🛠️ INSTALLATION REQUIREMENTS
⚠️ CRITICAL WARNING: SUBMERGED WATERPROOFING & MORTAR SELECTION
-
Pool-Grade Polymer-Modified Thinset: Always set porcelain pool tiles using an ANSI A118.15-compliant polymer-modified thinset mortar specified for submerged applications (such as LATICRETE® 254 Platinum or MAPEI® Kerabond T / Keralastic System).
-
100% Mortar Coverage: Back-butter mesh sheets as needed to ensure complete thinset contact behind all porcelain chips, eliminating hollow air pockets beneath water pressure.
Professional Installation Recommendations
-
Recommended Grout: Pair with a high-performance waterproof pool grout (such as LATICRETE® Spectralock® PRO Premium Epoxy Grout) in "Silver Shadow" or "Warm Gray" for a seamless tone-on-tone field, or "Dark Charcoal" for strong geometric contrast.
-
Grout Joint Width: Pre-spaced on the flexible mesh backing for uniform joint alignment throughout.
-
Cure Time: Allow a full cure time of 14 to 21 days before filling pools or spas with water.
💡 PRO CARE & MAINTENANCE TIPS
1. Routine Waterline Cleaning: Clean regularly using a soft sponge or soft brush and a pH-neutral pool tile cleaner to remove mineral deposits and body oils.
2. Maintain Water Chemistry: Keep pool pH (7.2–7.6) and calcium hardness balanced to prevent scale buildup along the glossy glaze.
3. Zero Sealing Required: Non-porous glazed porcelain requires no topical sealers, waxes, or protective coatings over its lifetime.
💬 FREQUENTLY ASKED QUESTIONS
Q: Is Fujiwa RIO-903 Oyster Gray safe for freeze-thaw winter climates?
A: Yes! Fujiwa porcelain tiles are high-fired with less than 0.5% water absorption, making them completely frost-proof and suitable for submerged outdoor applications in freeze-thaw climates.
Q: How does RIO-903 Oyster Gray compare to other tiles in the Rio Series?
A: While RIO-901 Persian Blue features cobalt/sapphire blues and RIO-902 Emerald Pearl offers deep gemstone greens, RIO-903 Oyster Gray is the neutral option, featuring a subtle blend of gray, greige, and misty slate.
Q: How many sheets should I order for a pool waterline?
A: Calculate your pool perimeter in linear feet. Since each sheet is 12 inches (1 foot) wide, multiply your waterline height fraction (e.g., 0.5 ft for a 6-inch row) by the perimeter, divide by 1.0 sq. ft. per sheet, and add 10% to 15% extra for waste and edge trimming.
