The problems with epoxy repairs on exterior tile are significant. First, the coefficient of thermal expansion of the epoxy is much higher than that of the tile. Every day the sun hits that facade, the epoxy is working its way off the wall as it responds to the temperature rising. Second issue is moisture. Anytime you cover a significant area with epoxy, you'd better have moisture seriously under control - something that rarely happens, and that leads to moisture entrapment and delamination. Third- UV. Epoxies will not retain color or gloss in sunlight, even through glass, much less in direct exposures. Edison Coatings, Inc. Michael P.
