as mold or mildew;
- Polyvinyl acetate: used only when using paint of a special composition for priming concrete, wood, metal, plaster;
- Shellac: helps to prevent the release of resin by wood, respectively, used as a type of primer for ceilings and walls;
- Epoxy: Suitable for deep impregnation of metal and concrete surfaces. Their main advantage is protection against corrosion and sufficient strong adhesion.
Based on the classification presented above, before, it is necessary to determine the material of the surface to be primed and only then to acquire the mixture.
When choosing a primer, pay attention to the manufacturer, price and specifications. The deeper the level of soil penetration into the base, the better it is for any purpose.
All about acrylic compounds
The most common primer you can choose in different cases is acrylic. It is versatile and makes the final finish high quality and durable. In turn, the types of acrylic primers also have their own classification and, depending on the conditions of use and the purpose of the primer, are divided into:
1. Universal: used on all surfaces and in all conditions. This primer is equally well suited for both indoor and outdoor finishing work. If you do not know how to choose a primer for wallpaper, what to use for subsequent tiling or just painting, take a universal one. The solution of this mixture is slightly turbid, almost colorless. A special place in a wide range of universal acrylic primers is occupied by a very popular primer paint today. Its use helps to solve several problems at the same time: to reliably bond the surfaces, get rid of the possible appearance of mold and fungal bacteria, apply a layer of paint. The composition is white and the surface is not only primed, but also painted.
Tip: you can buy primer paint at any store. You can achieve the desired color by adding dye to the primer. For example, after priming, the wall will be painted blue. Add blue dye and the first coat is ready.
2. Deep penetration formulations have all the characteristic qualities of acrylic primers. However, this type of primer penetrates much deeper into the surface to be treated, smoothes it, thereby adhering the base more strongly.
The absorption length reaches 1 cm. In the question of which deep penetration primer to choose or the usual universal one, the first group should be given priority. The smoothing effect makes the surface perfectly flat, as fine particles, sand and dust stick together. This is a great option for priming walls for wallpaper, plaster and even tiles.
3. Adhesive: there is a quartz impurity in the composition, which makes the surface a little rough, which, in turn, glues heavy finishing materials much stronger. This is a good way out when you don't know how to prime the walls in front of the plaster.
Application methods: when and how to do it
The method of applying the primer is not fundamentally different from the methods of applying other finishing materials. The surface is cleaned, smoothed, sanded and degreased if necessary. The question of how many times the walls or ceiling need to be primed requires an individual approach, but at least twice.
For application, such tools are used as:
- Roller.
- Brush.
- Pulverizer.
Roller application In each case, the tool is selected individually. For example, it is better to apply a primer on a brick surface with a brush, but on a flat ceiling or drywall - with a roller. The pulverizer is used less often, since it is not easy to clean the entire room afterwards.
Ceiling preparation
Starting to repair the ceiling on your own, you need to study the information on how to properly prime the ceiling. Indeed, despite the seeming simplicity of work, there are certain rules:
- Having determined how to prime the ceiling, try to do it evenly. Incorrect distribution, after painting it will be immediately visible. The place where the primer is applied thicker will be darker than the entire surface.
- Before priming the ceiling before painting, select the direction of application of the bonding material. With one layer of primer, this is done along the room, perpendicular to the wall with the window. In a two-layer application, the first layer runs parallel to the wall with the window, the second - perpendicular to it.
Preparing the walls
It is necessary to prime the walls in any case. Another question is the best way to prime the walls, but more on that later. Before priming, the surface requires mandatory preparation: it is necessary to remove the old coating, smooth out irregularities, putty the cracks, remove dust and dirt.
In work, you should adhere to technology, and not whip everything up. The first coat of primer must be dry and only then can a second coat be applied. It is necessary to distribute evenly. Particular attention should be focused on the moment when you need to prime the walls under heavy wallpaper. In such cases, wallpaper glue cannot be used as a primer (as many advise).
