Glass Tile / September 14, 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.
In addition there are two other eminent glass surface treatments for these tiles: slumping and etching. Smalti tile is type of tile which is an opaque glass. It has been in use from ancient times. "Smalti" is an Italian word and refers to a glass paste. Smalti is made by mixing molten glass with metal oxides for color. Translucent Smalti is a popular variant of smalti glass tile. It looks like stained glass with uniform colors. Byzantine Glass is another smalti variant made from thinner slabs of glass. Metallic Smalti is a swirl of a copper-bearing mineral added into the molten glass before it is pressed. Gold Smalti are made by applying a gold leaf and a thin layer of blown glass. Fused Tile is manufactured using the fusion method. In this type a flat glass is cut into tiles shapes and then fired in a furnace. The clear glass will show the tile until treated with a 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.
