Product Overview

Fujiwa Rio Series: Oyster Gray Glazed Porcelain Tile is a premium architectural pool tile engineered specifically for submerged aquatic environments, waterline applications, and outdoor living spaces. Inspired by natural coastal stones and subtle sea-mist reflections, the Oyster Gray colorway features a sophisticated glaze blend of soft slate gray, pearl, charcoal undertones, and subtle metallic sheen that shifts gracefully under sunlight and water movement.

Manufactured by Fujiwa Tiles, a recognized leader in pool and outdoor ceramics, this frost-proof glazed porcelain tile features an impervious body with near-zero water absorption. It is built to endure severe freeze-thaw cycles, prolonged UV exposure, and pool chemical treatments without fading, cracking, or crazing over time.

Technical Specifications

Recommended Applications

• Swimming Pools & Spas: Pool waterline tile runs, raised spa spillways, submerged bench accents, and step marker highlights.

• Aquatic Architectural Features: Outdoor fountains, waterfall spillways, reflecting pools, and water walls.

• Exterior & Interior Surfaces: Patio wet bars, outdoor kitchen backsplashes, primary bathroom accents, and shower walls.

Installation & Handling Guidelines

⚠️ CRITICAL WARNING: AQUATIC & POOL MORTAR PROTOCOL

• Thinset Mortar Selection: Swimming pool and submerged tile installations require high-flexibility, polymer-modified thinset specified for submerged aquatic environments. Install using an ANSI A118.15-compliant latex-polymer modified mortar (such as MAPEI® Kerabond T / Keralastic System or LATICRETE® 254 Platinum).

• 100% Mortar Coverage: Achieving 100% mortar contact behind every tile is mandatory in submerged applications. Voids or air pockets behind tiles trapped underwater can cause moisture accumulation, efflorescence, and eventual tile pop-offs.

• Grout Selection: Use a high-performance, water-resistant grout specified for swimming pools, such as a high-density cementitious grout (ANSI A118.7) or 100% solid industrial epoxy grout (ANSI A118.3 like MAPEI® Kerapoxy or LATICRETE® SpectraLOCK® Pro Premium) for maximum stain and chemical resistance.

Professional Recommendations

• Waterline Curing Time: Allow thinset and grout to fully cure per manufacturer instructions (typically 14 to 21 days minimum) before filling the pool with water or adding pool chemicals.

• Movement Joints: Install expansion joints at all plane changes, pool corners, and coping transitions per TCNA EJ171 guidelines.

Care & Maintenance

• Routine Cleaning: Clean pool waterline scale and body oils using a non-abrasive pool tile cleaner or a soft brush with pH-neutral soap.

• Chemical Balance: Maintain proper water chemistry (pH, total alkalinity, and calcium hardness) to prevent calcium scale buildup or mineral deposits along the waterline.

• Zero Sealing Required: Non-porous glazed porcelain is completely impervious to water penetration and never requires sealers or topical coatings.

Design Profile

• Aesthetic Inspiration: Organic Modern Coastal, Soft Mineral Quartzite, and Contemporary Architectural Sanctuaries.

• Glaze Characteristics: Subtle multi-tonal gray glaze that provides a modern, neutral alternative to traditional blue pool tiles while enhancing water clarity.

• Complementary Finishes: Pairs exceptionally well with poured concrete or light travertine pool coping, French gray or white pebble pool linings, and natural teak or concrete pavers.

Frequently Asked Questions

Is Fujiwa Rio Oyster Gray suitable for saltwater swimming pools?

Yes! Fujiwa glazed porcelain tiles are fully impervious (< 0.5% water absorption) and chemical-resistant, making them completely safe for both traditional chlorine and saltwater pool systems.

Can this tile withstand freezing winter weather?

A: Absolutely. Fujiwa pool tiles are tested and certified frost-proof (ASTM C1026). They are engineered to endure severe freeze-thaw winter cycles without cracking, spalling, or debonding when installed with proper movement joints and ANSI A118.15 thinset.

How does Oyster Gray look in the water compared to blue tile?

Oyster Gray creates a sophisticated, modern water appearance. Instead of the intense electric blue produced by blue tile, Oyster Gray produces a clean, natural, crystal-clear blue-green water appearance reminiscent of luxury resort pools and natural mountain springs.

Why is pool-rated thinset required instead of standard tile mortar?

Submerged pool tiles are subject to constant water pressure, chemical exposure, and thermal expansion. Standard interior thinsets will break down underwater over time, leading to tile detachment. Always use an ANSI A118.15 or ANSI A118.3 aquatic-rated thinset and grout.
