Elastomeric waterproofing coatings are formulated and designed as ultra-performance, seamless, permanent, elastic waterproofing membranes for roofs. With optimised solar reflective properties, these types of coatings are also known as elastomeric cool roof coatings [1-9]. Cool roof coatings are often formulated with binders that give the coatings elastomeric properties. The coatings should have the ability to move with the substrate over quite extreme temperature cycles without cracking or debonding from the substrate. The coating should also endure weather conditions over many years and stay free of dirt and pollution. These coating formulations are often based on high-quality acrylic or polyurethane binders, ...