Of course, one can argue, why do you need to prime the walls if they will be glued anyway? First of all, the wallpaper will hold on tightly, it will not bubble when gluing. And in the future, no filth in the form of mold or mildew will appear on such walls.
How and with what the walls are primed for painting
The priming of the walls is mandatory, and when asked what to prime the walls before painting, we can safely say - a universal primer. It has all the necessary properties and is suitable for different situations.
Very often you have to decide whether you need to prime before painting? Some people think no: the primer mixture, drying out, leaves stripes that stand out clearly after painting. And dust and dirt can be removed with a vacuum cleaner. Others, on the contrary, argue that this must be done. Here you will have to decide on your own. If you want a practical repair - prime, if you want to save money - do not prime.
Often the walls are made of plasterboard, as it is an affordable and practical material. Usually it is perfectly flat and, accordingly, many are interested in whether it is necessary to prime drywall? Yes, sure, because the priming process not only evens out the walls, but also serves as an excellent factor in adhesion of the base to the finish.
In this case, they use a universal primer, performing the work in the following sequence:
- Primed for the first time;
- Putty;
- Re-primed.
Only after complete drying, they start painting the surface.
Advice: when working with a primer, the room temperature should be within 5-20 degrees Celsius, air humidity up to 75% and no drafts.
How and with what the walls are primed for plaster
wall priming Plaster is used on brick, concrete or aerated concrete surfaces. They, as a rule, have high friability and absorbency, and the question of whether it is necessary to prime before plastering is beyond doubt. Select a deep penetration primer in these cases. It not only adheres perfectly, but also has antiseptic properties.
It is necessary to prime in several layers before plastering. Better to use a brush or roller. Each layer dries for about an hour and at this time it is necessary to protect the walls from dust and dirt. The temperature indicators of this type of primer are the same as the universal one. The main thing is to carefully read the instructions and follow them.
Exactly the same requirements are imposed when the question arises whether it is necessary to prime before putty. Everything is the same, even more, because not a single finishing material will hold on to a clean layer of putty.
The primer strengthens the surface of the base, improves adhesion to the topcoat, and also reduces the consumption of building materials. There are mixtures with antiseptic and moisture resistant characteristics. At the same time, the vapor permeability of the material is fully preserved. Primers are used not only for interior decoration of the floor, walls or ceiling, but also for external work. They can be coated with any material capable of absorbing liquid (drywall, brick, wood, aerated concrete).
Purpose and composition
Primer mixtures must be used before:
- applying paint,
- pasting walls with wallpaper,
- laying tiles,
- plastering works,
- flooring of parquet or linoleum.
For processing a brick wall or concrete ceiling, a universal look is also suitable, but still, it is better to choose taking into account the topcoat so that it really sticks well. The composition of deeply penetrating primers is basically the same, the only difference is in additional components. Almost all contain water; concentrates that need to be diluted are rare (proportions depend on the manufacturer). The main component that strengthens the surface of the material is acrylic resin, and various polymer additives make the penetration level deeper. The priming mixture containing the fungicide has antiseptic properties. With latex it is used for surfaces with a small number and size of pores in order 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.
Principle of operation and consumption rate
After application, the deep penetration primer is absorbed into the material. The impregnation depth is influenced by its characteristics and the condition of the treated surface, but generally it ranges from 1 to 10 mm. As soon as all the water has evaporated, the resin particles stick together, thereby forming a single layer. The time of complete drying is influenced by the composition of the aqueous dispersion, the ambient conditions and the structure of the surface to be treated.
The consumption of the primer per 1 m2 also depends on the characteristics of the material and its condition. At the same time, this amount differs for different manufacturers, for example, for Tiefengrund from Knauf - 70-100 ml / m2, and for Grunt from Dufa - 100-200 ml / m2. Russian soils have similar properties, but you can buy them at a lower price (by 10-25%).
