Glass Tile / September 9, 2018 / FifineAsselin
Consumers need to consider that many mesh backed material use poor quality glue to bond the tile to the mesh. When the mesh side is installed to the surface the mesh acts as a barrier between the tile and substrate. If the glue subsequently breaks down or the bond fails the tile can then easily loosen and fall out because little of the tile surface is actually bonded to the substrate. This failure can begin almost immediately or can take up to a few years after all installation warranties have expired. With Chinese produced glass tile my experience has shown the glue used to bond the tile to the mesh is lower in quality than the glue used in higher quality products produced in Europe or quality US manufacturers.
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 first type of tile is a translucent glass. A translucent glass is a type of tile that you could actually hold up and see right through it. The most common types of glass that is translucent is a recycled glass or an oval penny round or brick type of tile. Majority of translucent glass tiles are paper faced. The reason that most of these are paper faced is because the mesh backing can be seen through the glass tile. When installing this type of glass tile you want to use a small notch trowel when spreading your mastic on the installation surface. After spreading the mastic you will want to flatten down or knock down the trowel marks.
