In a silicone rubber composition of the condensation curing type comprising a diorganopolysiloxane having at least two silicon-attached hydroxyl or hydrolyzable radicals as a base polymer, and a silane having at least two hydrolyzable radicals or a partial hydrolytic condensate thereof, at least 2 mol % of the entire substituent radicals attached to silicon atoms in the diorganopolysiloxane are monovalent hydrocarbon radicals having at least two carbon atoms. The cured composition has excellent non-staining and sealing properties, and when applied as a coating, filled into joints, or used as a solid gasket, it does not cause staining of the building, joints, or the area around joints.
