A slump-resistant, curable polymer concrete composition, suitable for coating onto a concrete surface or an asphalt surface to resurface same, comprising (a) 5 to 95 weight percent of an aggregate at least 20 percent of which has a minimum particle dimension of 1/16 inch or greater, (b) 5 to 95 weight percent of a curable polymer composition containing an ethylenically unsaturated polymer containing carbon, hydrogen and oxygen in the molecule and carbon-bonded carboxyl groups or carbon-bonded hydroxyl groups or both in the molecule, (c) an effective amount of a curing catalyst effective to initiate the curing of the polymer, and (d) at least one reactive, time-delay thickener comprising (1) a Group IIA metal oxide or hydroxide in the amount of 0.1 to 20 equivalents per carbon-bonded carboxyl group of the polymer, the Group IIA metal oxide or hydroxide being reactive with the carboxyl groups of the polymer to thicken said polymer concrete composition and/or (2) a polyisocyanate in the amount of 0.1 to 10 equivalents per carbon-bonded hydroxyl group of the polymer, the polyisocyanate being reactive with the hydroxyl groups of the polymer to thicken the polymer concrete composition. Also, a method of repairing or resurfacing a concrete surface or an asphalt surface comprising the steps of: (1) prime-coating the surface with a primer composition comprising a curable polymer composition containing an ethylenically unsaturated polymer containing carbon, hydrogen and oxygen in the molecule and carbon-bonded carboxyl groups or carbon-bonded hydroxyl groups or both in the molecule, and an effective amount of a curing catalyst effective to initiate the curing of the polymer, (2) coating the prime-coated surface with the above-identified polymer concrete composition and (3) shaping the polymer concrete composition on the prime-coated surface. In addition, concrete structures having adhered to the surface thereof a polymer concrete composition as described above in cured condition.
