Glass Tile / January 22, 2019 / Odette Pinneau
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.
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.
