Installation Guide – Step by Step

Step 1: Surface Preparation – Build a Lasting Base
Begin with a surface that’s thoroughly cleaned and free from dust, oils, or residues—this ensures a strong, lasting bond.
Confirm the substrate is level, solid, and crack-free, providing a flawless canvas for Dolomite & Bardiglio Siena marble.
In wet areas such as showers, apply a high-quality waterproofing membrane to protect the stone from moisture damage.
Remove trims, outlet covers, or other obstructions that could disrupt the smooth flow of the Siena pattern.
Use a leveling compound if necessary to create a perfectly even surface ready for installation.

Step 2: Layout Planning – Highlight Natural Elegance
Locate the center of your installation area to achieve balance and symmetry.
Dry-lay a few sheets to appreciate the interplay between Dolomite’s white background and Bardiglio’s smoky veining—each sheet is unique.
Adjust the layout to prevent small, awkward cuts at edges, ensuring a seamless, flowing pattern.
Use 1.5–3 mm spacers between sheets for consistent grout lines and a professional finish.

Step 3: Adhesive Application – Choose Reliable Thin-Set

Recommended Brands (Natural Stone-Friendly):

Mapei – dependable quality for natural stone.
Laticrete – superior adhesion and professional-grade workability.
Ardex – perfect for precision installations with premium stone.

Instructions:
Use a white, non-staining thin-set mortar to maintain the polished finish and avoid discoloration.
Mix small batches that can be applied within 30 minutes for consistent performance.
Apply adhesive with a 1/4″ notched trowel—first coat the surface flat, then comb at a 45° angle.
Back-butter each sheet to enhance adhesion and reduce lippage, keeping the polished surface smooth.
Work in sections to prevent the thin-set from drying before sheets are set.

Step 4: Cutting & Fitting – Precision and Care
Use a wet saw with a fine diamond blade for clean, chip-free cuts.
Mark cuts carefully with a pencil to ensure accuracy.
Smooth edges with a stone file or rubbing block to preserve the polished finish.
Dry-fit sheets to confirm pattern flow—Dolomite & Bardiglio Siena marble deserves a seamless display of its natural veining.

Step 5: Setting Tiles – Master the Mosaic
Start from the center and work outward to maintain symmetry.
Press mesh-backed sheets gently into the thin-set, allowing the marble’s character to shine.
Use spacers for consistent grout lines and a refined, professional look.
Lightly tap tiles with a rubber mallet to level and prevent lippage.
Wipe excess thin-set immediately with a damp sponge to preserve the polished surface.
Allow at least 24 hours of curing before grouting.

Step 6: Grouting & Sealing – Protect Your Investment
Use non-sanded grout to avoid scratching the polished marble.
Apply grout diagonally with a rubber float, filling all joints completely.
Wipe off excess grout promptly with a damp sponge to prevent haze.
Buff any remaining haze after 15–20 minutes with a soft, dry cloth.
Let grout cure for 72 hours, then apply a penetrating marble-safe sealer to protect against stains, moisture, and etching.

Maintenance Tips – Preserve the Shine
Clean only with pH-neutral stone cleaners.
Avoid acidic or abrasive products that can dull or damage the surface.
Reseal periodically according to usage and exposure.
Use felt pads under furniture to prevent scratches and maintain the tile’s polished beauty.

Shipping & Packaging – Carefully Delivered
Each mosaic sheet is individually wrapped and securely packaged to minimize breakage. The mesh backing ensures precise alignment of the Siena pattern, preserving the tile’s refined aesthetic.
