Glass Tile / September 12, 2018 / FifineAsselin
Consumers need to consider that many mesh backed material use poor quality glue to bond the tile to the mesh. When the mesh side is installed to the surface the mesh acts as a barrier between the tile and substrate. If the glue subsequently breaks down or the bond fails the tile can then easily loosen and fall out because little of the tile surface is actually bonded to the substrate. This failure can begin almost immediately or can take up to a few years after all installation warranties have expired. With Chinese produced glass tile my experience has shown the glue used to bond the tile to the mesh is lower in quality than the glue used in higher quality products produced in Europe or quality US manufacturers.
The most important step in putting glass tile in a swimming pool is choosing the right installation materials. To reiterate the high rate of expansion and contraction of glass caused by temperature changes is the leading cause of cracks and damage to installed tiles. In order to compensate for this special thin-set adhesives and additives have been developed that expand and contract with the glass. The leading manufacturer of glass-specific tile adhesive systems is MAPEI and their Adesilex P10 thin-set and Keraply additive can be combined into an installation system that is specifically designed for applications where the glass tiles are completely submerged.
The reason so much more grout is removed than when grouting conventional tile is because light refracts better through the glass tile when the sides of the tiles are exposed to the light. Work 3x3 spaces for about ½ hour or until the grout begins to dry then sponge off the grout. Bring several buckets of clean water and a sponge to the work area before you begin. Soak up some water into the sponge and gently wipe away the excess grout that is adhered to the tile. Smooth the grout lines with the sponge using one continuous swipe. Flip the sponge over and swipe more grout from the tiles until it becomes full of grout. Rinse the sponge in a clean bucket of water and repeat.
