Installation Guide – Step by Step

Step 1: Surface Preparation – Build a Solid Foundation

• Ensure the installation surface is clean, dry, and free of dust, grease, or residue.
• The substrate must be flat, stable, and crack-free for proper limestone adhesion.
• In wet areas such as showers, apply a suitable waterproofing membrane before tiling.
• Remove outlet covers, trims, and obstacles prior to layout.
• Use a leveling compound where needed to achieve a perfectly even surface.

Step 2: Layout Planning – Achieve Balance and Consistency

• Establish the center point of the wall or surface for a symmetrical layout.
• Dry-lay the 1″ hexagon sheets to preview tone variation and alignment.
• Adjust placement to minimize small edge cuts.
• Use 1–2 mm spacers between sheets for uniform grout lines.

Step 3: Adhesive Application – Use a High-Quality Thin-Set

Recommended Thin-Set Mortars (White):

• Mapei Ultraflex LFT
• Laticrete 254 Platinum
• Ardex X 5

Application Tips:

• Mix only the amount of mortar usable within 30 minutes.
• Apply mortar using the flat side of a 1/4″ notched trowel.
• Comb thin-set at a 45° angle for full and even coverage.
• Back-butter mesh-mounted sheets to ensure strong adhesion.
• Work in small sections to prevent the mortar from skinning over.

Step 4: Cutting & Fitting – Precision Matters

• Use a wet saw with a fine diamond blade designed for natural stone.
• Measure and mark cuts carefully to maintain the hexagon pattern.
• Smooth cut edges with a stone rubbing block if needed.
• Always dry-fit sheets before final placement.

Step 5: Setting the Mosaic – Maintain Pattern Flow

• Begin setting from the center and work outward.
• Press sheets firmly and evenly into the thin-set.
• Use spacers to keep grout joints consistent.
• Lightly tap with a rubber mallet to ensure level placement.
• Remove excess thin-set immediately with a damp sponge.
• Allow at least 24 hours for the adhesive to cure before grouting.

Step 6: Grouting & Sealing – Protect the Limestone

• Use unsanded or fine-grain grout to avoid scratching the honed surface.
• Apply grout diagonally using a rubber float for full joint coverage.
• Clean grout haze promptly with a soft, damp sponge.
• After initial set, lightly buff the surface with a clean cloth.
• Allow grout to cure for a minimum of 72 hours.
• Seal with a penetrating, limestone-safe sealer before use.

Maintenance Tips – Preserve the Natural Look

• Clean regularly using a pH-neutral, stone-safe cleaner.
• Avoid acidic or abrasive products that may etch the limestone.
• Reseal periodically based on usage and moisture exposure.
• Wipe spills promptly to prevent staining.

Shipping & Packaging
