Ремонт является ответственным процессом.He requires the master of the corresponding knowledge and skills. During the finishing work, it is important to properly prepare the substrate for applying the finishing layer of the material. For this, various means are used to increase adhesion. In this case, the trim fits snugly against the surface, firmly grasping it.
One of the most popular means of repair is "Concrete contact". Specifications and the features of the primer presented will be considered below.
Modern building materials are differentuniversality. Their qualities are constantly being improved. Today, it was possible to combine materials that could not previously be combined. For this purpose, a special a primer "Concrete contact". Technical characteristics (GOST 28196 regulates the features of the drug) should be considered before application.
"Concrete contact" covers the surface of thinfilm. It becomes possible to glue the tile to the metal, glass to the wood. Primers are treated with walls, ceiling, and then carry out subsequent finishing. The surface treated with the presented material becomes stronger.
Finishing fits tightly to theprepared base. At the same time, the layers do not crack, they do not crumble. The finishing material will stay on the surface firmly. Further repairs will not be necessary for many more years. It is for this reason that the primer presented today is universally applied. It is produced by leading companies supplying high-quality construction materials to the market.
Today, the presented variety of primers produces many different brands. They are slightly different technical characteristics. Concrete contact Knauf, "Ceresite", "Starateli" and other manufacturers are made on the basis of acrylic. This material enhances the adhesion of the surface. In other words, the finish fits better with the base.
Cement, sand and other fillers are added to the acrylic base. It is these components that give the primer the appropriate qualities.
Priming can be treated as porous, andsmooth surfaces. It is designed for concrete, metal, ceramic, wooden, plastic, gipsokartonovyh surfaces. After their processing, it is possible to apply various plasters. Finishing can be made on a cement, lime, gypsum basis, as well as alabaster. Even on surfaces that do not absorb moisture at all, such plaster will hold firmly, do not exfoliate.
Certain properties are different "Concrete contact". Technical characteristics of "Ceresite" Knauf and other manufacturers may differ slightly. However, all of them are able to turn a smooth surface into a rough surface.
Время высыхания грунтовки составляет 3 часа.In some cases, the surface will be ready for further processing after 2 hours. Primer has a high index of moisture resistance. A film forms on the surface. It does not let moisture pass. Therefore, when using "Concrete contact" when finishing the floor, you can not use waterproofing.
The service life of the surface that has been impregnatedprimer is 80 years. Consumption is from 0.2 to 0.4 kg / m². "Concrete contact" has a pronounced color. After treatment on the surface, you can see if it is completely processed. When the product is absorbed, the omissions will be clearly visible. In this case, the substrate is ground again.
Considering technical characteristics of the ground "Concrete contact" we should say a few words about the consumption of the mixture.It depends on several parameters. For ease of use, pack primers in buckets of 5-10 liters. There are also containers of 30 and 40 liters. In closed form, "Concrete contact" is stored for 12 months.
The consumption of the mixture depends on the porosity of the substrate.The more the surface absorbs the primer, the more it will be required. More mixture will be required for surfaces made of brick, cellular concrete and other similar building materials. In this case, the consumption is 0.3-0.5 kg / m². Less money will be required if applied to a smooth surface. For ceramic tiles, metal, glass, the average consumption is 0.15-0.2 kg / m².
The amount of the product is also affected by the sizea fraction of the sand that is added to the acrylic base. The thinner the particle, the lower the flow rate, the application procedure will be characterized. A thick layer of the product is obtained by brushing the surface. If the primer is applied from the spray gun, the layer will be thin. The expense in this case is reduced.
Technical characteristics of the primer "Betonokontakt" talk about the mass of benefits of this tool. It is possible to apply the composition practically on any basis. It is applied even to the old lining.
Primer treatment is simple. Rapid drying of the layer allows you to quickly continue the subsequent repairs. After treatment, mold and fungus do not appear on the surface.
"Concrete contact" is an environmentally friendly material. It can be used inside any premises, even in the bedroom and the children's room.
Technical characteristics of "Concrete contact" позволяют применять его в разных областях repair work. The composition can be applied in the arrangement of rough screed floors or floors. Also, the primer is applied to the walls. After that they can be plastered, wallpaper wallpaper. On the ceiling, the agent is used before whitewashing.
The primer penetrates deeply into the material.The present tool is used for internal works. Repair work can be carried out at a temperature of 5 to 35 ºС. Also, the room should have a normal air humidity. Do not use the product at temperatures below 0 ° C.
After drying, the primer layer performsthe functions assigned to it under certain conditions. The ambient temperature should not fall below -40 ºС and rise above +50 ºС. Thanks to the use of special additives, the product withstands several cycles of freezing.
Each manufacturer assigns its products to certain technical characteristics. «Concrete contact» «Ceresite ST 19», "Knauf", "Starateli" differ in a number of indicators. These are the most popular primers in our country.
The products of Knauf containquartz sand. It is sold in a container of 5 kg. The presented primer is treated with concrete surfaces inside and outside the room. The cost of the submitted "Betonkontakt" is 600-800 rubles.
The company "Ceresit" also producesthe kind of primer presented. It is sold in a capacity of 15 kg. The price of this tool is about 1200 rubles. The presented composition is practically not inferior in quality to the previous variety of "Concretecontact".
One of the best compositions of domesticproduction is primer "Starateli". It is sold in packing 20 kg. The cost of the presented product is about 1400 rubles. The quality of this primer is not inferior to foreign analogues.
Having considered technical characteristics of "Betonocontact", it is necessary to understand the features of its application to the surface. First, the base must be properly prepared. The surface should be cleaned of dust and dirt.
After preparation, you can start creating a layerprimers. This work is carried out with a brush, roller or spray. It is necessary to follow that "Concrete contact" lay on the surface with a uniform layer. Then the agent should dry well. Features of the use of the product must be specified in the manufacturer's instructions.
After 3 hours, you need to check whether thesurface. If the primer is ready for further work, plaster is applied to it. You can also paste wallpaper, apply a coat of paint. If the substrate treated with Betonkontakt remains in its original state for more than 2 days, the procedure should be repeated.
Experts recommend buying a primeronly in specialized stores. Before applying the drug, you need to assess its consistency. The mixture should not be lumps. Knowing the technology of primer application, even a non-professional installer can perform the job well. In some cases (when the treatment area is large) it is recommended to use the services of professional installers.
Having considered the features «Concrete contact», technical characteristics primer, you can choose the right composition and apply it when carrying out repairs
