Installation and Handling Guidelines

⚠️ CRITICAL WARNING: NATURAL MARBLE MOSAIC PROTOCOL

• White Mortar Requirement: ALWAYS set natural marble using a white polymer-modified thinset mortar (such as MAPEI® Ultraflex 2 White or LATICRETE® 254 Platinum White). Dark or grey mortars will bleed through translucent marble and permanently alter its color.

• Sealing Prior to Grouting (Mandatory): Natural marble is porous. Apply a high-quality impregnating natural stone sealer to the mosaic sheet before grouting. This prevents grout pigments (especially dark or grey grouts) from staining the marble's polished surface and micro-pores.

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

• Wet Area Waterproofing: When installing in showers or wet areas, ensure an approved continuous waterproofing membrane (like Schluter®-KERDI or RedGard®) is applied to the substrate before setting.

Professional Recommendations

• Dry Lay & Color Blending: Calacatta Viola marble inherently features extreme color and veining variation (V4). Lay out multiple 12x12 sheets across the floor prior to setting to balance dark plum veining and lighter cream background fields.

• Grout Color Pairing: Pair with a soft cream, light warm grey, or off-white grout to frame the individual tesserae cleanly without overpowering the natural stone veining.

Care and Maintenance

• Sealing Maintenance: Re-apply a premium stone impregnator sealer once per year (or per manufacturer guidelines) to maintain stain protection against oils, wine, and soap scum.

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

• Avoid Acidic Cleaners: Never use vinegar, bleach, ammonia, or harsh abrasive scouring powders. Acids will etch and permanently dull polished natural marble.

Frequently Asked Questions

Can Viola Marble Tessere Mosaic be used on shower floors?

While polished marble can be installed on residential shower floors due to grout joints offering foot traction, polished surfaces can be slippery when wet. If used on a shower floor, ensuring proper slope and using an adequate grout joint width (1/16" to 1/8") is essential. Honed marble is often preferred for high-slip shower floors, while polished is ideal for shower walls.

How do I maintain the high shine on polished marble?

Routinely clean with a non-acidic, pH-neutral stone soap and re-seal annually with an impregnating sealer. Avoid abrasive scrubbing pads that can create micro-scratches on the polished finish.

Is sealing required before and after installation?

Yes. Seal the marble before grouting to protect it from grout haze and pigment absorption, and seal it again after grouting to protect both the stone and grout lines from moisture and staining.
