Before finishing any surfaces with suchbuilding materials, such as cement, concrete, gypsum, lime cement and others, it is necessary to treat the substrate with a special compound. Then the further finishing will turn out qualitative and will not demand repair for a long time.
Primer serves to strengthen the cladding of the claddingand treated surfaces, increasing their adhesion. In other words, this composition changes the properties of concrete, brick, slabs, which is very important, as the key to the success of any repair is precisely the increase in the adhesion of materials.
Mandatory to use in carrying outrepair work composition is a waterproofing and adhesion primer "Betonokontakt." The consumption of this product directly depends on how much the surface to be treated is porous. More porous require coating in several layers and more careful processing. Less porous usually covered with a primer once or twice, and the consumption of "Betonocontact" per 1 m2 is 0.2-0.5 kg.
"Concrete contact" is used most often before:
Considering an example of laying ceramic tileson the wall or on the plasterboard partition, it is easy to see in practice that if the primer is applied to the wall abundantly before the adhesive is applied, the tile will stick quickly and reliably.
Due to its technical characteristics,It is effectively applied when working with expanded polystyrene, gypsum boards, reinforced concrete, concrete and many other building materials, the "Betonokontakt" primer. Its consumption can be called very economical, which advantageously allocates it from a mass of similar materials.
In addition, this primer is indispensable forpreparation for repair of walls with the remains of an old tile or painted earlier by any kinds of paints. Sometimes it is simply not possible to completely remove the old tile and remove the paint layer. With the help of "Betonocontact" you can easily prepare the old surface for laying a new tile, while the quality of the adhesion of materials will be quite high.
The distinctive property of this primer is that it is ideal for poorly absorbent or non-absorbent surfaces.
The primer imparts roughness to the old ceramic tile or painted wall, in other words, some stickiness, which is necessary with such a repeated surface finish.
Unlike many other primers, thisis sold fully ready for use. The instruction suggests only to carefully mix the "Concrete contact" mixture. The expenditure for the forthcoming work is calculated according to the instructions. For work, you do not have to buy any special tools, and even the beginner will cope with it.
Work with a primer is divided into two stages. This is a preliminary preparation of the surface to be treated and a primer mixture applied to it.
It is important: never apply a primer to a dry putty!
Tip: using a spray gun, it will be much easier to apply a primer. Although you can also apply a mixture with a brush or paint roller.
When performing work, monitor the temperature inindoors. It should not be below +5 ° C. However, too hot air is also undesirable. Since the primer is non-toxic and does not have any specific odor, special protective equipment is also not needed.
Once the formulation is completely dry, you canto start finishing work. The main thing is not to allow the primed surface to be dusted, as this will cause a decrease in adhesion, and the quality of the fixing of the finishing material will suffer.
The consumption of "Betonocontact" for 1m2 is 300gram, which is considered the norm. It should be noted that the primer looks dry after 1-2 hours, although in fact it dries only 6-8 hours after application to the surface.
Acrylic primers are the most popular among builders. These are mixtures based on latex and acrylic. There are several types of primers.

When buying a primer "Betonokontakt" you should always ask the seller for a certificate of compliance, because there are many fakes.
The penetration depth of the primer can reach10 cm, while counterfeits sometimes remain on the surface and do not contribute to an increase in the adhesion of materials. Therefore, it is not worth saving, but it is better to purchase a high-quality "Betonokontakt" primer, the consumption of which is even lower than that of many other formulations.
When using a primer for interiorfinishing should be aware that it is resistant to ultraviolet light, as well as external primers. In addition, its use protects the treated surface from parasites and microbes. In addition, you will be able to save considerably, as on the primed surface the putty and plaster fall more evenly.
An important property of the primer is itscharacteristic, as a reduction in the absorbency of a brick, gypsum, wood or cellular-concrete surface. The composition strengthens the pores of these materials. It also speaks about the economics and profitability of the primer "Betonokontakt", the consumption of which is very economical, which makes it attractive for carrying out construction work of any complexity.
