How to Choose the Right Natural Stone for Your Project

Start With the Application, Not the Aesthetic

The most common mistake buyers make when specifying natural stone is choosing based on appearance first and then discovering, too late, that the stone is technically unsuitable. The right stone for a Michelin-star restaurant kitchen countertop is very different from the right stone for a hotel lobby floor or an exterior building facade.

Flooring: Hardness, Slip Resistance, Traffic Volume

For flooring applications, hardness and finish are everything:

• Granite (Mohs 6–7) — the industry workhorse. Scratch-resistant and low-maintenance; the default choice for commercial high-traffic floors.
• Quartzite (Mohs 7) — premium alternative to marble with superior durability; excellent for upscale residential flooring.
• Marble (Mohs 3–4) — beautiful but softer. Best limited to residential bedrooms and bathrooms where heavy traffic isn't an issue.
• Travertine (Mohs 3–4) — warm and characterful; great for spa environments and hotel lobbies when properly filled and sealed.
• Sandstone (Mohs 6–7) — naturally textured and slip-resistant; ideal for exterior terracing and pool surrounds.

For wet or exterior areas, always specify honed, flamed, or bush-hammered finishes. Polished stone is dangerously slippery when wet.

Exterior Cladding: Weather Resistance Is Non-Negotiable

Exterior cladding faces freeze-thaw cycles, UV exposure, and thermal movement. Key technical parameters:

• Water absorption — For exterior cladding, specify stone with absorption below 0.4% (granite typically <0.2%). High-absorption stone cracks in cold climates.
• Flexural strength — Thin panel formats (20–30mm) used in facade systems need minimum 10 MPa flexural strength.
• Frost resistance — Ask your supplier for EN 12371 freeze-thaw test results if specifying for cold climates.

Countertops: Porosity and Chemical Resistance

Kitchen countertops are exposed to acids, oils, and impact daily:

• Granite — non-porous, hard, chemically resistant. The practical gold standard for kitchen counters.
• Quartzite — harder than marble, sophisticated aesthetics; an excellent premium upgrade.
• Marble — stains and etches from acids. Treat it as a living material that develops patina — some love it, others don't.
• Soapstone — non-porous and naturally oil-resistant; a niche but excellent island option.

Always Request Technical Data Sheets

Before finalising any specification, ask your vendor for water absorption test results (EN 13755), flexural strength data, and slip resistance ratings (PTV value). Verified LithoPrime vendors provide these on request. Use the Quarry Network to search suppliers by stone type and country, and message them directly through the platform.
