Product Overview

Coronado 2" Octagon Honed Marble Mosaic Tile combines classic geometric design with the dramatic movement of genuine natural marble. Each mesh-mounted sheet features richly varied green marble octagons accented by contrasting black marble square dots, creating a sophisticated pattern with enduring architectural character.

Stony green, warm gray, creamy white, and subtle rust tones flow naturally across the honed marble surface. The low-sheen finish softens the stone’s dramatic veining while preserving its depth and organic beauty. Suitable for floors, backsplashes, shower walls, bathroom features, and decorative commercial spaces, Coronado brings timeless pattern and botanical color to both traditional and contemporary interiors.

Technical Specifications

Recommended Applications

• Bathroom Floors: The classic octagon-and-dot pattern creates an elegant natural-stone surface for primary bathrooms, powder rooms, and vanity areas.

• Shower Walls and Niches: Introduces rich green marble movement to shower surrounds, decorative bands, and recessed niches.

• Shower Floors: The smaller mosaic pieces and frequent grout joints may provide additional traction, but no published DCOF value is available. Confirm wet-floor suitability with the installer and applicable local requirements.

• Kitchen Backsplashes: Adds botanical color and historic geometric character behind ranges, sinks, and preparation areas.

• Vanity and Feature Walls: Creates a luxurious focal point behind mirrors, freestanding tubs, bars, and decorative cabinetry.

• Residential Countertops: MSI lists the mosaic for residential countertop applications. Proper sealing and careful maintenance are required.

Installation & Handling Guidelines

⚠️ IMPORTANT: NATURAL GREEN MARBLE INSTALLATION

Coronado is genuine marble with substantial natural movement. Inspect and blend all sheets before installation to distribute green, gray, cream, rust, and black elements evenly.

• White Mortar Recommended: Install with a premium white polymer-modified mortar approved for natural-stone mosaics. Gray mortar may affect the appearance of lighter marble sections.

• Dry-Lay and Blend: Open several cartons and arrange the sheets before setting them. Rotate sheets and redistribute individual pieces where necessary to prevent visible sheet outlines.

• Substrate Preparation: Install over a clean, flat, stable substrate. Shower installations require a complete approved waterproofing system.

• Mortar Application: Use a small-notched trowel appropriate for the mosaic thickness. Flatten excessive mortar ridges before placing the sheets.

• Sheet Alignment: Use a grout float or padded beating block to embed the mosaic evenly. Adjust the spacing between adjoining sheets so it matches the spacing within each sheet.

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

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

• Grout Color: Warm white, ivory, pale gray, or soft taupe can complement the marble without overpowering the octagon pattern.

• Movement Joints: Provide 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 stone. Follow crystalline-silica safety procedures and never dry-cut the material.

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

Care & Maintenance

• Clean with warm water and a neutral-pH cleaner formulated for natural marble.

• Avoid vinegar, lemon, acidic bathroom cleaners, bleach, and abrasive powders, which can etch or discolor the stone.

• Wipe spills promptly, particularly oils, cosmetics, wine, citrus, and highly pigmented liquids.

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

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

• Sealing helps resist staining but does not prevent marble from etching when exposed to acidic substances.

Design Profile

• Aesthetic Inspiration: Botanical luxury, European bistro, Art Deco, Victorian revival, organic contemporary, and modern traditional.

• Color Character: Stony green and creamy white with warm-gray movement, subtle rust accents, and contrasting black marble dots.

• Visual Advantage: The tailored octagon pattern brings structure to the marble’s expressive natural veining.

• Complementary Materials: Walnut, white oak, creamy quartz, Calacatta marble, dark-stained cabinetry, and warm plaster walls.

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

• Suggested Grout Colors: Warm white creates a crisp traditional appearance, while pale gray or soft taupe provides gentler definition.

Frequently Asked Questions

Is CalaVerde Coronado genuine natural marble?

Yes. Coronado is a genuine natural-marble mosaic rather than a marble-look porcelain product.

What colors appear in the mosaic?

The marble combines stony green, warm gray, creamy white, and occasional rust-toned movement. Contrasting black marble squares define the octagon pattern.

Is the finish polished or honed?

This product has a smooth honed finish with a soft, low-sheen appearance.

What is the official MSI item number?

The manufacturer item number is SMOT-COR-2OCTH.

Can Coronado be installed on shower walls?

Yes. It is suitable for shower walls when installed over a properly waterproofed substrate using setting materials approved for natural marble.

Can it be used on a shower floor?

It may be considered for shower floors because mosaic grout joints can improve traction. However, MSI does not publish a DCOF value for this natural-stone mosaic, so the installer should confirm suitability for the specific project.

Does Coronado marble require sealing?

Yes. A penetrating natural-stone sealer is recommended before grouting and periodically after installation.

Will every sheet look the same?

No. Differences in green intensity, veining, cream coloration, gray movement, rust markings, and black-dot appearance are inherent characteristics of natural marble.

Can acidic cleaners be used on this mosaic?

No. Acidic products can etch marble and permanently dull the honed surface. Use only a neutral-pH natural-stone cleaner.
