Glass Tile / January 11, 2019 / Astrid Auclair
In situations where glass tile is exposed to extreme temperature differences an elasticizing polymer is added to the mix allowing the grout to stretch and flex preventing breaks from occurring in the delicate glass tiles. Using a grout float scoop a manageable amount of grout onto the float. Start at the farthest or highest spot away from you and spread the grout in between the tiles diagonally across the pattern. Dont worry about getting grout all over the tiles. The grout must be firmly pressed into the grout lines with the grout float covering all spaces and voids. Once a 3x3 section of grout has been applied to the tile use the small rubber edge of the grout float to remove about a third of the grout from between the tiles.
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.
What that means is glass expands and contracts at a greater rate than other materials someone might use in their pool e.g. ceramic or stone. Since the tile is adhered to the bottom of the pool while its expanding and contracting it can easily crack and break if the cement its laid into doesnt stretch with it. Therefore the question often heard from customers is "How do I install glass tile in my pool without having to repair the broken tiles year after year?" The answer has not always been an easy one. However with advances in technology and contractors growing experience installing glass tile we are now able to provide customers with the right recommendations so that their pool installation experiences minimal problems.
