Technical characteristics, application and consumption of concrete contact. The use of concrete contact - instructions for application and technical characteristics of the compositions Which concrete contact is better to use for outdoor work

Before finishing the walls and ceiling, you need to carefully prepare the surface. To keep the top coat well, use a primer. Previously, builders primed in different ways, but we see that the paint and tiles have begun to peel off or have already collapsed. In cheap new buildings, workers sin with a minimum consumption of primer, which also leads to sad consequences.

Concrete-contact will help to prime qualitatively and for a long time. Not all builders want to work with him, as they have heard different stories and are not ready to part with proven methods. But practice proves that real BC is better than a conventional primer, if you follow all the rules for its use. The hardened surface of the concrete becomes smooth, and therefore it has low adhesion, that is, the ability to stick together. This is why tiles, plaster and paint fall off quickly. Concrete-contact is a special type of primer that promotes better contact between the finish and the smooth surface of the concrete, old tiles or paint. The BC contains fine particles of quartz sand, which increase the adhesion of the base and finishing material.

The technical characteristics of the concrete-contact primer depend on the composition. There are primers with a sand fraction of 0.3 and 0.6 mm. The finer the grains of sand, the lower the consumption. The choice is influenced by the field of application: BC with fractions of 0.3 mm is enough for puttying, and 0.6 for plastering. This primer is made on the basis of acrylic, which avoids a strong smell, and it also dries quickly. Usually BC has pink color, so unscrupulous workers cannot save on it. After all, it is not uncommon for the primer to be heavily diluted with water or applied loosely. Tex offers BC that blushes on the surface so you can control the evenness.

Application features

What homegrown builders don't know is that every primer has a limited area of ​​application. The price of concrete-contact is higher than that of a conventional primer, so before buying, figure out if you need to increase the contact between the coating, and if the base absorbs moisture. To do this, sprinkle water on the surface, if the liquid is not absorbed or absorbed slightly, the use of concrete contact will be justified. If the base is rough, better fit a mixture of deep penetration and it costs less.

In some stores, sellers position concrete contact as a miracle primer, which is used for brick, old plaster and putty, but this is not so. If you have a perfectly smooth brick, they may be right. Otherwise, look for another primer. Read the description on the package, it is often more useful than consulting with an unknowing person. The characteristics of concrete-contact are such that its use is justified only for smooth and almost non-absorbent surfaces.

Base types:

• monolithic concrete and blocks;
• old tiles;
• oil or alkyd paint.

Coating types:

• gypsum, gypsum-limestone plasters and putties;
• tile adhesive.

If you need to process different surfaces inside and outside, the concrete-contact primer Universal is suitable for you. BC produced by the company Prospectors will withstand the outdoor environment. It includes additives that increase moisture, frost resistance and antiseptic properties. If the amount of work is large, by choosing the appropriate composition, you will not only strengthen the base and extend the life of the finish, but also save money.

Large companies develop primers specifically for their materials. This does not mean that the use of products from one manufacturer is mandatory, but if you have such an opportunity, use it. Prospectors and Knauf firms have a line of building materials. Such products are tested jointly.

Application technology

1. Do I need to prepare the surface?

Remove old coating if possible. It is convenient to clean the plaster and putty with a metal brush, the whitewash must also be removed. Clean the base excess fat soda or detergent. So nothing will interfere with reliable contact between the primer and the base.

2. Is concrete-contact diluted with water?

In any case, this is a violation of the technology of work. Before use, mix the primer thoroughly with a mixer so that there are no lumps in it.

3. How many layers can be applied?

1-2 layers will be enough.

4. What is more convenient to apply?

The use of a roller or mechanical spray allows you to reduce consumption and perform better work. You can also use a brush or spatula if needed.

5. What is the consumption per 1 m2?

The average consumption of concrete-contact is 0.2-0.5 kg. The higher the moisture absorption of the material, the more primer you need to spend.

• For monolithic concrete and concrete slabs- 0.35-0.2 kg.
• For tiles - 0.15-0.25 kg.

6. At what temperature is it applied?

The temperature must be above +5 and below +25 °C. It is better to clarify this information on the packaging, since the characteristics of concrete-contact vary depending on the manufacturer.

7. After what time can I continue?

It all depends on the manufacturer, the average drying time is 6 hours. But it is better to start subsequent work within a day so that dust does not appear on the plane. Rinse brushes and rollers immediately with water. After drying, high-quality concrete contact will be difficult to clean off.

