Abstract
Method for bonding a room temperature vulcanisable silicone rubber to a porous substrate of masonry or wood. The method involves applying to the porous substrate a primer composition comprising a cyclised rubber resin, an organic solvent and a film-forming polyester resin in a proportion of from 0 to 40% by weight based on the weight of cyclised rubber resin. The primed surface is dried and a room temperature vulcanisable silicone rubber composition of specified type then applied.
