Installation Guide – Step by Step

Stone Properties & Handling – Know Your Material

• Honed Finish: This basket weave mosaic tile features a smooth, matte finish that is less reflective than polished marble but is still susceptible to stains and etching if not properly sealed.
• Porosity: Dolomite marble is moderately porous. A high-quality penetrating sealer is essential to protect against moisture and stains, especially in wet areas like showers.
• Color & Variation: Expect subtle color variation and natural veining between sheets. Dry-lay sheets to align patterns and achieve a consistent look.
• Acid Sensitivity: Like all carbonate-based stones, dolomite is sensitive to acidic substances that can cause etching. Use only pH-neutral cleaners and avoid acidic spills during installation and maintenance.
• Cutting Considerations: Dolomite is relatively dense and durable but can still chip at edges. Always use a wet saw with a fine diamond blade and smooth edges after cutting.

Step 1: Surface Preparation – Start with a Clean Foundation

• Ensure the substrate is clean, dry, and free from dust, oil, and debris.
• Check that the surface is level, solid, and crack-free to ensure proper adhesion.
• Apply a waterproofing membrane in wet areas such as showers to protect against moisture infiltration.
• Remove trims, outlet covers, and any obstructions that may interfere with sheet placement.
• Use a leveling compound where necessary to create a smooth, even surface.

Step 2: Layout Planning – Maintain Pattern Consistency

• Find the center of the wall or floor to create a symmetrical and balanced layout.
• Dry-lay sheets to preview veining and pattern alignment, making adjustments to ensure consistency across the installation.
• Plan ahead to avoid small or awkward cuts at edges and corners.
• Use 1.5–3 mm spacers between sheets to maintain uniform grout lines and consistent spacing.

Step 3: Adhesive Application – Choose a Reliable Thin-Set

Recommended Brands:

• Mapei (White Thin-Set Mortar)
• Laticrete
• Ardex

Instructions:

• Mix small batches of thin-set mortar that can be used within 30 minutes to prevent premature drying.
• Use the flat side of a 1/4″ notched trowel to spread adhesive evenly over the substrate.
• Comb the mortar at a 45° angle to achieve optimal coverage and bonding strength.
• Lightly back-butter each mosaic sheet to ensure full contact and reduce the risk of lippage.
• Work in small sections to prevent the thin-set from drying before the tile is placed.

Step 4: Cutting & Fitting – Handle with Precision

• Use a wet saw with a fine diamond blade for clean, accurate cuts on the dolomite marble.
• Mark cuts precisely with a pencil or wax pencil to maintain accuracy and alignment.
• Smooth any rough edges with a stone file or rubbing block to prevent chipping.
• Dry-fit all cut pieces before final installation to ensure pattern continuity and fit.

Step 5: Setting Tiles – Keep the Pattern Flowing

• Start from the center of the layout and work outward to ensure symmetry and consistent pattern flow.
• Press each mesh-backed sheet firmly into the adhesive bed, ensuring full contact and no air pockets.
• Use spacers between sheets to maintain consistent spacing and grout lines.
• Gently tap sheets with a rubber mallet or float to achieve a level surface and even height.
• Clean any excess thin-set from the surface with a damp sponge before it dries.
• Allow the installation to cure for at least 24 hours before proceeding with grouting.

Step 6: Grouting & Sealing – Finish with Care

• Use non-sanded grout to avoid scratching the honed dolomite surface.
• Apply grout diagonally with a rubber float to ensure full joint coverage.
• Wipe away excess grout promptly with a damp sponge to prevent haze buildup.
• After 15–20 minutes, buff the surface gently with a soft, dry cloth to remove any residual haze.
• Allow grout to cure for at least 72 hours before sealing.
• Seal with a high-quality, penetrating stone sealer designed for honed marble to protect against stains and moisture.

Maintenance Tips – Keep It Looking New

• Clean regularly using only pH-neutral, stone-safe cleaners to preserve the honed finish.
• Avoid harsh or acidic cleaning products that can cause etching and dull the surface.
• Reseal periodically as recommended by the sealer manufacturer, especially in high-traffic or wet areas.
• Use felt pads under furniture to prevent scratches and surface damage.