Overview of types of deep penetration primers
All primer mixtures are divided according to composition and field of application:
- acrylic - the most popular, well suited for both brick and drywall,
- alkyd - used especially for coating metal and wood,
- epoxy - protect the metal from oxidation and significantly increase the adhesion of concrete surfaces,
- shellac - do not allow the resin to stand out from the tree,
- silicate - suitable for processing bricks (silicate, aerated concrete, gas silicate) and plaster (external),
- aluminum - protect wood from high humidity.
To choose the right primer, it is imperative to take into account not only the condition of the surface to be treated, but also the composition of the finishing layer, the characteristics of the room and the operating conditions. It is very good if the primer mix and the finishing material are from the same company.
Deep penetration primers are often used in rooms with high humidity - in the bathroom or in the kitchen. Due to water, mold appears on the ceiling and in the corners, as a result, the appearance deteriorates and the coating peels off. 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 from contamination with special agents (containing chlorine) before applying the mixture. It should be coated with a primer at least 2-3 times, while 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 more exposed to stress than others. Therefore, it is best to use a deep penetration mixture, as it is this that provides the maximum protection. Such a floor will perfectly withstand both static and dynamic loads, such as, for example, the movement of a transport machine. After application, the composition must completely dry out and get stronger, only then further repairs are 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 do it well, Ceresit CT 17 also has a lot of positive reviews. If the concrete floor has already been painted or for some other reason has poor moisture absorption, then a composition with high adhesive properties should be chosen.
If it is covered with deeply penetrating mixtures, then it will serve for many years, while any finishing materials will perfectly fit and hold for 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 aqueous 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 is processed, as well as joints and attachment points. After covering all the seams, it is primed again, before wallpapering or painting. If you skip at least one section, then the paint will peel off or the wallpaper will peel off. Work is carried out only with protective equipment: masks, glasses, gloves.

FOR LOOSE SURFACES
The primer is designed to strengthen weak, loose, crumbling substrates, porous, dusty and chalky surfaces, and to improve the adhesion of the substrate to finishing materials.
Application area:
The primer is used to strengthen highly absorbent loose substrates: plaster, brick, asbestos cement, foam concrete, gypsum, chipboard and gypsum plasterboard, concrete. It is used to prepare surfaces before gluing ceramic tiles, plastering, puttying, painting, gluing various types of wallpaper. It can be used as an additive in solutions of sand-cement compositions to impart greater strength and plasticity.
- Possesses high adhesive and penetrating power
- Impregnates and strengthens crumbling and loose substrates up 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 the requirements of European standards
- Does not contain organic solvents
- Environmentally friendly odorless material
- Can be produced in frost-resistant modification up to -45 С
Base preparation:
The surface should be dried and cleaned of dust and dirt, and other substances that prevent the penetration of the material deep into the base (including grease, oil, wax, bitumen, etc.). Lightly peeling layers must be completely removed mechanically.
Application method:
Apply the primer with a brush, roller, spray. Work according to the “wet on wet” principle. The 2nd coat of primer is applied immediately to the wet 1st coat. Avoid excess soil on the surface to avoid "dripping". To strengthen weak crumbling surfaces, dilute with water in a ratio of 1: 2 - 1: 3, for priming durable dusty surfaces (eg drywall) dilute in a ratio of 1: 4 - 1: 5. Subsequent work should be carried out only after the surface is completely dry. Stir before use. Work at an air and surface temperature of at least + 5 ° C. Do not handle frozen surfaces.
* A trial application of the primer to the surface is necessary to determine the optimum dilution rate, as the absorbency of different surfaces depends on their texture.
Instrument care:
Rinse the tools with plenty of water immediately after finishing work. Cured primer can be removed with an organic solvent.
Precautions:
In case of contact with eyes, rinse with water. In case of contact with skin, wash off with water or clean with a damp cloth. Dispose of as household waste. Fire and explosion proof material.
1 l to 10 sq.m. single layer coating. The exact consumption depends on the absorbency and structure of the substrate.
