Primer betonokontakt: main characteristics and features of

Conducting capital or cosmetic repairs involves the use of certain finishing materials that are applied to the surface of walls and ceilings. In order to keep the finished coating on a vertical or horizontal surface for a long time, the primer Betonokontakt is used.

In this article we will talk about what such compositions are, as well as about what purpose and how they are used.

Application features

One of the compositions most popular today for impregnating concrete surfaces is the primer of deep penetration Betonokontakt. The main purpose of the composition is to improve the adhesion of concrete walls and finishing materials.

The primer is a mixture of acrylic, cement, sand and a number of additional components that provide the required degree of adhesion. Understand the meaning of the composition will help comparison with a sandwich. The sausage will not stick to the piece of bread, but everything will be different if the bread is spread with butter. In the case of walls, Concrete Contact performs the function of oil.

The surface of the concrete walls is smooth even in those areas where reinforced concrete was cut with diamond circles. Therefore, a layer of finishing materials on it is poorly maintained and after a short time it crumbles. In order to ensure the proper degree of adhesion, it is necessary to create a microrelief on the wall surface.

The application of a special priming composition forms a relief, for which later plaster, tile glue, liquid wallpaper, etc. can catch on.

For the creation of the relief in the composition of the primer meets fine sand, which, as you know, has excellent abrasive characteristics. As a result, after treating the walls with Betonokontakt, the surface feels like fine-grained sandpaper.

Important: This category of primers can be applied not only on the surface of concrete, but also on the surface of plasterboard structures. Drywall after such processing not only gains additional adhesion, but also becomes much stronger. The same method of pre-treatment will be relevant in relation to the previously painted or linseed-treated walls.

Soil Betonokontakt is made in two versions:

• with 0.3 mm filler fraction (used to prepare the surface for subsequent puttying);
• with 0.6 mm filler fraction (applied before plastering).

Composition and performance properties

The composition of the primer Betonokontakt consists solely of environmentally friendly and safe components, and therefore can be used in the finishing of any premises, regardless of their purpose. This finishing material has no pronounced odors, and, in addition, after drying, the finishing material does not form a vapor-tight film and the walls can "breathe".

Among the distinctive performance characteristics of Betonkotakt, the following qualities can be noted:

• small, in comparison with analogues, the time required for drying;
• hydrophobicity;
• vapor permeability;
• resistance to the formation of mold;
• reducing the consumption of finishing materials;
• reliability;
• durability;
• affordable price.

On the market, Betonokontakt is represented by a wide range of products from domestic and foreign manufacturers. Despite the fact that there is a GOST on Primer Betonokontakt, the list of components may vary depending on the technology used by the manufacturer.

The composition of Betonokontakt from domestic manufacturers by and large repeats the recipe of a traditional water-dispersed acrylic primer. A characteristic difference is the content of fillers of particle size distribution. Moreover, for staining the treated surface, the composition may contain pigment additives.

Because of its cheapness, marble flour is often used as a filler, which, incidentally, has virtually no effect on the quality of the finished finish. The products of some brands contain not marble flour, but real quartz materials. However, the cost of production of such primers is much higher, and therefore their price is high.

Important: The primer composition is such that Betonokontakt can not be stored at sub-zero temperatures, and also can not be applied to the frozen surface.

Application technology

Instructions for applying a primer is not difficult.

Nevertheless, it is necessary to comply with all technological requirements, since the quality of the finished result depends on them.

• At the initial stage, the treated surface is completely cleaned of dirt and dust. It is especially important to remove all dust if diamond drilling of holes in concrete has previously been carried out. You should also clean the fatty contaminants, as they prevent the penetration of the soil into the surface of the concrete.
• If the primer is applied to old walls, it is mandatory to turn off the power supply in the room.
• Immediately before application, the solution must be thoroughly mixed in order to lift the sediment from the bottom of the container. In addition, in the process of processing the walls with your own hands, we also do not stop mixing the solution so that it is homogeneous and does not precipitate.
• Apply the solution to the wall with a velor roller or with a brush with one or two layers of paint brush.

Important: processing of concrete with a primer is possible at a temperature not lower than + 5 ° C.

Material consumption and time required for drying

On average, the consumption of primer Betonokontakt on 1m2 is up to 0.3 kg of primer. Knowing the parameters of the treated surface, it is easy to calculate how much solution will be needed for the planned work.

The consumption of the solution can also be determined by the density of the concrete, if the surface with a large number of pores, the flow rate can double, as it will be necessary to apply two layers.

A few hours are enough to completely dry the primer. But, if the air temperature in the room is different from room temperature and the moisture content is more than 60%, the process can last a day.

Conclusion

Now you know what the operational and technical characteristics of Primer Betonokontakt. It remains to select and purchase a suitable tool and thus ensure the high quality of the finishing works.
