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 abrasive pads on glass tiles.
