PROBLEM TO BE SOLVED: To obtain a condensation curing coating composition improved in properties regarding room-temperature vulcanizable anti-fouling coating, especially preventive efficiency and effective life by compounding a specific composition and a specific polyorganosiloxane. SOLUTION: This composition is obtained by compounding (A) a room- temperature vulcanizable polyorganosiloxane composition of one-pack type or two-pack type, (B) not less than one kind of polyorganosiloxane, which is free from a silanol group and containing one or more of polyoxyalkylenealkyl having a terminal hydroxyl or alkoxyl group in an amount of about 10-60 wt.%, having a function for blooming the surface of hardened product of the component A in an amount effective for marine anti-fouling acceleration, and optionally (C) a reaction product of these components. The component A preferably contains a reactive silicone, a condensation catalyst, a crosslinking agent, optionally a filler for reinforcement and extender (non reinforcement), etc.
