Abstract: Surprisingly aqueous preparations containing a copolymer P as completely or largely cross linked constituent comprising methacrylic acid alkyl esters, in which the bulk of methyl methacrylate monomer varies give coatings of gloss with increased stability over time. The coatings show good adhesions to mineral substrates and guarantee good protection against efflorescence. The use of an aqueous film forming preparation, for coating a mineral molded body, containing at least one copolymer P as film forming component dispersed in the preparation and ethylenically unsaturated monomers M is new. The monomer M comprises (wt. %): (i) 70-99 of at least one methacrylic acid ester with a 1-10C alkanol and (ii) 0.1-30 of at least one of different ethylenically unsaturated monomers, in which at least 50 wt. % of monomer M comprises methacrylic acid methyl ester, and at most 1 wt. % of monomer M contains two or more ethylenically unsaturated double bonds. Independent claims are included for: (1) A process for coating a mineral molded body with at least one aqueous film forming preparation; (2) a mineral molded body.
