Select a primer for concrete for outdoor work. The choice of primer for concrete for outdoor and indoor use. Acrylic primers for concrete

The primer for concrete, having a low cost, performs several important functions: it strengthens the base, protects it from harmful atmospheric factors and significantly improves the adhesion of finishing materials to concrete.

Rules for choosing a primer for concrete

Manufacturers and retail chains offer consumers the following types of primers for outdoor use:

• Deep penetration concrete primer (up to 70 mm), designed to strengthen the base;
• Textured primer (acrylic) with special fillers. Used in subsequent work with concrete;
• Insulating primer (silicone, epoxy and polyurethane). Scope - protection of concrete from harmful factors: chemicals, mechanical damage, temperature changes, rain, wind and snow;
• Primer for outdoor use with antiseptic additives.

Depending on the type of surface to be treated, the following concrete primer for outdoor use is offered:

• Material intended for "smooth" constructions. This type of primer is used to protect against moisture, as well as surface treatment for finishing work: painting, plastering, laying ceramic tiles and other similar actions;
• Material for surface treatment of cellular concrete: foam concrete, cinder block and foam concrete blocks. A primer of this type incorporates a silicate filler, which “closes” all the pores well and thereby reliably strengthens the concrete base.

In this regard, when choosing a soil for concrete for outdoor work, the following rules should be followed:

• The purpose of the material: strengthening the base, preparation for fine finishing, waterproofing or fine finishing with the soil itself;
• It is necessary to take into account the condition of the base: freshly poured or old concrete, dense or cellular surface. Based on this, after carefully reading the instructions, one should give preference to one or another type of soil;
• An outdoor primer may be used for indoor applications, but never the other way around.

Important advice! Contrary to popular belief, the primer composition cannot strengthen the concrete solution without the parallel introduction of special additives. Therefore, it is strongly not recommended to add it to mortars and concretes at the stage of mixing. Moreover, this action will reduce the strength characteristics of the concrete structure.

Popular brands

Trade networks of the Russian Federation offer primers for concrete with the following time-tested brands: Tikkurila, Caparol, Weber and. We have already written about the latter on our website.

Primers produced by these companies are distinguished by a high degree of concentration (1.1-1.35 kg per liter), so they can be used with equal efficiency for both smooth and cellular concrete, fixing loose surfaces and surfaces for subsequent fine (finish) finishing.

Finishing of any concrete bases begins with cleaning, preparation and surface treatment. A concrete primer (primer) must be used for both external and internal work: before pouring the screed in the room, when puttying the walls of the house and much more. Thanks to the primer layer, the applied concrete mortar adheres better to the surface and does not collapse longer.

In addition, the primer for concrete for exterior and interior work perform a lot of other functions.

Properties of primers

Despite its strength, concrete has the following "weak" sides, which can be compensated with a primer:

• The required level of adhesion (adhesion of the concrete solution to the surface). This is especially true for perfectly smooth bases, on which it is most difficult to lay not only cement-sand mixtures, but also paint, wallpaper, linoleum and other coatings.
• Protection against excessive moisture of the base. The fact is that concrete is a porous material that absorbs moisture very strongly, which has a detrimental effect on the base, accumulating and expanding in its capillaries. If the surface is covered with a primer, then it will be a kind of waterproof barrier that prevents blockages.
• Most mixtures contain antiseptic substances that prevent the formation of fungus and mold.
• Primers for concrete for painting or plastering allow facing liquids to be absorbed evenly over the entire surface to be treated.

Of course, without a primer on concrete, your house will not fall apart, but if you want the concrete coating to last longer, then primers will be simply irreplaceable. To choose them correctly, you need to decide on the types of such mixtures.

Classification of primers according to the main component

Today, the most common primers on sale are based on: polyurethane, acrylic, natural components, polyvinyl acetate, epoxy and other components. Consider the most popular of them.

Polystyrene (polyurethane) primers

For the treatment of residential surfaces, polyurethane primers for concrete are used very rarely, due to their high toxicity. Solvents that are part of such liquids are recommended to be used only for finishing facades or industrial premises.

Polyurethane primer for concrete floors is considered the most resistant to chemical and weathering, it also gives the surface high strength. This makes it the optimal component for outdoor concrete coating.

