PROBLEM TO BE SOLVED: To provide an ordinary-temperature-curing coating composition which resists to sagging and forms a coating film excellent in initial driability, hot-water resistance, weathering resistance, stain resistance, cracking resistance, etc. SOLUTION: The coating composition comprises (A) a resin composition containing 100 pts.mass (I) liquid condensate of a partial hydrolyzate of an organosilane represented by formula (1): R<SP>1</SP><SB>n</SB>Si(OR<SP>2</SP>)<SB>4-n</SB>[wherein R<SP>1</SP>is a 1-8C organic group; R<SP>2</SP>is a 1-5C alkyl group; and n is 1 or 2], 3-50 pts.mass (II) solid condensate of a hydrolyzate of the organosilane of the formula (1), the solid condensate being soluble in the liquid condensate, 2-30 pts.mass (III) epoxy- containing alkoxysilane compound, 0-30 pts.mass (IV) organosilane compound represented by formula (1), and 0-100 pts.mass (V) silyl-containing vinyl resin having hydrolyzable silyl groups or OH-bonded-Si-containing silyl groups and (B) amino-containing dimethylpolysiloxane compound.
