- If you require a stone specifically rated for high-traffic commercial flooring durability, Dehbid Marble offers a higher compressive strength and specialized wear rating.
- If you need a dense marble for heavy-duty indoor use with a more uniform texture, Mahkam Marble Stone is highly suitable.
- If your project requires a wider variety of finishes like Chiseled or Bush Hammered for textured surfaces, Sanjan Marble stone provides more versatile processing options.
Important Tips When Buying Yazd Marble
- Inspect Color and Texture Consistency: Because natural stone varies by quarry and batch, always request samples from the specific production lot to check for tonal variations and veining patterns before final purchase.
- Verify Physical Properties and Standards: Ensure the stone meets your project's technical requirements. For instance, verify the compressive strength (typically 85 to 122 MPa) and water absorption (ideally 0.2% to 0.4%) to ensure it suits your environment.
- Check Surface Integrity: Carefully inspect for natural fissures, cracks, or uneven polishing. High-quality Yazd Marble should have a smooth, uniform surface according to the selected finish (Polished, Honed, or Leathered).
- Confirm Dimensions and Thickness: Standard thickness for interior flooring is typically 2 cm, while 3 cm is recommended for stairs or high-traffic areas. Verify that all tiles are calibrated for precise installation.
- Clarify Processing and Treatments: Confirm if the slabs have been treated with resin or epoxy to enhance durability and minimize natural porosity, which is particularly useful for achieving a more uniform appearance.
Maintenance and Cleaning of Yazd Marble
To preserve the luster and longevity of your Yazd Marble, follow these professional guidelines:
- Use pH-Neutral Cleaners: Avoid all acidic (vinegar, lemon) or abrasive cleaners. Use only mild, pH-neutral specialized stone soaps to prevent surface etching.
- Immediate Spill Management: Clean up acidic or oily spills immediately to prevent permanent etching or staining of the marble surface.
- Regular Sealing: Apply a high-quality impregnating sealer periodically to reduce porosity and provide a protective barrier against moisture and stains.
- Avoid Heavy Impacts: While durable for indoor use, avoid dropping heavy objects to prevent chipping or cracking of the stone edges.