Acrylic primers

Acrylic-based mixtures are more suitable for interior work, as they are environmentally friendly and do not exude a pungent chemical odor. Such components are combined with any finishing materials and have good absorbency. In addition, acrylic compositions dry no more than 3-4 hours. If you need a primer for aerated concrete, then you should choose this particular composition. However, it is better not to use such primers for the exterior walls of the house, since such a protective layer dries too quickly in the open air.

Water based primers

Such liquids are absolutely harmless to human health, so they can be safely used in poorly ventilated rooms and children's rooms. The main advantage of water-based priming mixtures is the possibility of application to a surface that has not dried. In addition, when working with such a primer, there is no need to use protective equipment, since it does not smell. Solutions of this type are cheaper than others.

Organic primers

Compositions based on natural components penetrate well into the structure of the treated concrete surface. Such mixtures can be used at low and sub-zero temperatures. However, organic primers have the shortest service life. Such fragility is explained by the fact that they evaporate rather quickly.

You should not use this type of primer indoors, as it has a pungent odor.

PVA and epoxy primers

Polyvinyl acetate formulations dry the fastest (no more than 30 minutes), so they are recommended if you are running out of time. To improve the adhesive properties, after applying such a primer, it is better to cover the surface with an additional layer of PVA glue.

Epoxy primer for concrete is made on the basis of resins and is more often used in surface preparation for self-leveling floors. Epoxy increases the wear resistance of concrete.

Classification of primers according to the quality of the base

According to the type of penetration into the bases, two groups of primers are distinguished: deep penetration and adhesive.

Deep penetration primers

Deep penetration primers are capable of impregnating a concrete slab by 5-7 cm, so they are most suitable for deep-pore concrete. Getting into them, the primer clogs the voids, forming a durable and strong film on the surface. Due to their deep penetration properties, primers provide high adhesion, which can be achieved thanks to the latex particles included in the mixture. Therefore, such building mixtures become a good basis for lime-gypsum, gypsum and lime-cement plasters.

Deep penetration mixtures may include:

• plasticizers;
• polymer additives;
• antiseptics;
• quartz;
• acrylic and latex.

The penetrating primer is also used for the reconstruction of screeds and walls, which previously (before primers of this type appeared on the market) could not be repaired.

Healthy! It is better to apply deep penetration impregnations in several layers, the greater the thickness of such a primer, the stronger the concrete structure becomes.

Adhesive primers

Adhesive primers give a smooth surface a roughness due to the quartz sand that is part of the primers. Due to this, the adhesive properties of the treated surface are significantly increased. The adhesive primer is suitable for gypsum, polymer and cement-sand putty mixtures, as well as for finishing walls with planed wood, tiles, gypsum boards and gypsum boards.

If the walls, floor and ceiling were previously covered with putty or paint, then it is recommended to use adhesive compounds for such surfaces.

In addition, when choosing a concrete impregnation, it is necessary to take into account the manufacturer of the composition.

The best brands of primers

Construction markets offer a large selection of impregnating primers at a variety of prices. In order not to overpay and choose the highest quality and durable composition, pay attention to the following products:

• Ceresit CT 17 is a universal impregnation that can penetrate even the smallest pores of a concrete base. Does not block the processes of steam and gas exchange, due to which the base “breathes”. Thanks to the coloring pigment Ceresit it is convenient to apply. This composition is produced in two types: frost-resistant and summer. It costs about 450 rubles for 10 liters.

• Lacra is an impregnating primer based on polyurethane. Reliably protects concrete from formation of a mold and a fungus. Thanks to antiseptic additives, it is optimally suited for bathrooms, baths and loggias. The mixture costs about 500 rudders per canister.

• Knauf Tiefengrud is a universal water-repellent primer designed to prepare the substrate before laying tiles, painting and wallpapering. It has high penetrating properties, so this composition is recommended for use on super hygroscopic surfaces. The cost of such a primer is about 630 rubles per 10 kg.

• Knauf Betonokontakt is a polymer-based quartz sand dispersion well suited for poorly absorbent surfaces. The primer of this brand is used for interior work and for preparing walls and ceilings for finishing with gypsum stucco. However, such a composition is quite expensive, from 3,100 rubles per 20 kg.

In custody

Regardless of the primer chosen, before applying it, it is necessary to thoroughly clean the concrete surface, wash it with water and wait until the base is dry. Primers are available ready-made or require self-mixing. All information must be indicated on the packaging.

