PURPOSE:To titled adhesive suitable for bonding a mortar structure to a plaster board or the plasterboard to wall paper, having improved bond strength, con sisting of a hydroxyl-containing liquid diene polymer, a polyisocyanate com pound, and mortar. CONSTITUTION:(A) A hydroxyl group-containing diene polymer (e.g., butadiene homopolymer, etc., containing preferably 0.3-0.5meq/g hydroxyl group content) is blended with (B) a polyisocyanate compound (most preferably tolyene diiso cyanate, etc.), (C) mortar, and, if necessary, a reinforcing agent (most preferably aniline polyol compound), etc., and kneaded, to give the aimed adhesive for building materials such as preferably mortar structure, plasterboard or wall paper. A molar ratio of OH in the component A to NCO in the component B is preferably 0.5-1.2. EFFECT:Time of drying process is shortened and propagation of mold is pre vented.