Price

The table shows the average prices for betting shops as of the end of 2015. Don't buy blends expensive manufacturers at a low cost. Unfortunately, in the Russian market building materials there are a lot of fakes, so it's easy to buy a BC with the characteristics of a regular primer or even worse. Sometimes you can stumble upon a quality product from lesser-known companies at a low price, but before buying, read the reviews, or rather, conduct a trial priming.

Do not skimp on the primer composition, it will be a shame if a piece of the wall flies off from drilling or hitting with a hammer. See the expiration date, it usually ranges from 6 months to 1 year, and product certificates. If you have a large amount of work to do, buy one pack and test it on a small area.

Concrete contact primer is a special composition used for gluing standard finishing materials to rather unusual surfaces. Roughly speaking, this is not even a primer, but a kind of glue used to create special conditions that allow standard glue to stick to each other those materials that cannot be glued under normal conditions. This may be the need to glue tiles to metal or glass, etc. - the possibilities are quite extensive. Moreover, after applying the concrete contact primer, the material can be glued using almost any type of glue.

After the completion of the repair work, many of us had to deal with such problems as peeling wallpaper sheets or peeling paint. The reason for these shortcomings is the lack of proper preparation of the base before finishing work, which in turn significantly affects the adhesion (adhesion) of materials. It is in ensuring the proper degree of adhesion that the role of the primer lies.

At the moment, there are many types of primer. Some of them are designed for processing a specific type of surface, such as wood or metal, while others are considered universal and can be used on any surface, regardless of the material. Concrete contact primer refers just the same to universal primers and can be used to work with brick, drywall, concrete, tile and many other materials. In addition, it is worth noting that there are special types of concrete contact that belong to compositions with local application, that is, according to the instructions, they are used exclusively for processing the specified type of surface, for example, for wood or metal. However, as practice shows, these separations are very conditional and, in principle, such concrete contact can also be used on other surfaces, although adhesion for the specified composition as a whole will be somewhat better.

In particular, concrete contact can be used for the following works:

• processing of floor slabs for subsequent screed;
• preparation of ceilings for finishing with lime, etc.;
• preparation of the base for the screed.

And this is not all areas of application of concrete contact. In addition, the mixture can be used when installing a self-leveling floor, finishing plasterboard surfaces, etc.

Special mention deserves the fact that, due to the properties of the concrete contact primer, it is not necessary to dismantle it to change the old finish to a new coating. The new finish can be attached directly to the old coating, after the latter has been treated with concrete contact.

Material Specifications

At present, there are four major specifications of this material, which affect the quality of the work performed:

1. Durability - the technical characteristics of the concrete contact indicate that the properties of the composition are preserved for eighty years. For interior decoration this term is more than enough, because repair work are usually carried out with much less frequency.
2. Drying time - after applying the concrete contact, subject to the instructions, the surface is ready for further finishing in two to three hours.
3. Moisture resistance - concrete contact, in fact, creates additional waterproofing, since when applied to the surface, this composition forms a waterproof film.
4. Material consumption - an approximate rate per square meter. meter is from two hundred to four hundred grams. It should be borne in mind that these indicators are very conditional and vary depending on the technical characteristics of the composition itself, as well as on the characteristics of the treated surface.

Features of using concrete contact

One of the advantages of concrete contact is considered to be the fact that this material is extremely simple and convenient to use and can be applied by a person without special skills.

So, in order to get started, you must first prepare the surface on which the composition will be applied. Let's start with the fact that for all adhesive materials, including concrete contact, there are recommendations for application, each of which begins with cleaning the surface. It is from the cleanliness of the treated surface that, subsequently, the quality of the adhesion of materials will largely depend. Depending on the type and degree of contamination, the area to be prepared can be swept or washed thoroughly.

It is worth noting that for cement and concrete surfaces, simple cleaning will most likely not be enough, so they are best cleaned using a standard deep penetration primer, which will not only eliminate dust and hold the outer layer together, but also become an obstacle to moisture, which, in turn, turn, will help to significantly reduce the consumption of the mixture used.

After the cleaned surface dries well, a concrete contact primer is applied directly to it. This is best done with a wide brush, but a roller will work too. The most important thing is not to allow the slightest omission. IN individual cases, for example, when the area to which the mixture is applied has visible defects, the surface will need to be treated twice. Since all the gaps after drying the walls are visible to the eye, it will be quite easy to see and eliminate the shortcomings.

