ABSTRACT:
A textured coating and method of applying same. The coating comprises a high-solids polyamide epoxy having a resin and a hardener, and the epoxy is mixed with a texture aggregate filler being selected from the group consisting of perlite, glass microballoons, glass bubbles, phenolic microballoons, Q cel microspheres, and extendospheres, with the filler preferably being expanded perlite of a size such that about 20% maximum by weight is retained on a U.S. Std. Sieve No. 50 and such that about 65% maximum by weight is retained on a U.S. Std. Sieve No. 100. The epoxy and the filler are mixed in about equal volume. The method has the steps of: combining the resin and hardener to create the epoxy, then waiting a sweat-in time for the epoxy, then adding and blending the filler to the epoxy then adding thinner to the blended filler and epoxy to create a mixture of sprayable viscosity; then gently blending the mixture; and then spraying said blended filler and epoxy onto a surface using a spray gun, and then allowing the epoxy coating to cure.
