Abstract: A coating system of high tensile strength and resilience for use as a coating for roofs, swimming pools or the like having an underlayer of coating material, an intermediate layer of woven fiber glass fabric that includes strands of bulked yarn in a relatively loose weave, and an overlayer of coating material, with the fiber glass fabric being embedded in the coating system between the underlayer and overlayer. Alternatively the underlayer may be of asphalt material and the overlayer may be a first overlayer bonded to the underlayer with the intermediate layer embedded therebetween and a second overlayer bonded to the first overlayer. The coating material contains water, a high solids thermoplastic acrylic emulsion, calcium carbonate, titanium dioxide, sodium salt of polymeric carboxylic acid, a wetting, emulsifying and stabilizing agent and defoamers, with zinc oxide being used if desired for mildew resistance.