A concrete primer is an indispensable building mix, because surface priming is an obligatory stage in any finishing work. Thanks to this process, repairs can last for many years, and the room will receive reliable protection against mold. On the modern market there are many types of primer, which is intended for different surfaces.

A distinctive feature of primers for concrete is that they can be used to treat almost any surface. Deep penetration building mixtures are actively used to improve the adhesion of the concrete base and coating. In addition, carrying out such work makes it possible to:

• better and more efficiently distribute the final finish;
• reduce the use of finishing mixtures;
• prevent the appearance of mold or fungus in the future;
• eliminate small differences and surface defects.

Deep penetration primers

Deep penetration primer for concrete is one of the most popular. A huge number of advantages and an affordable price provide this building mix with demand and make it an excellent choice for both indoor and outdoor work. Modern building mixtures of deep penetration are a unique composition, which includes various modifiers and polymers. Most varieties also include antiseptics that prevent the appearance of fungus.

Among the main advantages of primers for deep penetration concrete, the following can be distinguished:

• the ability of the surface to adhere to various materials is significantly improved;
• reduces the consumption of finishing materials;
• enhances the effectiveness of the surface structure and penetrates into the base of the layer;
• does not allow the exit of moisture and does not interfere with the flow of air;
• absorbs dust and improves the resistance of the surface to damage;
• helps to reduce the absorbency of coatings, which leads to a decrease in paint consumption;
• allows to eliminate microcracks.

Another advantage of such a mixture is that it can be used for surface treatment, regardless of its porosity. If the base is low-porous, then the polymers that make up the primer will be able to expand the pores, and if the base is loose, they will provide narrowing.

Also, the indisputable advantage of deep penetration primers is their ease of use. Even a person who is far from construction and has never done finishing work before can carry out high-quality priming. Before starting work, be sure to clean the surface of dust, grease and other contaminants. The mixture must be applied with a lint roller or paint brush.

For the production of primers for deep penetration concrete, acrylic is used. They may also contain latex. Among the other advantages of such a mixture, one can single out the complete absence of smell, affordable price and unique antiseptic properties.

Selection rules

The quality of the ongoing construction work requires compliance with the technology of using building mixtures. Primer for concrete should be selected according to several criteria, among which are the following:

1. The type of foundation is the most important factor. If the surface is polyurethane, then the appropriate primer is used.
2. Surface strength - M150 and M300 grades are considered one of the most dense concretes, therefore it is better to use an epoxy primer for their processing.
3. The conditions under which the finishing work will take place. In the process of using a primer, attention should be paid to many factors that can affect the effectiveness and quality of the mixture, as well as its retention of its properties. For example, if the finish will take place at sub-zero temperatures, then it is better to refuse to use a deep penetration primer.
4. Operating conditions, in different places, the load on the bases may be different.
5. Additional parameters that you should also pay attention to when buying primers for concrete are chemical resistance, vibration load and others.

Before proceeding with outdoor work, it is necessary to carry out a primer treatment, which allows you to strengthen the top layer of the base and ensure its reliable protection from bad weather and other factors.

A good primer mixture for outdoor use has the following advantages:

• preservation of surface properties and increase in service life;
• providing better adhesion of the surface and the base;
• avoid contact with incompatible materials;
• weather resistance - must provide reliable protection against moisture, which falls in the form of precipitation;
• preventing the appearance of fungi and mold.

In addition, the composition of such mixtures includes inhibitors and antioxidants, which is of paramount importance when metal surfaces are involved in the finishing.

Primer for interior work

The primer for interior work should be chosen very carefully, because the quality of further repairs depends on it. Given the fact that the concrete base absorbs moisture quite poorly, mixtures containing quartz sand should be used for surface treatment. This significantly improves adhesive adhesion, which in turn affects wear resistance.

Application technology

Before applying interior primer to the surface, it is necessary to thoroughly clean the substrate from dust, dirt and other substances that may impair the properties of the mixture. The primer may only be applied to a dry surface.

After the mixture is prepared, it must be applied within a few hours. Otherwise, the product will lose its properties and will not be effective.

The primer can be applied with a brush or a small roller. The consumption level is usually indicated on the packaging, as are the cooking features. It must be diluted strictly in the proportion indicated by the manufacturer.

