Claim:
A method of termite proofing a building structure, the building structure having a foundation located below an adjacent finished ground level and an external wall formed on the foundation and defining an exterior surface of the building structure, the exterior surface being defined at least in part by a cementitious material, said method comprising: applying a curable composition to the cementitious material throughout a lower region of the exterior surface extending from the foundation to a predetermined height above the finished ground level, such that said composition penetrates into and is retained within the cementitious material; allowing said composition to cure within the cementitious material throughout said lower region, wherein said composition cures within the cementitious material, thereby protecting the cementitious material against intrusion by termites; wherein said composition, when cured, hardens the cementitious material; wherein a majority of said composition penetrates into the cementitious material; and wherein a residual film of said composition initially remains on the exterior surface following application, said residual film breaking down under the action of ultraviolet radiation within a period of six months.