It should be noted that the finishing of the treated surface should be carried out immediately after the concrete contact primer has completely dried, since the slightest delay can lead to new contamination and, as a result, a decrease in the quality of adhesion. That is why, before applying the composition, it is necessary to realistically assess your strengths and cover with concrete contact only the area that you can veneer at a time. If you are still forced to take a break between the drying of the concrete contact and finishing, not exceeding two days, the treated surface will need to be treated with a deep penetration primer before work. If more than two days pass from the moment of processing, the surface must be re-coated with concrete contact.

To improve adhesion with substrates such as tiles, paint, monolithic concrete or a glossy surface that has insufficient adhesion and minimal moisture absorption, a water-dispersion primer "Concrete-contact" is used. It is characterized by a high rate of resistance to alkali, makes a rough surface from a glossy surface. This ensures the quality and reliability of the work performed. The primer "Concrete-contact" is based on quartz sand and polymers. Thanks to these components, adhesion increases several times.

Specifications

During construction and repair, various situations related to poor adhesion may occur. This feature is possessed by surfaces that have poor adhesion to the base. For example, these are painted or glossy materials. Then the primer "Concrete-contact" is used. It increases adhesion and improves the quality of the work performed. It also dries quickly, which will allow you to perform subsequent work in a couple of hours.

The primer is steady against moisture and climatic atmospheric loadings. It is a waterproof material. After application, a waterproof film forms on the surface. According to the manufacturers, the service life of the finish reaches 80 years. This gives confidence in a reliable repair, and also allows you to guarantee the quality of the final result.

purpose

The features of the presented agent make it possible to use it both to improve adhesion and for a waterproofing effect. The properties of the primer "Concrete-contact" are such that it is rational to use it only for smooth surfaces that do not absorb moisture. For a rough base, the usual means of deep penetration is suitable. It will cost less and will be more rational for absorbent surfaces.

A primer is used inside and outside the premises, which allows the installation of various finishing materials. A popular tool is the primer "Concrete-contact" from "Prospectors". It contains special additives that allow you to withstand atmospheric loads. They increase moisture and frost resistance. It also contains antiseptic components. Thanks to the use of this material, the finish has been used for many years.

Prospectors and Knauf are leaders in this area. Their products are tested together, they have proven themselves on the positive side in the quality market.

Purpose of the primer

The main purpose of the primer "Concrete-contact", the use of which increases the adhesion of the surface, is to improve its absorbency. For example, applying adhesive to tiles or monolithic concrete will not work. These materials do not absorb moisture well. In this case, "Concrete-contact" is ideal.

Previously, in the process of repair, builders used the so-called bandage to prevent premature shedding of plaster. It was superimposed on concrete in the form of a fabric mesh using PVA glue. After that, the plastering process took place. This procedure took a long time. Repairs were becoming quite difficult. The work is greatly facilitated by the use of the primer "Concrete-contact". The principle of its operation is the same, only to work with it faster and more efficiently. The primer is used both indoors and outdoors.

Manufacturers and cost

Good, high-quality manufacturers are companies such as Ceresit, Knauf, Prospectors. The average pricing policy of the funds presented does not differ much. Prospectors' products are sold in containers of 5 and 20 kg. The cost is, respectively, 500 and 1400 rubles. The manufacturer Knauf presents the primer for sale in packs of 5 and 20 kg. The price is, respectively, about 800 and 2500 rubles. Ceresit manufactures the presented solution in containers of 5 and 20 kg worth 500 and 1000 rubles.

These companies have been on the market for a long time. During this time they managed to prove their quality and reliability. Therefore, when using the products of the presented brands, the durability of the finish is guaranteed.

Consumption

When using the primer "Concrete-contact", the consumption will depend on many factors. This includes the quartz sand fraction that was used in this primer. It can be 0.3 and 0.6 mm. Also, the consumption is influenced by the type of surface, areas of application and method of applying the solution. The average consumption of "Beton-contact" ranges from 250 g/m² to 400 g/m².

When choosing a primer, it is worth considering what the subsequent work will be after its application. A primer with a smaller fraction of quartz sand is suitable for application under putty. It is used for thin layer work. A primer with a larger fraction is ideal for thick-layer plastering. Because of this, its consumption increases by 1.5 times.

Surface preparation

Application of the primer "Concrete-contact" is carried out in accordance with construction requirements. It is applied to a clean, dust-free surface. If the base is painted, it must be degreased. The concrete base must be checked for strength before applying the primer. If there are loose particles, they must be removed.

