This original piece is a wedding cake style fountain that has been constructed of concrete formed sections. Each section is bolted into place and then Pond Shield Gray was used in conjunction with fiberglass tape to seal the completed unit. After all was cured, the epoxy was abraded and then black glass tiles were set in place. Polyurethane or a very sticky acrylic thinset can be used for setting the tile. This way the waterproof barrier was installed first in order to preserve the natural beauty of the tile itself.
