Glass Tile / January 19, 2019 / Fealty Allaire
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.
Often glass tiles are translucent in appearance and any imperfection in either the setting application or the thinset is magnified. Whichever tile is being installed the substrate must be perfectly smooth using the manufacturers suggested setting materials and following their instructions exactly as written. Any "waves or grooves" in setting material are noticeable which is another reason a consumer needs to hire a contractor trained in glass tile installation. Another major quality difference between glass tiles is in the quality of the glass used during production. Oceanside Glass is famous for using recycled bottles in its production and provides consumers with a guide of how much post-consumer recycled material are used in their production and can assist with LEED accreditation. Additionally their state-of-the-art equipment for precision processing in batching changing furnaces and cooling molten glass is revolutionary.
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.
