Product Overview

Fujiwa Pilos Series: Spring Glazed Porcelain Random Block Mosaic Tile is a high-performance architectural mosaic tile engineered specifically for submerged aquatic environments, pool waterlines, and outdoor living spaces. Drawing inspiration from natural stone blocks and spring water reflections, the Springcolorway features a rich multi-tonal glaze blend of vibrant aquatic blues, soft seafoam green undertones, and warm mineral accents arranged in a dynamic random block layout.

Manufactured by Fujiwa Tiles, a recognized leader in pool and outdoor ceramics, this frost-proof glazed porcelain mosaic features an impervious body with near-zero water absorption. It is designed to withstand severe freeze-thaw cycles, prolonged UV exposure, and pool chemical treatments without fading, cracking, or crazing over time. Pre-assembled on flexible mesh-backed sheets, it allows for seamless installation along pool waterlines, contoured spa walls, and shower surfaces.

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 mosaic chip 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: Fresh Mountain Springs, Coastal Lagoons, and Resort-Style Aquatic Architecture.

• Glaze Characteristics: Multi-depth random block layout with light-refracting glaze variations that create dynamic movement under moving water.

• Complementary Finishes: Pairs exceptionally well with precast stone pool coping, white quartz plaster finishes, dark blue or jade pebble pool linings, and natural stone pavers.

Frequently Asked Questions

Is Fujiwa Pilos Spring 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?

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.

What is the advantage of a random block pattern over standard square pool tile?

The random block format breaks up rigid grid lines, offering a more organic, artisanal appearance along the waterline. It also helps disguise curved pool walls and steps smoothly without needing excessive tile cuts.

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.
