ABSTRACT:
The present invention relates to a process for coating mineral moldings with film-forming aqueous formulations in which in succession at least one 1st formulation comprising at least one copolymer P1 as binder and at least one inorganic pigment is applied to the mineral molding and, if desired, is dried and then at least one 2nd formulation comprising at least one copolymer P2 as binder and, if desired, inorganic pigment is applied, the copolymers P1 and P2 each being composed of monomers A, B and, if desired, C, wherein identical monomers A and B are selected in each case for the copolymers P1 and P2 and the 1st. formulation has a pigment volume concentration which is greater by at least 10 than that of the 2nd formulation, and to a composition of said 1st and 2nd formulations and to the use of said 1st and 2nd formulations for coating mineral moldings.
