The present invention relates to a process for the coating and water-repellent impregnation of mineral building materials, in which an architectural coating composition containing from 1 to 30 % by weight of C-C-alkyl-C-C-alkoxysilane as impregnating agent is applied to the building material. The principal architectural coating compositions are paints and plasters.

Self-priming architectural coatings

The invention relates to a stable aqueous cream consisting of the following components: (A), which is selected from (A1) C -C -alkyl-C -C -alkoxysilanes and (A2) organopolysiloxane containing alkoxy groups; (C) an emulsifier; and (D) an organic solvent. The stable aqueous cream is suitable for the hydrophobic impregnation or priming of mineral building materials.

Process for the water-repellent impregnation of plaster

Plaster is rendered water-repellent by impregnation with organosiloxanes containing Si-bonded hydrogen atoms and with alkali metal silicate. In particular, the water-repellent action is improved in the case of shaped plaster articles treated at high drying temperatures.
