CEKOL GS-83 KONTAKT is a preparation for priming smooth surfaces, ceilings and prefabricated elements made of smoothly decked elements in concrete and reinforced concrete. The CEKOL GS-83 KONTAKT preparation is intended to improve the adhesion of plaster to difficult substrates. It can be used indoors and outdoors.

The preparation is non-toxic and non-flammable. Strengthens substrates, increases adhesion to plaster, putty and adhesive mortars. When plastering, CEKOL GS-83 KONTAKT improves the uniformity of mortar application, improves their adhesion and facilitates application. After drying, a rough coating is formed on the surface, resistant to water and alkaline agent, which does not inhibit the exchange of water vapor and gas with the environment. Drying time: from several to 24 hours (depending on temperature and humidity).
