Product Overview

Fujiwa Sekis Series: French Grey 6" x 6" Matte Porcelain Tile is a premium architectural pool and outdoor tile engineered specifically for submerged aquatic environments, waterline installations, and exterior hardscapes. Designed to capture the subtle texture and organic look of natural stone, the French Greycolorway features a sophisticated, multi-tonal palette of soft slate gray, subtle charcoal striations, and cool stone undertones in a satin-matte finish.

Manufactured by Fujiwa Tiles, a recognized leader in aquatic ceramic and porcelain solutions, this 6" x 6" square tile features an vitrified fine porcelain body with near-zero water absorption (< 0.5%). Built to withstand harsh chemical exposures, severe freeze-thaw winter cycles, and continuous UV rays, it offers an enduring, non-reflective alternative to traditional glossy pool tiles.

Technical Specifications

Recommended Applications

• Swimming Pools & Spas: Pool waterline tile runs, raised spa spillways, submerged bench accents, and step marker safety 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 6x6 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: Natural Slate, French Limestone, Organic Modernism, and Luxury Resort Sanctuaries.

• Finish Advantage: The textured matte finish reduces harsh sun glare off the waterline while providing an organic stone texture that complements natural coping materials.

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

Frequently Asked Questions

Is Fujiwa Sekis French Grey 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.

What are the design benefits of a matte finish pool tile over glossy tile?

A matte finish provides a subtle, stone-like aesthetic that softens sunlight reflection along the waterline. It creates a seamless transition with natural stone coping and plaster finishes, offering a modern, organic look rather than a reflective glass or glossy finish.

Can this 6" x 6" 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.

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.
