How to Install Glass Tile Murals

SMOOTH glass tile for walls and TEXTURED for floors:

Glass tiles are not absorbent, like ceramic, thus different techniques are required to install glass tile. Testing performed by the Tile Council of America proved our textured glass tiles meet ANSI and ASTM standards for commercial wall and floor applications. Our glass tiles’ breaking strength surpasses floor standards by more than 700 percent. Both smooth and textured glass pass freeze-thaw testing, as well as resistance to chemical substances including household and commercial cleaning materials, swimming pool chemicals, hydrochloric acid solution and potassium hydroxide. The textured glass tile surface has a coefficient of friction that exceeds OSHA standards for non-slip safety.

To Install Glass Tile

Epoxy adhesives provide the best results. Suggested products are Mer-Krete (Pro Epoxy Mortar and Grout), Custom Building Products (EBM-LITE™ PREMIUM EPOXY BONDING MORTAR) and Laticrete (Latapoxy 300).  Follow the manufacturer’s recommendation for applying.

To insure vivid, uniform color for the image, use WHITE epoxy adhesive. Apply with a notched trowel per manufacturers’ recommendations. Apply a thin coat of the same adhesive to the back of the tile (‘back-buttering’), then place tile and be sure to achieve full contact in the adhesive bed (especially for floor tiles, see why). Use spacers between the tiles for uniform grout joints. Butting the tiles together without grout runs the risk of damaging the tiles if the substrate flexes due to temperature or humidity fluctuations or any other cause for movement.

Note: Handle glass tiles carefully to avoid scratching the imaged side – the white coating (which covers the image on the backside) can be scratched by metal tools and by other tiles.

Grouting Glass Tiles

After the mural is installed and adhesive has cured to the manufacturer’s specifications, use a grout specifically formulated for glass tile (e.g., Polyblend® Non-Sanded Grout  by Custom Building Products or Mapei’s Kerapoxy Stain-Free Grout). Epoxy grouts are waterproof and offer excellent stain resistance. Epoxy grouts are recommended for graffiti resistance and stain resistance.

After installation: clean thoroughly with a soft cloth or sponge, using glass cleaner, mineral spirits, or non-abrasive citrus cleaner to remove fingerprints and other soils.

Custom printed glass tiles require simple cleaning with products designed for glass. Use a soft, lint free cloth for cleaning. Never use abrasive cleaners or pads on glass tiles.
