Application Surfaces
Structural primer designed for leveling and increasing the adhesion of low adhesion, high density smooth substrates. It is used as a primer before plastering with lime-cement plaster or lime plaster and lime, for plasterboard coating prior to laying tiles and laying new tiles on an already existing tile layer. BK-Beton Contact is recommended especially for smooth concrete surfaces as well as prefabricated reinforced concrete elements. It is classified as an organic product, is not harmful to human health and the environment and is free of organic solvents.
Application
The surface to be applied must be solid, clean and dry, free of greasy stains and other similar surfaces. Suitable surfaces are all smooth cement surfaces, precast concrete, gypsum board (before tiling) and the like. All old, poorly clinging layers must be removed. Remove the appropriate material before applying the primer. When laying new tiles on old ones, it is necessary to clean and wash the existing tiles, as well as make them with better adhesion, it is recommended to be further treated for a coarse surface , then coat with BK-Beton Contact primer. If the painted surfaces are covered with oil paints, lacquers and the like, it is necessary to completely remove existing paint layers.
Dilution
Before use, mix thoroughly. The primer is applied undiluted, with a brush or a long-haul roller in one layer. If necessary, it may be diluted with small amounts of water (max. 2%).