Thus, for maximum protection of the floor, ceiling, wall, and other concrete surfaces, it is essential to use a concrete primer to help reinforce the surface. Such building mixtures are characterized by ease of use, so that anyone can carry out high-quality priming of the base, thereby ensuring the durability of the surface.

In modern construction, concrete is the most common material. Thanks to innovative technologies, various types of concrete are produced, which are suitable for both outdoor and indoor use. In this case, the surfaces need additional processing. For this, deep penetration primers for concrete are used, which are designed to perform many functions.

When carrying out any type of repair work, priming is an obligatory step, which cannot be dispensed with. Which primer is suitable is decided in each case, taking into account the characteristics of the surface to be treated.

Features of concrete

Today, concrete is a universal building material, the popularity of which is very high. Thanks to the characteristics of the material and the technology of erecting objects, it is possible to realize the most diverse and bold ideas and design tricks.

The main feature of concrete is its affordable cost, which is low in comparison with other building materials. It should be noted that concrete is safe from an environmental point of view.

The scope of concrete is quite wide. With its help, it is possible not only to increase the level of mechanization, but also to establish automation of technological processes. And when using a concrete primer for outdoor work, you can create any architectural and building style.

The need for a primer

Everyone who has ever carried out repairs in their apartment knows very well that before the walls are puttied, painted, wallpapered, they need to be covered with a primer layer (or maybe not one). The same must be done before laying the flooring. But not everyone will come up with the question why this is done.

The main task assigned to the primer is to increase the adhesion of the concrete surface with subsequent finishing materials. In addition, the mixtures provide protection against the harmful effects of a number of external factors.

The material in the already frozen state is quite durable. However, if you do not use additional tools such as a primer to strengthen the concrete, it may collapse. This may be due to mechanical reasons. Concrete is also affected by natural external factors.

Functional purpose

As you know, concrete is a material with high density and hardness, but at the same time it contains micropores. The porous structure has both its advantages and disadvantages. In particular, if the concrete surface is left as it is, then its pronounced absorbency leads to overestimated costs of paint and varnish products.

The primer with the effect of deep penetration is a special composition that enters the micropores. This allows you to strengthen the concrete from the inside, and at the same time increase the adhesive properties. As a rule, this is achieved through acrylic polymers, which are rich in some types of deep penetration primer for concrete. When they are used, along with the strengthening effect, the absorbency of the building material is reduced.

Priming mixtures are used for exterior or interior decoration. After surface treatment, other types of finishes can be applied:

putty;

tiling;

paint and varnish products;

plaster (including decorative);

wallpaper (including liquid).

At the same time, the primer makes it possible to apply subsequent finishing materials in an even layer. Based on this, it becomes clear that the application of such compositions is a necessary and important process.

Product range

Depending on the composition of the primer are divided into several types:

polystyrene;

acrylic;

polyvinyl acetate;

epoxy;

alkyd.

Polystyrene concrete primer for outdoor (or indoor) use in everyday life is rarely used, since it is made with the addition of toxic solvents. Therefore, the scope of its application is limited mainly to the external decoration of facades or industrial premises, preferably open ones. Some specific types of paints require a polystyrene-based primer. In addition, such mixtures are applied to the plastered surface before laying the tiles.

Acrylic mixtures are widely used. And all due to the fact that they do not have a pungent odor, they are ideally combined with almost any type of finishing material and have excellent absorbency. After applying the primer, you can proceed to further finishing after 3-4 hours. Due to the environmental friendliness of the material, the interior concrete primer can be applied to the surface of any premises, including children's rooms and hospital wards. Only due to the rapid absorption and drying of acrylic compounds is not recommended for facades.

Polyvinyl acetate primer is ideal for applications where repairs need to be carried out quickly. After application to the surface, it dries within 30-40 minutes. Only before finishing it is necessary to carry out processing with PVA glue in order to improve adhesion. After that, you can start wallpapering or painting.

Epoxy primer is made from resin. It is often used when applying polyurethane flooring. After applying the composition, the wear-resistant properties of the material are significantly increased.

Solving the burning question of which deep penetration primer is best for concrete, you can take a closer look at alkyd mixtures. They are also popular in modern construction and are most often applied to the surface before painting work. Penetrating into the porous structure of concrete, the composition provides reliable protection of the material from moisture. Complete drying takes from 12 to 15 hours.

