An adhesive for laying coverings on substrates consists of a mixture of a powder component (A) of a) a mixture of Portland cement, alumina cement and calcium sulfate, b) ferromagnetic iron powder, c) surface-modified silicates, d) hydroxycarboxylic acids, e) surfactants, defoamers and Extruders and a liquid component (B) to be added to this powder mixture before the use of the adhesive in the form of a synthetic resin dispersion based on the copolymers vinyl acetate / higher vinyl ester / ethylene and / or acrylic acid ester / styrene / acrylonitrile and / or butyl acetate / styrene with etherified polysaccharides and / or carboxyl groups Butadiene / styrene copolymers and / or vinyl acetate / ethylene / vinyl ester of "versatic acid". Instead of the liquid component to be kept separate, the adhesive may also contain a redispersible plastic powder based on the cemental-stable copolymers vinyl acetate / higher vinyl ester / ethylene and / or vinyl acetate / ethylene / acrylic ester and / or acrylic ester / styrene / acrylonitrile and be mixed with water. The invention further relates to the use of the adhesives and a method for laying coverings on substrates with their help. |
