Technical Specifications

Installation & Handling Guidelines

⚠️ CRITICAL WARNING: NATURAL MARBLE PROTOCOL

• White Thinset Mortar Mandatory: ALWAYS install natural marble using a white polymer-modified thinset mortar (such as MAPEI® Ultraflex 2 White or LATICRETE® 254 Platinum White). Standard grey mortars can shadow through translucent light calcite veins and alter the natural stone color.

• Sealing Prior to Grouting (Required): Natural marble is porous. Apply a high-quality impregnating stone sealer (like Miracle 511 Impregnator) to tile surfaces before grouting. This prevents grout pigments (especially grey or dark grouts) from penetrating the polished surface pores.

• Grout Selection: Use non-sanded grout or fine-aggregate grout (such as MAPEI® Ultracolor Plus FA) to avoid micro-scratching the polished marble surface during float application.

• Wet Zone Waterproofing: When installing in wet bathroom areas, ensure an approved continuous waterproofing membrane is applied to the substrate before setting tile.

Professional Recommendations

• Dry Lay & Shade Blending: Rosso Levanto marble exhibits high color and veining variation (V4 rating). Unbox and dry-lay tiles across the floor prior to installation to randomize deep red tones and white veining patterns.

• Grout Color Pairing: Pair with a soft cream, light warm grey, or off-white grout to frame each 12x12 tile cleanly without clashing with the white calcite veining.

Care & Maintenance

• Routine Cleaning: Wipe down or mop using warm water and a pH-neutral natural stone cleaner.

• Avoid Acidic Cleaners: Never use vinegar, bleach, ammonia, citrus cleaners, or harsh abrasive powders. Acids will etch natural calcite and permanently dull the polished finish.

• Annual Sealing: Re-apply a penetrating natural stone sealer once a year (or per manufacturer recommendations) to protect against oils, wine, cosmetic spills, and water stains.

Frequently Asked Questions

Can 12x12 Rosso Levanto Polished Marble be used on shower floors?

Polished marble can become slippery when wet. While 12x12 polished tiles work exceptionally well for main bathroom floors, powder rooms, and shower walls, a smaller mosaic format (e.g., 2x2 grid or basketweave) or a honed surface is recommended for walk-in shower floors to provide adequate foot traction.

Why is sealing natural marble necessary before grouting?

Natural marble contains micro-pores. Unsealed marble can absorb moisture and pigments from wet grout, leaving behind permanent grout haze staining around tile edges. Sealing beforehand creates a protective barrier for easy grout cleanup.

Does Rosso Levanto require special maintenance compared to porcelain?

Yes. Unlike non-porous porcelain, natural marble requires pH-neutral cleaners and periodic re-sealing. Avoid acidic liquids to maintain its high-gloss mirror shine.