The technical characteristics of the Prospectors primer, as well as similar manufacturers, will allow them to be used to strengthen the bases. After the film covers the surface, the primer dries for about 3-4 hours. Then you can proceed to the subsequent finishing work.

If the base is very loose, it will be more effective to open it initially with a deep penetration primer, and then with "Concrete-Contact". Thanks to this action, it will be possible to provide a sufficiently strong foundation.

Application features

After preparing the base, the stage of applying the Concrete-Contact primer to the surface is suitable. It must be thoroughly mixed after opening the jar. More comfortable is the method of application when using a roller, as well as a brush, maklovitsa.

The mixture can be applied mechanically. Its consistency is similar to paint, so working with it will be easy. It is applied in 1-2 layers, no more. The pigment in the primer is white or pinkish. This allows you to clearly see the machined surfaces of the object.

After application, you need to wait 3-4 hours for the primer to dry. After that, you can continue with subsequent work. The lower the temperature, the longer the drying process takes. It is not recommended to apply a primer if the temperature is below +5 ºС. It will not provide sufficient protection of the base from moisture and good conditions to dry the primer.

If the temperature is below zero, it is impossible to work with "Concrete-contact". Do not apply a primer to the wall if the temperature exceeds +25 ºС. After surface treatment, it is not recommended to leave it unfinished for a long time. Due to the fact that dust will settle on the base and various substances will get into it, the quality of adhesion will decrease.

Having considered the application technology and technical characteristics, we can conclude that the presented product can be used at the stages of complex work. It can be used by both professionals and beginners in the construction business.

Experts recommend when choosing a primer to take into account further types of work. It is also worth paying attention to the square of the object. You need to purchase products from trusted brands, pay attention to the production time, so as not to buy a fake.

Having considered the features of the primer "Concrete-contact", as well as the methods of its application, everyone will be able to use this tool when performing finishing work.

Modern primer Betonokontakt is a high-quality material that contributes to the creation of durable and fully prepared surfaces for the application of building materials.

Impregnation of walls, slabs, partitions and ceilings with Betonokontakt allows you to connect materials of different structures, as well as in the process of diffusion changes to increase the strength and resistance to moisture of the treated surfaces themselves.

Specifications

The special dispersion primer Betonokontakt of the polymer type incorporates quartz sand, which gives the material the following features:

• high adhesion of the fastened surfaces;
• ease of application without the use of special tools;
• drying speed;
• increased degree of resistance to moisture;
• minimum water vapor permeability;
• ease of preparation and use.

The composition of the soil Betonokontakt allows you to use it not only for internal works but also outdoors.

Material Features

• the standard drying time of the soil is about three hours;
• high rate of waterproofing - when dried, the acrylic type of adhesive primer forms a high-quality moisture-proof film. When using a solution for concrete screed no need to carry out waterproofing measures;
• durability - the guaranteed service life of the surface impregnated with Concrete contact is about 80 years;
• the indicator of standard consumption per square meter of the treated surface is from 0.2 to 0.4 kg. and may vary depending on different conditions.

Application area. Why is it needed?

The primer Betonokontakt is perfectly combined with low-porous surfaces, and also holds well on oil paint, concrete tiles, finishing brick, monolithic and iron concrete, sand concrete and building bricks.

The direct purpose of the primer Betonokontakt is the need to increase the adhesion of surfaces that have a weak ability to absorb moisture. A material such as monolithic concrete poorly deposits almost any building mixtures on itself, which makes the use of Betonokontakt very appropriate.

Until recently, a kind of construction bandage was used for this purpose, which consisted in gluing a fabric mesh onto a concrete base with a PVC fabric mesh. After drying, a layer of plaster was applied to such a grid (read about, and). Now this inconvenient and lengthy process has been replaced by the use of Betonokontakt.

In addition, the composition of the soil Betonokontakt allows you to use it not only for indoor work, but also outdoors. It is allowed to apply a primer on metal and even wooden surfaces.

Application instructions

Works on applying a primer with a deep type of penetration of the Betonokontakt category are simple and do not require the use of special tools:

• thorough cleaning of the treated surface from exfoliated fragments, dirt and dust;
• pre-treatment of surfaces with a conventional primer is allowed, which will remove dust and promote binding of the surface layer;
• using a brush, roller or spatula, apply Betonokontakt to the prepared surface.

Betonokontakt primer must be applied to the surface evenly in a thin layer. Further, the layer needs to be dried, after which further work can be carried out.

