Glass Tile / January 24, 2019 / Genevieve Brunelle
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.
According to Wes Wayland of Bisazza USA "It gives a client the ability to clad curved surfaces both concave and convex and to form clean inside and outside corners with more ease and a finished look. This also gives them the ability to create mosaics on furniture walls ceilings pools even cladding of entire buildings with unique designs". Glass tile isnt JUST for the bathroom anymore. Bisazza wants consumers and designers to think outside the box and are offering prefabricated mosaic patterns and designs intended to cover large vertical surfaces as wallpaper would and that are perfectly suited for the bedroom - living room - board room - foyer - etc.
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.
