Abstract
A process for rendering masonry water-repellent which comprises treating masonry which is alkaline, with a highly dispersed water-diluted impregnating composition which comprises (A1) an organoalkoxysilane and/or (A2) an organosiloxane containing alkoxy groups and (B) a water-soluble organic or inorganic acid salt of an organopolysiloxane, which in addition to other organosiloxane units contains siloxane units which carry monovalent SiC-bonded radicals containing basic nitrogen in amounts of at least 0.5% by weight, based on the weight of the organopolysiloxane. The treated masonry is particularly resistant to rising dampness.
