Glass Tile / January 6, 2019 / Astrid Hachee
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.
I am amazed at the number of tile contractors who claim to be experts in glass tile installations yet cannot even tell the right direction the tile should be installed! Some contractors will not admit they are unskilled and untrained at this specialty and install the tile upside down because they have never worked with "paper faced material". They later call to complain that tiles are falling out and have glass imperfections. So the first rule is to ensure the person who is installing your glass tile has attended a glass tile setting seminar such as those offered by Bisazza or Oceanside Glasstile or otherwise demonstrated glass tile installation competency.
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.