Drying time:
After 1-2 hours at t + 25 ° C and 65% humidity.
Storage conditions:
Keep out of the reach of children. at temperatures above 0 ° C in a tightly closed container, do not freeze. Attention! Store the diluted concentrate for no more than 1 month.
Shelf life:
1 year from the date of manufacture

PRIMER deep penetration strengthening
Monolith - universal deep penetration acrylic primer for loose surfaces
To increase the service life of the coating, before laying tiles, wallpapering, plastering or painting walls, you need to thoroughly prepare the surface. A high-quality basis for performing a variety of works is called a primer. It is also called a primer - a strengthening primer is a type of primer.
When priming is required
Surface priming has recently become part of the renovation. For a long time, wallpaper glue, diluted paint, PVA glue were simply applied as a primer. In the modern building materials market, 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 primers reduces paint consumption, which allows significant savings, promotes uniform application of paint, glue, protects surfaces from fungus and mold.
Selection features
To choose the right primer, you need to know the type of surface to be treated, the features of the room, the properties of the material that is planned to be applied later. According to their properties, primer coatings are divided into deep penetration primers and strengthening primers.
Deep penetration soils can penetrate the base up to 10 cm deep. This is achieved with the help of components, the components of which are ten times smaller than those of strengthening primers. Reinforcing primers work closer to the surface layers of the substrate.
The reinforcing primer has an effect on the material similar to that of deep penetration primers, but differs in composition by a large amount of adhesive. It sticks together loose particles of surfaces that tend to crumble.
The reinforcing primer can be distinguished by the appearance of the resulting coating. It leaves a noticeable lacquer film.
Acrylic as a base for primer
The best known among the strengthening primers is the acrylic primer. It is a water-dispersion primer containing small particles of artificial resins. It does not contain solvents or plasticizers. It is not washed off, colorless and dries quickly.
- deep penetration into the treated substrate,
- the coated surface "breathes", can pass steam,
- fireproof,
- glues the dust and holds it together,
- has a low consumption, saves paint.
Due to the fact that soil materials can be used for indoor and outdoor work, they are universal.
Application of acrylic primer:
- Used for screed and finished products. Compatible with gypsum plasterboards, fiber cement boards, gypsum fiber boards.
- When used on gypsum structures, it gives them moisture-proof properties.
- It is used for treatment of substrates covered with lime, lime-cement and lime-gypsum plasters, as a primer-impregnation before applying paint, for wallpapering and laying tiles.
- Used for deep priming of plaster before painting.
A primer is traditionally applied with a brush to the walls and floor, a roller is used for the ceiling. Works are performed at a temperature not lower than + 5 ° C. After completing the work, all materials used are washed with plenty of water. Power tools must be used to remove dried mixture.
Safety rules
When performing work, it is necessary to ventilate the premises. In case of contact with eyes, rinse immediately with water. Storage method is usual: places inaccessible to children. The container is classified as household waste and is disposed of in a standard way.
Storage and movement
Move and store in a sealed manufacturer's container at temperatures up to + 40 ° C.
If the primer is frost-resistant, then short-term storage is allowed, no more than one month at temperatures not lower than –30 ° С. Primers withstand five freeze cycles. 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 paint and putty, or the wallpaper from coming off 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 of the criteria that influence the choice:
- The presence of one base for the primer and the finishing material will subsequently provide good performance characteristics of the coating.
- How much the surface to be treated is able to absorb the primer is taken into account when choosing a primer.
- The hardening primer is applied to substrates that do not need to be treated. Treating the entire surface with a deep penetrating primer will cost more.
- If the ceiling is operated in high humidity conditions, it is necessary to use special universal ground coatings that protect against mold.
The leaders in the production of primer coatings are such companies as Knauf, Ceresit, Primer. The priming process is easy and requires no special skills.
How to choose a reinforcing primer?
A hardening primer is used on surfaces that are prone to crumbling. A good quality primer mix will protect the surface well and increase adhesion for a better decorative finish.
