Installation & Handling Guidelines

⚠️ IMPORTANT: WHITE MARBLE MORTAR AND SEALING PROTOCOL

Thassos is a light-colored natural marble. Proper mortar selection, coverage, sealing, and handling are essential to preserve its clean white appearance.

• White Mortar Required: Install with a premium white polymer-modified thin-set or natural-stone mortar meeting ANSI A118.4 or A118.15. Gray mortar may discolor or shadow through light marble.

• Pre-Installation Inspection: Dry-lay tiles and inspect them under the project’s lighting. Natural differences in crystal structure and tone are inherent characteristics rather than manufacturing defects.

• Mortar Coverage: Directionally trowel mortar and back-butter tiles where necessary. Achieve at least 95% coverage in shower and wet-area installations.

• Pre-Sealing: Apply a penetrating natural-stone sealer before grouting, particularly on honed surfaces, to reduce grout-pigment absorption and simplify cleanup.

• Grout Selection: Use unsanded grout or a fine-aggregate grout approved for polished natural stone. Test grout on a spare tile before installation.

• Grout Joint: A joint of approximately 1/16" to 1/8" may be used depending on tile calibration, substrate conditions, and installer recommendations.

• Wet-Area Preparation: Install shower applications over a complete waterproofing system. Sealer does not replace waterproofing.

• Cutting: Use a clean, continuous-rim diamond blade designed for marble. Wet-cut material and follow appropriate silica-dust safety procedures.

• Order Allowance: Add approximately 10–15% for cuts, breakage, shade selection, and future repairs. Complex patterns may require additional material.

Care & Maintenance

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

• Avoid vinegar, lemon, bleach, acidic bathroom cleaners, and abrasive powders, which can etch or dull marble.

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

• Reapply a penetrating natural-stone sealer periodically based on use, exposure, and the sealer manufacturer’s recommendations.

• Use soft cloths, microfiber pads, or non-abrasive brushes to protect the finished surface.

Design Profile

• Aesthetic Inspiration: Greek classical luxury, contemporary minimalism, coastal elegance, and Art Deco glamour.

• Visual Advantage: The brilliant white crystalline field reflects light and gives compact rooms a brighter, more expansive appearance.

• Layout Options: Horizontal running bond, vertically stacked, traditional brick pattern, offset vertical, and herringbone.

• Complementary Materials: Calacatta Gold marble, Ming Green marble, white oak, walnut, lacquered cabinetry, and clear glass.

• Complementary Metals: Polished chrome, champagne bronze, brushed nickel, and matte black.

• Suggested Grout Colors: Bright white creates a seamless appearance, while pale gray subtly emphasizes the elongated format.

Frequently Asked Questions

Is this genuine Thassos marble from Greece?

Yes. It is genuine natural marble quarried on the Greek island of Thassos and recognized for its exceptionally bright crystalline-white appearance.

What is the difference between polished and honed Thassos marble?

Polished marble has a glossy, light-reflective surface that intensifies its crystalline brilliance. Honed marble has a softer, low-sheen appearance and generally provides better traction for suitable floor applications.

Does Thassos White marble require sealing?

Yes. Apply a penetrating natural-stone sealer before grouting and reseal periodically based on the installation environment.

Can it be installed on shower walls?

Yes. The 3" x 12" format is well suited for shower walls when installed over an approved waterproofing system with white natural-stone mortar.

Can polished Thassos be used on a shower floor?

Polished marble is generally not recommended for shower floors because it may become slippery when wet. A suitable honed mosaic or smaller-format tile is normally a better choice.

Will every tile be completely uniform?

No. Thassos is a natural stone, so slight differences in tone, crystal structure, and occasional mineral markings should be expected.
