Glass Tile / January 3, 2019 / Morgana Faubert
The reason for doing this is when installing the glass tiles you do not want to see the trowel marks through the glass tiles. Another key to think about when installing the translucent tile is to make sure the surface behind the tile is white. If you have a painted kitchen and the walls are currently a dark or strong color that color could appear through the glass tile. If installing the translucent tile make sure the surface is painted white first and make sure the use of white thin set as well. The second type of glass is where the glass itself is a crystal type glass with the color backed on the back. Most 4mm or 8mm crystal type glass is clear and then the color of the tile is applied on the back of the tile giving it the color.
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.