Features of choice

To make the right choice of primer mixture, it is necessary to clearly understand for what purposes it will serve - for outdoor work or whether it will be interior decoration. For the treatment of external surfaces, it is worth purchasing a special facade composition that dries for a long time. In outdoor conditions, this is an important advantage. For interior decoration, any available type of primer is suitable.

Another important point is the cost. Here it is better not to be stingy, but to purchase expensive, but reliable products, than later to "reap the benefits" from a product of dubious quality.

Fortunately, a good deep penetration primer is not always expensive and you can find an inexpensive option. In any case, it is better to trust a well-known and reliable manufacturer.

The construction market can be flooded with fakes that exist in almost any field of activity, you must first of all pay attention to the packaging, which always has the appropriate protection (holographic labels, stickers, etc.), which only the manufacturer has.

On guard of health

When buying a primer before a major repair, you should choose the one that has antiseptic properties. And it does not matter what type it is, and for what types of work (exterior or interior decoration). This eliminates the risk of fungus or mold on concrete surfaces.

This is especially true when there are small children in the family. And if for parents the price of a deep penetration primer does not matter, then when planning repairs in a children's room, you simply cannot do without this finishing material. After all, the fungus releases its toxins into the air. As a result, in such a room you can not only catch a runny nose or allergies, but also more serious diseases. And children, by virtue of the body that has not yet grown stronger, are the first to suffer.

Application features

Before applying the primer, you need to carefully prepare the surface. To do this, the old finish, if possible, is completely removed. If there are large cracks, they must be repaired. Liquid primers are usually already ready for use, dry mixes must first be diluted with water. Some types of primer need constant and thorough mixing.

It is convenient to apply the composition with a roller, as it covers a large area. In difficult areas, it is better to go with a brush. For large volumes of work, you can use the spray gun. At the same time, it is better to add more liquids in an amount of 5% of the total volume to deep penetration primers for concrete. This is done so that the mixture does not get stuck in the hoses and nozzle. Manufacturers themselves give such advice.

During the application of the composition, it must be ensured that it lays down in an even layer. After that, be sure to let the primer dry completely. The time is indicated on the package, but you can guess by the shade. If the base is weak and crumbles, the whole process must be repeated.

As many experts advise, it is better to work with a primer at a positive temperature from 5 to 25 °. As for humidity, try to keep the level no more than 65%. Otherwise, during surface treatment, the mixture will begin to foam. Polyurethane compounds are an exception.

If the concrete base is dense, then, according to the advice of many experts, a concrete contact mixture can be used. It consists of fine quartz sand, due to which the finishing materials adhere better to a smooth surface. The composition is suitable for both outdoor and indoor use.

When applying a deep penetration primer, its consumption will depend on the surface. As practice shows, for 1 sq. m will need 80-120 grams.

During processing, safety measures must be observed. Wear rubber gloves and make sure that the primer does not get into your eyes. If this cannot be avoided, immediately rinse them in warm water. To avoid such a case, it is better to work with glasses.

Issue price

As for the cost, you can find different prices on the market. Polyurethane primers occupy a more expensive niche, starting from 4,000 rubles. Acrylic blends are more readily available. For example, the brand "Optimist g101" is sold at a price of 300 rubles per 10 liters. The cost of KnaufTiefengrund and Ceresit CT 17 is just over 600 rubles for the same volume. The primer under the brand name "Prospectors" is sold in the region from 350 to 500 rubles for the same 10 liters.

Repair work will be inexpensive if you initially choose the right deep penetration primer for concrete. Such compositions not only increase the life of the surface, but also make subsequent finishing cheaper.

Primer for concrete is an indispensable material for finishing concrete surfaces. The primer performs many important tasks, ignoring which will not allow you to perform work at a high quality level.

Functions of primers

Products from standard concrete are prone to gradual destruction and are subject to the influence of natural factors. The primer is largely able to prevent or slow down the influence of the external environment.

Possibilities of primers:

1. The primer ensures the uniformity of the coating, as it penetrates into all, even minor, pores. On a primed surface, it is easier to apply subsequent finishing materials, including putty, varnish, paint, wallpaper, linoleum, etc.
2. Thanks to the primer, a normal level of adhesion (adhesion) between materials is ensured.
3. The primer for concrete makes the surface layer of the material stronger. This does not mean that without it, concrete will necessarily fall off in pieces. However, even if the concrete begins to crumble, this will lead to peeling of the finishing materials.
4. The primer protects the concrete surface from adverse environmental factors, including moisture, wind, chemicals, mold and fungus.
5. The primer composition allows you to save on the consumption of the material applied later (glue, varnish, paint, etc.). The reason for savings is that the primer will fill all the pores and cracks.
6. A primer for concrete not only prevents excessive moisture in concrete, acting as a waterproofing, but also protects the material from excessive dryness.