It is difficult to name at least one type of finishing work where a deep penetration primer is not required, well, except that the compositions from the "2 in 1" or "3 in 1" series, which already include a primer component. The priming process solves several problems at once - it improves adhesion, strengthens the base, holds the finish lining, regulates the degree of the absorbent component and increases the service life.

Specifications
Any deep penetration primer includes 3 main components - water, acrylic resins and polymer components. Their proportion can be different, but the basic composition is the same, where resins are responsible for viscosity and adhesion, and polymers provide really deep penetration.
Depending on the variety, the multicomponent composition may contain:
- antiseptics (antifungal primer for deep penetration on concrete) - exclude the appearance of mold and the development of fungal strains;
- silicones (water repellent) - for outdoor use to increase resistance to precipitation;
- latex or acrylic - to increase adhesion and extend the life of the finish coat.
Important! If the composition contains various components, the composition is called "universal" and can be used with equal success for finishing different bases - wood, metal, concrete, brick, etc. Most often, Lacra and Volma practice universal formulations.
The compositions are used on almost all surfaces, but this is especially necessary on highly absorbent, porous, crumbling and unstable bases. Metal, for example, must be primed so that the paint lays down evenly, does not roll and crack in the future. Wood and concrete are very porous substrates, in which case the soil literally sticks together into a monolithic surface (film), and the varnish-and-paint coating lays down neatly on top, without penetrating deep capillaries.
The characteristics and requirements for the composition are regulated by GOST R 52020-2003 "Water-dispersive paint and varnish materials", a certificate of conformity is required.
Each composition shows its own characteristics that must be taken into account when processing the base, including how much one or another option dries. Below is a ranking of the best deep penetration primers from different manufacturers. It was compiled according to customer reviews and estimates of professional builders, and the cost was also taken into account.
Concrete is the most popular building material, known for its density and strength. Along with these characteristics, it is known for its porosity, which complicates its finishing, increases material consumption and promotes paint peeling. Deep penetrating agents for concrete are water-soluble compounds based on polymers and latex, which deeply penetrate and bond together in a monolithic film. These qualities contribute to deep diffusion and hardening of concrete.
Ceresit CT 17
Water-dispersible composition for strengthening the surface, binding dust particles and reducing the absorbency of concrete. Penetrates up to 10 mm. Convenient tinting - the composition is light yellow, so you can easily distinguish the treated surface from the untreated one.

Types of plastering works requiring obligatory priming:
- putty;
- laying tiles of different formats and materials;
- staining;
- wallpaper sticker;
- application of decorative plaster, including "liquid wallpaper";
- laying of parquet, carpet, linoleum.
Before applying, the base must be prepared - they remove debris, dust, cleaned of paint and oil stains.
Almost all types of exterior finishes require preliminary preparation of the substrate to improve adhesion to the topcoat, to perform antiseptic, antibacterial and water-repellent tasks. This is very important when processing surfaces exposed to rainfall, sunlight and wind.
TEX 2 in 1
It is intended for the preparation of concrete, plastered, plasterboard, brick and wooden surfaces before the subsequent painting with water-dispersion paints, filling, facing with tiles, porcelain stoneware, siding and other finishing materials. Penetrates into layers up to 6 mm, strengthens the base, improves adhesion of the coating to the surface, evens out the absorbency of the substrate.
Specifications:
The versatility of the composition is explained by the inclusion of antibacterial and antiseptic components. Does not work on metal - it will not protect against corrosion. It is applied in any convenient way - roller, brush, spray. Reduces paint consumption by one third.
The primer reduces the absorption of moisture, which enhances the adhesion of the substrate and prevents cracking of the screed or leveling coating. It is recommended to use in conjunction with cement-based adhesive mixtures, self-leveling compounds. It is used for the treatment of surfaces such as: screeds and plasters from cement-sand and plaster compositions. Ideal for outdoor concrete work.
