    摘要: The invention relates to a method for producing coated mineral shaped bodies by applying an aqueous coating agent containing a polymer dispersion serving as a bonding agent and at least one aqueous styrene maleic anhydride copolymer solution. The shaped body is subsequently hardened and the coating agent is dried. The invention is characterized in that the at least one aqueous styrene maleic anhydride copolymer solution is added to the polymer dispersion after completion of the polymerization. The shaped bodies coated in such a manner exhibit an improved efflorescence behavior. The method is particularly suited for coating roofing tiles and fibrated concrete slabs.