It should be taken into account that the time interval between the application of Betonokontakt and the subsequent surface finishing should be kept to a minimum.

Common brands

The modern building materials market is able to offer consumers several types of Betonokontakt. The most common and popular brands of such a primer include:

Betonokontakt "Prospectors" on a latex basis from BASF

For the initial treatment of hard substrates that do not absorb moisture well and before applying gypsum, lime-cement, gypsum-lime and other types of plaster. May be used as a bonding primer for laying tile adhesive and over old tiled flooring. Used at the stage of pre-treatment of plasterboard structures for cladding ceramic tiles. Concrete contact "Prospectors" is tinted to visually highlight the areas already treated with the composition. The consumption of concrete contact per 1 m2 is about 250 gr.

Betonokontakt "Feidal" for interior work

Allows pre-treatment of dense, non-absorbent indoor substrates, presented monolithic concrete, massive concrete ceilings, concrete blocks for applying gypsum, lime-cement and other plasters. The original German formulation of Betonokontakt makes the treated surface "breathable" and environmentally friendly, and the pink color allows for visual control of the application.

Concrete contact "OSNOVIT T-55"

Promotes the formation of a textured rough surface. In the process of freezing and thawing, it retains its properties, which facilitates transportation and storage in winter. Allowed to use in temperature regime 5-30°С heat. Consumption per 1 sq. m. is about 450 gr.

concrete contact "Knauf"

Allows you to process dense, smooth, slightly absorbent and non-absorbent substrates for gypsum plaster. It is allowed to process plasterboard sheathing (read how to properly putty plasterboard) and surfaces of polystyrene foam boards. The polymer type dispersion with quartz sand is used for interior work. Consumption per square meter is about 0.350 kg.

Betonokontakt "Сeresit CT-19"

Contributes to the processing of smooth mineral, as well as predominantly concrete foundations vertical orientation for the application of cement-sand or gypsum plaster compositions and putties. Preparation of bases for any tile adhesive is allowed. Used for interior work, does not contain dyes and solvents. Differs in ecological safety and is completely ready for use.

Repair is not always an easy process. Often, difficulties, albeit minor, can arise even for professionals. What can we say about "ordinary" citizens.

The most problematic in any repair is the finishing of smooth surfaces, namely walls and ceilings. Simply covering or plastering a concrete wall is often not enough. Quite often there is a situation where Decoration Materials simply flake off and fall off in ugly pieces.

Such a phenomenon is highly undesirable. At least what will happen after this will be less enthusiasm. Not to mention how much effort and time it will take to correct errors.

But, as you know, progress does not stand still. And it was to solve such problems that Betonokontakt was created. He can literally save your repair. When using this wonderful material, you can forget about flying tiles or peeling wallpaper.

This is a truly innovative and technological material, made taking into account all the possible needs of the end user.

The composition of "Betonokontakt"

"Betonokontakt" is a complex material. It is based on materials such as:

• cement;
• polymer fillers;
• sand;
• specialized additives (for different manufacturers they may vary slightly).

It should be noted that all components are absolutely inert, hypoallergenic and environmentally friendly.

The main characteristics of "Betonokontakt"

Obviously, the areas in which the Betonokontakt primer can be used, although not unlimited, are great.

The use of "Betonokontakt"

• "Betonokontakt" is intended for use on any surfaces with reduced absorbency. So, for example, concrete absorbs moisture slightly, which leads to poor adhesion of finishing materials with it.
• Allows you to refuse during the repair from additional work, such as fastening a fabric mesh under plaster. Which in turn reduces the time spent on the process of finishing the walls. It does not require any special skills. And also allows you to increase the durability and wear resistance of finishing materials.
• The primer is a versatile material adapted to various environmental conditions. This allows you to use it not only in various rooms, such as rooms, kitchens, bathrooms, but also during outdoor work. In this case, "Betonokontakt" must be applied before facing works or using decorative plaster.
• The ability for deep penetration and the structure of the material allow it to be used on surfaces of any configuration.

Features of using "Betonokontakt"

To work with "Betonokontakt" does not require the development of certain specialized skills.

As a preparation of the surface for work, it is only necessary to clean it from contaminants and dry it. On a damp and contaminated surface, "Betonokontakt" will not "stick".

If necessary, the primer can be used in two or more layers. Allow the first coat to dry for two hours before re-applying.

