Floor Tile Polished Glaze Frit is a pre-melted glassy granule blend designed for high-traffic surfaces, composed of 60% silica (base framework), 20% borosilicate (lowers melting point), and 8% zirconia (enhances wear resistance). | |||||||||

When fired at 1250°C for 12 minutes, it forms a glossy, scratch-resistant layer with a Mohs hardness rating of 6-7. The frit’s spherical granule shape (100-200μm diameter) reduces settling by 40% compared to traditional powder glazes, ensuring consistent coverage in automated production lines (e.g., 10,000+ tiles per day).
Superior Wear Resistance: Withstands 5,000+ revolutions in the Taber Abrasion Test (CS-10 wheel, 1kg load), making it suitable for high-traffic commercial spaces (shopping malls, airports)
High Gloss Finish: Reflectivity exceeding 85% (measured at 60° angle) enhances tile color vibrancy—deepens dark tones (e.g., charcoal) and brightens light tones (e.g., ivory) without color distortion
Slip Safety: Optional 15-20μm aluminum oxide texture additives achieve R10 anti-slip rating (per EN 14411 standard), reducing slip-and-fall risks in wet areas (bathrooms, entryways)
Cost Efficiency: Low water absorption (<0.5%) minimizes staining and mold growth, reducing maintenance costs by 30% annually compared to unglazed floor tiles; no need for waxing or sealants
Ideal for shopping malls, hotel lobbies, residential hallways, and office reception areas. Apply via automated spraying (nozzle diameter: 1.2mm, spray speed: 2-3m/min) for uniform coverage (dry film thickness: 0.5-0.6mm). Pair with porcelain floor tiles (water absorption <0.5%) for optimal durability in high-moisture areas (e.g., bathroom floors)—the glaze’s dense structure prevents water penetration. For large-scale projects, mix frit with deionized water (1:0.8 frit-to-water ratio) to ensure pumpability in production equipment.
Q: How to prevent pinholes in the polished surface?
A: Ensure thorough bisque firing at 1060°C for 15 minutes to burn off organic impurities (e.g., cellulose binders) in the tile body. Avoid over-firing the frit (>1270°C), as it causes excessive gas release and pinhole formation. If pinholes appear, sand the surface lightly (400-grit sandpaper) and reapply a thin glaze layer.
Q: Can it be used on existing floor tiles?
A: Only on unglazed tiles (e.g., quarry tiles) or tiles with completely removed old glaze. Sand the existing surface with 240-grit sandpaper to achieve a roughness of Ra 3.2μm, then clean with a degreaser (e.g., isopropyl alcohol) to remove oil. Apply 2 coats of glaze and refire at 1250°C—note: existing tiles must withstand high firing temperatures (avoid ceramic tiles with plastic backings).
Q: What’s the heat resistance limit?
A: Withstands continuous temperatures up to 300°C (e.g., hot pans placed briefly) without cracking or discoloration. Short-term exposure to 400°C (e.g., accidental candle contact) is tolerable, but prolonged exposure (>10 minutes) may cause slight gloss loss—restore with a polishing compound (ceramic-specific) and a soft buffer.
