    摘要： A roofing repair system including a multi-part primer and a water-activated overcoat composition. The multi-part primer includes a first part including a hydroxyl-functional (meth)acrylic (co)polymer, and a second part including a mixture of a hydrophilic polyfunctional aliphatic polyisocyanate and a hydrophobic polyfunctional aliphatic polyisocyanate, wherein a molar ratio of hydroxyl functionality in the first part to isocyanate functionality in the second part is less than 1. The water-activated overcoat composition includes at least one compound selected from polyketimines having amino groups attached to secondary carbon atoms, polyenamines, and oxazolidines. In some exemplary embodiments, the volume ratio of the multi-part primer to the water-activated composition is from 5:1 to 7:1. In certain exemplary embodiments, the multi-part primer is substantially free of organic solvents. A method of using the roofing repair system to repair the weathered surface of an elastomeric roofing membrane is also described.