Apply the solution to the surface in a thin, even layer. This does not require any specialized equipment. For this purpose, a wide brush or a roller with a medium-length bristle is great. In the absence of a tool, a home-made maklovitsa is quite suitable.

For further work, it is necessary to wait for the complete drying of "Betonokontakt". Depending on the environmental conditions, this will take no more than four hours.

Attention! To avoid undesirable consequences, mark the required time interval. Do not check "readiness" by touch - sensations can be deceiving.

To achieve maximum efficiency, it is not recommended to make the interval between the drying of the primer and further finishing work more than twelve hours. The manufacturer recommends continuing work immediately after the primed canvas has dried. This is due to the possibility of accumulation of dust and construction debris on the primed surface. Which can adversely affect the adhesion of materials.

For convenience of work and achievement of maximum efficiency, it is recommended to apply Betonokontakt to the surface as late as possible in the evening. At the same time, finishing work should be started the next morning.

"Betonokontakt" is an economical material. For processing one square meter surface will require no more than 0.3 kg of the mixture.

During the purchase of material, it must be taken into account that the consumption directly depends on the characteristics of the surface. The higher the porosity of the base, the more primer will be required. Thus, it turns out that the consumption of the primer "Betonokontakt" when working with brick surfaces can increase up to one and a half times. This is due to the presence of numerous pores, chips and cracks on the base material.

When working with plasterboard surfaces, the consumption of the mixture can be reduced by up to two times. At the same time, it is advisable to use Betonokontakt on these surfaces before facing with tiles or stone.

Among other things, the following advantages of using the Betonokontakt primer can be distinguished.

1. The mixture can be applied directly to concrete, reinforced concrete, drywall, paints and varnishes or even tiles. That is, there is no need to remove the old top coat.
2. There are two types of fractions - 0.3 mm is used before puttying and 0.6 mm before using plaster.
3. Prevents saturation of the surface with vapors and liquids
4. Working with "Betonokontakt" takes a relatively small amount of time.
5. Prevents the emergence and spread of fungi and mold.
6. Does not cause allergic reactions.
7. Has no toxic effect.

Despite the large number of advantages, working with Betonokontakt requires compliance with a number of rules.

• When applied to old finishing materials, it is necessary to make sure that there are no "swollen" areas. If there are any, remove them in advance.
• Prepare the solution strictly following the manufacturer's instructions.
• In advance, if necessary, "practice" in applying the composition on a small surface.

Storage rules for "Betonokontakt"

You can buy a primer "Betonokontakt" in almost any hardware store. At the same time, a wide range is presented to the attention of consumers.

"Betonokontakt", ready for use. Sold in plastic container. Weight ranges from 5 to 40 kg. When choosing just such an option, it must be remembered that in an open container the solution may dry out and become unusable. Based on this, it is advisable to purchase several containers of small weight. In the event that the composition of the container is not completely used up, it is necessary to ensure maximum tightness. The approximate shelf life of the finished mixture is one year from the date of manufacture. The manufacturer must indicate this date on the packaging. During storage, it is also necessary to pay attention to the ambient temperature. It should be in the range from +5 to +30 degrees Celsius. The finished mixture during storage is extremely unstable to freezing. It can lead to a complete loss of material properties. Direct sunlight also has a detrimental effect on the finished Betonokontak.

There is also a "dry" version of the primer. It is also sold in buckets or bags with various packaging. Such a mixture is less susceptible to external influences. As for the method of preparation - it is indicated directly on the package.

Betonokontakt should be purchased only in specialized stores. This is one of the guarantors of the quality of the material.

Before purchasing, it makes sense to make sure that there are certificates for this product. In the absence of a certificate or if poor-quality packaging is found (for example, mint or without marking), it is necessary to refuse to purchase at this outlet.

After opening the package, you need to make sure that the composition is homogeneous. The presence of lumps indicates poor quality or expired.

All surfaces should be treated in several stages (parts). This will achieve the highest quality and uniform application.

Popular manufacturers of "Betonokontakt"

To date, the market is represented by "Betonokontakt" of various manufacturers. There are mixtures of both imported and domestic production.

The main difference between the primer of imported and domestic production is its price. At the same time, the technical characteristics are almost identical.

The most popular are mixtures of the following manufacturers:

It should be noted that the main component of the Betonokontakt primer for all manufacturers is quartz sand. In this case, the presence of other components is possible. So, for example, some manufacturers make acicular quartz, which differs from quartz sand in its texture. The introduction of additional components allows you to increase the adhesion of materials.
