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.
A coating system of high tensile strength and resilience for use as a coating for roofs, swimming pools and the like comprising an underlayer of asphalt material, an intermediate layer of woven fiber glass fabric, a first overlayer of coating material bonded to said underlayer and intermediate layer with said intermediate fiber glass fabric layer embedded between said underlayer and said first overlayer, and a second overlayer of said coating material bonded to said first overlayer, said woven fiber glass fabric including strands of bulked yarn in a relatively loose weave, and said coating material comprising an acrylic resin emulsion.
