Important Considerations for Natural Stone

  • 🔹 Porosity: Marble is naturally porous; regular sealing is essential to prevent stains
  • 🔹 Veining: Each slab is unique – expect natural variations in color and pattern
  • 🔹 Durability: Best suited for low-traffic areas; avoid acidic spills (lemon, vinegar)
  • 🔹 Care: Clean with mild soap and water; avoid harsh chemicals

Ordering Information

All countertops are cut-to-order. Please confirm your exact dimensions, thickness, finish, and edge profile before purchase.

Installation Guide for Professionals


Pre-Installation Checklist

  • Inspect the Slabs: Carefully examine each slab for natural fissures, cracks, or weak spots. Mark any areas needing extra support
  • Check the Substrate: Ensure base cabinets are level and sturdy. Use shims if needed to avoid stress fractures
  • Prepare for Weight: Marble is heavy. Confirm your crew can safely lift and maneuver slabs without chipping edges

Key Installation Steps

  • Use the Right Adhesive: Apply high-quality, two-part epoxy or polyurethane adhesive specifically for marble. Avoid water-based glues that can stain
  • Support the Seams: Use color-matched epoxy to blend veins. Clamp pieces tightly for 24 hours for nearly invisible seams
  • Handle with Care: Always lift slabs vertically, not flat. Use suction cups for large pieces. Protect edges with foam pads

Polishing and Finishing Tips

  • Final Polish: Use marble-specific polishing compound with a soft pad. Buff in circular motions to restore luster. Avoid wax-based products
  • Edge Detail: Use a wet polisher with diamond pads (50 grit to 3000 grit). Keep stone wet to prevent heat damage
  • Seal the Surface: Apply penetrating sealer after polishing. Let it soak for 15 minutes, then wipe off excess

Common Mistakes to Avoid

  • Don’t Use Acidic Cleaners: Vinegar, lemon juice, or bleach etch marble instantly. Use pH-neutral stone cleaners
  • Avoid Over-Tightening: When fastening undermount sinks, don’t over-tighten brackets – this can crack the marble
  • Watch for Water Rings: Use felt pads under appliances to prevent moisture absorption and dark rings

Final Recommendations

Marble is a luxury investment. Remind clients to seal every 6-12 months and use coasters. With proper care, it will last a lifetime.
