(Also see Delicate Glass Tile)
Glass tile is made from pouring melted glass into molds or fusing pieces of glass together with heat.
Some glass tiles have unique backings or coatings and require special types of setting materials. Always follow the glass-tile manufacturer’s written installation instructions.
For most installations of glass tile, MAPEI recommends Adesilex P10 Mosaic & Glass Tile. When installing glass tile in a pool or when installing glass tile over waterproofing membranes, such as MAPEI’s Mapelastic AquaDefense, use MAPEI’s Adesilex P10 Mosaic & Glass Tile mixed with MAPEI’s Keraply.
When grouting glass tile, use an unsanded grout such as MAPEI’s Keracolor U. If a sanded appearance is desired, a colored quartz (CQ) grout such as MAPEI Flexcolor CQ or MAPEI’s Kerapoxy CQ can sometimes be used successfully, but a test panel should be grouted and inspected for unacceptable scratching before grouting. Delicate glass tile should only be grouted with an unsanded grout, such as MAPEI’s Keracolor U. Adding MAPEI’s UltraCare Grout Maximizer to MAPEI’s Keracolor U will help to reduce the porosity of the grout and help to keep the grout clean.
