Abstract

The invention describes a method of coating a concrete molding which comprises a) the application of at least one plastic, cement-bound mineral composition to an uncoated mineral molding wherein said plastic composition comprises at least one aqueous polymer dispersion and b) bringing about the setting of the plastic composition, wherein the aqueous polymer dispersion comprises: at least one polymer P in the form of dispersed polymer particles with a glass transition temperature of from −20 to +80° C., the polymer containing not more than 2% by weight of copolymerized monoethylenically unsaturated monomers having an acid group.
