PRIMING PREPARATION KONTAKT • CEKOL GS-83 Kontakt is a product used for priming smooth surfaces, ceilings and prefabricated elements made from smoothly planked concrete or reinforced concrete elements. • It reinforces the substrate, improves the bonding uniformity and increases the adhesion of plasters, putties and mortars to difficult surfaces. • It can be used inside and outside buildings. • After drying, the product creates a transparent rough coating resistant to water and alkaline agents. The coating does not inhibit the exchange of water vapour and gases with the environment. • It is non-toxic and non-flammable.
