  • Sealing: Periodic sealing enhances stain resistance, especially in high-traffic or exposed areas.
  • Avoid: Use of acidic or abrasive cleaners that can damage the surface.

Cutting Sizes

  • Standard Slabs: Available in standard slab sizes, typically around 2-3 cm thick.
  • Custom Sizes: Can be cut into custom sizes based on project requirements, generally accommodating dimensions common in stone applications.

Available Surface Finish Options

  • Polished: Provides a glossy, reflective surface enhancing the stone’s color and patterns.
  • Honed: Offers a smooth, matte finish that is less reflective.
  • Flamed: Produces a textured, slip-resistant surface ideal for outdoor use.
  • Brushed: Gives a slightly textured finish while maintaining a level of smoothness.
  • Split-faced: Offers a rugged, natural look perfect for rustic designs.
