Water repellent for masonry

A composition for rendering masonry water repellent, consisting of:

• (a) an organopolysiloxane resin selected from the group consisting of resins containing R.sub.3 SiO.sub.0.5 units and SiO.sub.2 units, the ratio of R.sub.3 SiO.sub.0.5 units to SiO.sub.2 units ranging from about 0.2 to about 0.9:1 and resins containing R.sub.3 SiO.sub.0.5 units, R.sub.2 SiO units, and SiO.sub.2 units, the ratio of R.sub.3 SiO.sub.0.5 units to SiO.sub.2 units ranging from about 0.2 to about 0.9:1 and the ratio of R.sub.2 SiO units to SiO.sub.2 units being up to about 0.1:1;
• where each R is an independently selected substituted or unsubstituted alkyl radical, aryl radical, alkaryl radical, aralkyl radical, cycloalkyl radical or alkenyl radical;
• (b) an alkylalkoxypolysiloxane resin;
• and
• (c) an effective amount of solvent.
