SELF-ETCHING CEMENTITIOUS SUBSTRATE COATING COMPOSITION
Described is a method for producing a coating with an aqueous coating composition AC, the method comprising the following steps: a) applying the aqueous coating composition AC to a cementitious substrate; b) curing the applied aqueous coating composition AC; wherein the aqueous coating composition AC comprises at least one amino-functional vinyl copolymer VC and at least one epoxy silane ES and the coating composition has a pH of 3 - 6.5 and the weight ratio between amino-functional vinyl copolymer VC and epoxy silane ES (VC/ES) is from 1.0 - 9.5. Since the composition displays self-etching properties on concrete surfaces, cementitious substrates do not have to be mechanically or chemically pretreated before the composition is applied.
