Product Overview

 Calacatta Green & Bianco Dolomite Chex 6" × 6" Honed Marble Mosaic Tile reimagines the timeless checkerboard floor through richly expressive natural stone. Alternating squares of dramatic Coronado marble and soft white Bianco Dolomite create a bold geometric pattern balanced by an elegant honed finish.

Coronado contributes blue-green, warm gray, creamy beige, and rust-colored mineral movement, while Bianco Dolomite introduces a quiet white background with delicate gray veining. Together, the two marbles create a striking contrast suited to bathroom floors, entryways, backsplashes, shower walls, and statement interiors ranging from classic European to modern organic.

Installation & Handling Guidelines

⚠️ IMPORTANT: TWO-MARBLE COLOR-BLENDING PROTOCOL

Coronado and Bianco Dolomite are genuine natural marbles. Differences in color, veining, mineral markings, and contrast are expected. Dry-lay the sheets before installation to create a balanced checkerboard composition.

• White Mortar Required: Install with a premium white polymer-modified mortar approved for natural-stone mosaics. Gray mortar may discolor or shadow through the lighter Bianco Dolomite pieces.

• Dry-Lay and Blend: Open several cartons and arrange all sheets before setting them. Distribute strongly veined and lightly veined pieces throughout the installation.

• Substrate Preparation: Install over a clean, flat, stable substrate. Shower and wet-area applications require a complete approved waterproofing system.

• Mortar Application: Use a small-notched trowel appropriate for the mosaic thickness. Flatten the mortar ridges before positioning the sheets to prevent show-through and uneven elevation.

• Checkerboard Alignment: Check the square pattern frequently during installation. Adjust the spacing between sheets so it matches the joints within each sheet.

• Pre-Sealing: Apply a penetrating natural-stone sealer before grouting to reduce pigment absorption and simplify cleanup. Test the product on spare material first.

• Grout Selection: Use unsanded grout or a fine-aggregate grout specifically approved for honed marble. Test the grout to ensure it will not scratch or discolor either stone.

• Grout Color: Warm white provides crisp contrast, while light gray or soft taupe produces a more integrated appearance.

• Movement Joints: Include perimeter and field movement accommodation according to TCNA EJ171 and applicable construction requirements.

• Cutting: Wet-cut with a clean continuous-rim diamond blade designed for natural marble. Never dry-cut or grind the material.

• Order Allowance: Add approximately 10–15% for cuts, natural-stone selection, breakage, and future repairs.

Care & Maintenance

• Clean regularly with warm water and a neutral-pH natural-stone cleaner.

• Avoid vinegar, lemon, acidic bathroom cleaners, bleach, abrasive powders, and harsh grout cleaners.

• Wipe spills promptly, especially oils, cosmetics, wine, citrus, and strongly pigmented liquids.

• Use soft microfiber cloths, non-abrasive sponges, or soft-bristle brushes.

• Apply a penetrating natural-stone sealer periodically according to exposure and the sealer manufacturer’s recommendations.

• Sealing improves stain resistance but does not prevent marble from etching when exposed to acidic substances.

Design Profile

• Aesthetic Inspiration: European checkerboard floors, Parisian interiors, Art Deco, modern traditional, botanical luxury, and contemporary eclectic design.

• Color Character: Soft white and gentle gray contrasted with expressive blue-green, warm beige, and rust-colored marble movement.

• Visual Advantage: The simple checkerboard geometry brings structure and balance to the dramatic natural variation of Coronado marble.

• Complementary Materials: Walnut, white oak, creamy quartz, aged plaster, fluted wood, and solid white marble.

• Complementary Metals: Unlacquered brass, antique bronze, polished nickel, champagne bronze, and matte black.

• Suggested Grout Colors: Warm white emphasizes the checkerboard pattern, while light gray or pale taupe softens the contrast.
