MSI Cecily Grigio 10.83" x 12.60" Polished Marble Mosaic

Product Overview

MSI Cecily Grigio 10.83" x 12.60" Polished Marble Mosaic Tile combines cool-white natural marble with soft gray accents in a sophisticated geometric pattern. Precisely cut pieces create an interlocking cube-inspired design with the illusion of architectural depth while maintaining a flat, functional mosaic surface.

The polished finish reflects light and highlights the marble’s natural crystalline character, subtle veining, and tonal movement. Its dimensional visual effect makes Cecily Grigio an elegant choice for backsplashes, bathroom walls, residential floors, shower surrounds, fireplace features, and commercial accent walls.

Part of MSI’s Bianco Dolomite Collection, this mosaic balances contemporary geometry with the timeless luxury of genuine natural marble.

Installation and Handling Guidelines

Important: Light-Marble Installation Protocol

Cecily Grigio is a light-colored natural-marble mosaic. White setting material, sealing, careful sheet alignment, and proper grout selection are essential.

• Inspect and dry-lay all sheets before installation.

• Blend sheets from several cartons to distribute natural veining and color differences.

• Rotate and reposition sheets to prevent visible sheet outlines or repetitive color concentrations.

• Install over a flat, clean, stable, and properly prepared substrate.

• Use a premium white polymer-modified mortar meeting ANSI A118.4 or A118.15 and approved for natural marble mosaics.

• Do not use gray mortar, which may shadow through or discolor light-colored marble.

• Use a small-notched trowel appropriate for the mosaic thickness.

• Flatten prominent mortar ridges before placing each sheet.

• Use a grout float or padded beating block to embed the mosaic evenly.

• Adjust individual pieces along sheet edges when necessary to maintain consistent geometric spacing.

• Achieve at least 95% mortar coverage in showers and other wet-area installations.

• Apply a penetrating natural-stone sealer before grouting.

• Use unsanded grout or a fine-aggregate grout specifically approved for polished marble.

• Test mortar, sealer, and grout on spare material before completing the installation.

• Install shower applications over a complete waterproofing system. Sealer does not replace waterproofing.

• Include perimeter and movement joints according to TCNA EJ171 and applicable construction requirements.

• Wet-cut using a clean, continuous-rim diamond blade intended for marble.

• Order approximately 10–15% additional material for cuts, pattern alignment, natural variation, and future repairs.

Grout Recommendations

• Bright White: Produces a crisp, luminous appearance.

• Warm White: Softens the geometric pattern.

• Pale Gray: Emphasizes the interlocking cube design.

• Silver Gray: Coordinates with the marble’s cool-gray accents.

Dark or strongly pigmented grout may stain light-colored marble. Always test the selected grout on spare material before installation.

Care and Maintenance

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

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

• Wipe spills promptly, especially oils, cosmetics, wine, coffee, and citrus.

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

• Avoid aggressive scrubbers that could scratch the polished surface.

• Reseal periodically according to exposure and the sealer manufacturer’s instructions.

• Protect residential floors from abrasive grit and dragging furniture.

• Use rugs or mats in entry areas to reduce scratching and surface wear.
