Beige Diamond Marble Tile Installation Guide – Step by Step

Step 1: Surface Preparation – Stable, Clean & Level

  • Make sure the substrate is structurally sound, completely dry, and free of dust or residue.

  • Check flatness using a 10-ft straightedge—variation should not exceed 1/8″.

  • Correct uneven areas with a self-leveling compound if necessary.

  • In wet zones like bathrooms or shower surrounds, apply a waterproofing membrane for added protection.

Step 2: Layout Planning – Balance & Natural Flow

  • Mark centerlines and reference points to achieve symmetry and reduce awkward cuts.

  • Dry-lay tiles to preview the warm beige tones and natural veining of Beige Diamond marble.

  • Blend tiles from several boxes to maintain consistent color and pattern flow.

  • Use 1/16″–1/8″ grout joints for a refined, seamless look with straight-edged tiles.

Step 3: Mortar Application – White Thin-Set Required

Recommended Mortars:

  • Mapei Ultraflex LFT White

  • Laticrete 254 Platinum White

  • Ardex X77 White

Instructions:

  • Spread mortar with a 1/2″ square-notched trowel to achieve full coverage.

  • Back-butter each tile to improve adhesion and eliminate hollow spots.

  • Work in small sections to ensure thin-set remains workable before setting tiles.

Step 4: Cutting & Fitting – Smooth, Accurate Cuts

  • Cut tiles with a wet saw equipped with a continuous-rim diamond blade for marble.

  • Polish visible cut edges using marble pads or a fine stone file.

  • Dry-fit tiles before final installation to confirm alignment and sizing.

Step 5: Setting Tiles – Keep Surfaces Flush

  • Use a tile leveling system designed for large-format pieces to prevent lippage.

  • Press tiles evenly and use spacers to maintain uniform grout joints.

  • Remove any excess mortar from the polished surface immediately with a damp sponge.

  • Allow thin-set to cure for at least 24 hours before grouting.

Step 6: Grouting & Sealing – Protect the Gloss Finish

  • Pre-seal polished marble with a penetrating sealer to guard against grout stains.

  • Use non-sanded grout to avoid scratching the polished surface.

  • Apply grout diagonally with a rubber float, then clean joints carefully.

  • Buff the tile surface after 20–30 minutes to eliminate haze.

  • Once grout cures (about 72 hours), apply a second sealer coat for long-term protection.

Maintenance Tips – Keep the Shine

  • Clean only with pH-neutral, stone-safe products; never use acidic or abrasive cleaners.

  • Wipe spills immediately, especially oils or acidic liquids, to avoid staining or etching.

  • Re-seal polished marble every 6–12 months depending on traffic and exposure.

  • Protect high-use areas with rugs, mats, or felt pads under furniture.

Important Note

As a natural marble, Beige Diamond may feature variations in tone and veining. Always dry-lay and blend before installation to achieve a harmonious design. Stonemarket USA is not responsible for installation errors or natural stone variation.
