This is the "Architectural Fortress" of the collection. While standard interior tiles focus on smoothness, the Cerdomus Ostuni Avorio Grip R11 is engineered for high-performance safety without sacrificing the rustic elegance of Italian stone. It is the premier choice for a "Seamless Indoor-Outdoor" or "Modern Mediterranean" aesthetic, prioritizing a high-friction surface that makes grand terraces, pool surrounds, and wet rooms feel secure and sophisticated.

PRODUCT TITLE

Ostuni Series: Avorio 16" x 24" Porcelain Tile (Grip R11 Finish) by Cerdomus

PRODUCT DESCRIPTION

Bridge the gap between your interior sanctuary and the great outdoors with the Ostuni Avorio Grip. Designed by the masters at Cerdomus in Italy, this tile is a tribute to the sun-drenched, tumbled limestone of Puglia. The "Avorio" (Ivory) colorway is a luminous, warm-cream base accented by subtle fossil-like textures and soft, weathered edges that evoke the passage of time.

The Grip R11 finish is the defining feature of this tile. It is a specialized, anti-slip surface treatment that provides maximum traction even when the tile is submerged or soaking wet. Despite its rugged R11 safety rating, the tile maintains a refined, tactile feel that is comfortable for bare feet. The 16" x 24" format offers a traditional, stone-block proportion that minimizes grout lines compared to smaller pavers, creating a continuous, expansive floor that can withstand the harshest elements.

KEY FEATURES

• High-Performance R11 Grip: Certified slip resistance, making it the "Safety Standard" for pool decks, outdoor stairs, and commercial entryways.

• Authentic Tumbled Aesthetic: Features the "Ostuni" signature weathered edges and stone-effect surface for a timeless, hand-carved look.

• Sun-Bleached Avorio Palette: A warm, neutral ivory that reflects sunlight, keeping outdoor surfaces cooler to the touch than darker stones.

• Full-Body Italian Porcelain: Engineered to be frost-proof, chemical-resistant, and impervious to water, ensuring the color never fades under UV exposure.

• Modular Versatility: The 16x24 size works perfectly as a standalone bond or as part of a multi-size "Versailles" pattern.

INSTALLATION REQUIREMENTS

⚠️ CRITICAL: For outdoor installations, the substrate is everything. You must use a High-Performance, Frost-Resistant Thin-set and ensure 100% mortar coverage to prevent water from trapped under tiles, which can lead to "popping" in freezing temperatures.

Manufacturer Recommendations:

• Recommended Grout: Use a High-Performance, Water-Repellent Grout in "Ivory," "Sand," or "Beige."These colors blend seamlessly with the Avorio edges.

• Joint Size: A minimum of 3 mm (approx. 1/8") is recommended to accommodate the slightly weathered, tumbled edge of the Ostuni series.

• Drainage: Always ensure the subfloor has a minimum 2% slope (1/4" per foot) away from the house to prevent water pooling on the Grip surface.

FREQUENTLY ASKED QUESTIONS

• Is it hard to clean? Because of the Grip texture, a standard mop may "drag." We recommend using a deck brush or a power washer on a low setting for outdoor areas to keep the ivory surface bright.

• Can I use this inside? Yes, but typically only in high-moisture areas like mudrooms or walk-in showers. For living areas, most designers pair this with the "Matt" (smoother) version of Ostuni Avorio for a matching look.

• Will it burn my feet? The Avorio color is specifically chosen for its high Solar Reflectance Index (SRI). It stays significantly cooler than dark grey or slate-colored tiles in direct sun.

PRO INSTALLATION TIPS

• The "Indoor-Outdoor" Flow: Use the Ostuni Avorio Matt (standard finish) inside your glass sliding doors and the Ostuni Avorio Grip outside. The color match is perfect, but the safety rating changes exactly where you need it.

• Back-Buttering: For 16x24 porcelain, always "back-butter" the tile. This is non-negotiable for outdoor floors to ensure no air pockets exist where moisture can collect.

• Sealing Grout: While the tile is non-porous, the grout in an ivory installation can get dirty. Use a high-quality grout sealer to keep your lines looking as fresh as the stone.
