Abstract

Compositions for coating roofs, facades, floors or vertical facings including at least one acrylic polymer and at least one polyurethane polymer and at least one ethylene vinyl acetate emulsion. The compositions combine the advantages of the excellent features of polyurethane compositions with the reduced cost of acrylic compositions in such a manner that a balance between both characteristics is shown. Methods for covering a roof, facade, floor or vertical facing with these compositions and the use thereof as a coating for roofs, facades, floors or vertical facings.