Thus, in finishing work, the use of a primer is mandatory. Without priming, it is impossible to ensure the proper quality of the repair.

Classification of primers by composition

Below are the characteristics of common types of primers:

1. Polystyrene primers. These compounds are rarely used in everyday life. The fact is that such soils include toxic solvents. Polymer compositions are used in industrial premises or for finishing facades. Also, a polystyrene base is required for some specific types of paints. Typically, polystyrene primers are applied to plaster - under tiles or paint.
2. The most common type of primer is made on the basis of an acrylic component. The advantages of acrylic compositions include the absence of a pungent odor, compatibility with any type of finishing materials, as well as excellent absorbency. As a rule, after 3-4 hours after concrete processing, finishing work can begin. The environmental friendliness of acrylic allows the use of such primers for any premises, including children's rooms. However, acrylic is undesirable for exterior walls, as it dries too quickly.
3. For quick finishing of the premises, polyvinyl acetate primers are used. They dry within half an hour. After that, to improve adhesion, the surface must be treated with PVA glue.
4. Epoxy primers are made from resin. Most often used when working with self-leveling floors. Allow to significantly increase the wear resistance of the material.
5. Alkyd primers are also in demand. They are applied to the concrete surface before painting. Alkyds penetrate into the pores and protect the concrete from moisture. The surface drying time is approximately 12-15 hours.

For the processing of aerated concrete, soils with polymer content are considered the best option. Primers for aerated concrete can not only protect the material from moisture, but also strengthen its structure.

Classification of primers according to the quality of the base

Priming compositions are also usually distinguished based on the characteristics of the base, namely: its porosity and level of friability. According to this indicator, primers can belong to one of three groups:

1. Deep penetration primer for concrete with increased porosity. Moreover, there are not only many pores in such concrete, they are also deep. Important note: the surface should not be too loose. Deep penetration primers can penetrate approximately 5-7 millimeters deep into concrete. Such compositions are characterized by increased adhesive capabilities, which is especially important in the presence of deep pores. Good adhesion is achieved due to the latex particles, which adhere to each other the concrete surface with the finishing material.
2. Impregnating primers are best used to protect old loose concrete (for example, for renovation purposes). Impregnations are also relevant for highly porous surfaces. The impregnating composition contains a special binding element that holds all the small particles of the material together. The most expensive types of impregnation can strengthen walls and screed, which were previously considered beyond repair. In relation to impregnations, the principle applies: the more it is applied, the stronger the concrete structure will be.
3. Adhesive primers are designed to create a special invisible film that will provide better adhesion of dissimilar materials. Adhesive compounds are especially relevant for very smooth concrete surfaces that have previously been treated with putty or painted. It is also possible to apply an adhesive primer before plastering if the plaster layer is not too thick.

Note! Depending on the condition of the coating, its porosity and roughness, the consumption of the primer composition can vary between 200 and 300 grams per 1 m2.

1. Regardless of the type of primer, it is recommended to choose a composition with antiseptic properties. This will prevent the concrete from molding. If the room will be operated in conditions of high humidity, you need to choose a primer with a high concentration of antiseptic.
2. When buying soil, it is necessary to take into account the place of its use - outside or inside the room. For exterior walls, it is recommended to use a facade primer. Its advantage is that it does not dry out too quickly, which is important for outdoor conditions. For internal walls, any type of soil can be used.
3. It is necessary to take into account the characteristics of the finishing material. Manufacturing companies offer various types of soils designed for specific types of materials. The compositions differ in consistency and constituent components.
4. It is better to buy a primer under an expensive brand than a cheaper, but little-known product.
5. A primer for a concrete floor or wall may well be a fake. You should pay attention to the protection against counterfeiting, as well as the date of production of the goods. An expired or falsified composition will not allow to ensure the quality of the work.

This article has all the necessary information with which you can decide which concrete primer to buy. Properly selected composition will provide reliable protection of concrete from environmental factors, as well as allow high-quality finishing work.