Specifications:
Can be used on previously painted surfaces with acrylic paint. Not suitable if alkyd and oil enamels have been previously used.
It is used to strengthen and prepare weak, porous substrates for further facade finishing. Thanks to the active ingredients, the primer composition penetrates into the pores of the base, impregnates and adheres. After application, the working surface gains strength, low water consumption, uniformly high adhesion to plasters, leveling compounds and tile adhesives over the entire area.
Specifications:
It is applied using standard methods. Although it does not contain solvents, it is of little use for internal work. The main purpose is the processing and preparation of the facade.
The basis of the foundations of any finishing work, especially when it comes to such a porous material as aerated concrete. Its water absorption coefficient is simply enormous - it reaches 35% of its own weight. Only in the case of preliminary application of the primer, the coating will not crack, crumble, the paint will not roll, but most importantly, moisture of the walls and all associated negative consequences are excluded.
Eskaro Aquastop Facade
The concentrated mixture with the addition of siloxane is a one-component waterproofing mastic designed for exterior and interior finishing of foam and aerated concrete, gas silicate blocks. The fundamental difference from other primers is the improvement of the hydrophobic properties of the surface and the provision of high vapor permeability. Otherwise, it works the same way - it evens the absorbency and reduces the consumption of finishing materials.
Eskaro Aquastop Facade
Specifications:
Presented as a concentrate. Diluted with water in the following proportions:
- 1: 5 - under the wallpaper;
- 1: 3 - before painting highly absorbent, porous surfaces;
- 1: 4 - before painting surfaces with normal porosity.
Cannot be used undiluted - a high percentage of dry residue forms a slippery film on which no coating, especially paint, will "stick".
Prepares aerated concrete surface for high quality finishing. Does not penetrate deeply - maximum 4-5 mm, its purpose is slightly different - to increase the adhesive properties of the porous surface. After drying, a rough layer is formed, which has high adhesion to the applied layers of dry mixes. Consumption of betokontakt is on average 0.25-0.4 kg / m2.

It is intended for processing wood, stone, metal and cork coatings only inside. It penetrates very deeply - not less than 10 mm, due to which it reliably protects the tree from bacteria, bugs, decay and the destructive action of moisture. It is considered the best in the line for highly absorbent surfaces.
Specifications:
It is obligatory to use for soft wood species - spruce, pine, as they absorb paint unevenly and the base turns out to be spotty. Apply with a brush or a special brush. One liter is enough for processing 16 squares. After drying, intermediate sanding with an eccentric sander, machine or cloth is required until no excess remains on the surface. Only then can varnish or paint be applied.
Made on the basis of alkyd resin and organic solvents. It is used for external and internal work in order to protect wood - floor coverings, furniture, walls that are not in contact with the ground, from all negative factors - bacteria, fungi, insects.
Specifications:
Shake thoroughly before application. Apply in the usual way. It is diluted with white spirit, therefore, during operation it is necessary to thoroughly ventilate the room.
In car repair for body preparation, priming is an obligatory stage of work. As a rule, this is a composition based on resins and chemical reagents, which creates the thinnest film on the metal surface that is resistant to mechanical damage, reagents and prevents the formation of corrosion.
All types of primers can be divided into 3 groups:
- epoxy;
- acrylic;
- acidic.
Epoxy work only with metal and form a dense film during application and drying. It protects against damage, fills in small chips and repels water.
Acrylic used for all types of surfaces - metal, plastic, alloys, etc. Their task is to level the surface, fill in shallow scratches and chips, increase adhesion and protect against corrosion.
Acidic - basic composition that prevents the destruction of the body from chemicals and salts. It cannot be a base for painting, it is obligatory to apply an epoxy or acrylic primer.
APP 2K Grund EP
Two-component epoxy primer containing 2K zinc phosphate. It is used to protect metal, aluminum, steel and fiberglass from aggressive chemical environments in winter. It is applied both as an adhesive coating and as an insulator for thermoplastic substrates.
