Sandblasted marble is a textured, matte finish achieved by firing a high-pressure stream of sand, grit, or small metal beads at the surface of the stone. This process “etches” the marble, creating a uniform, pitted texture that is both tactile and visually softened.

Key Characteristics

• Aesthetic: It mutes the stone’s natural colors and reduces the sharpness of the veining, resulting in a sophisticated, understated look. A deep wine-red marble like Rosso Laguna, for example, would shift from a glossy burgundy to a soft, dusty rose or muted plum.

• Slip Resistance: The primary functional benefit is its high “COF” (Coefficient of Friction). The roughened surface provides excellent grip, making it far safer than polished marble in wet conditions.

• Durability: The texture effectively hides scratches, fingerprints, and the “etching” marks typically caused by acidic spills, which would otherwise be glaringly obvious on a polished surface.

Applications & Performance

In Ultra-Thin & BIM Contexts

• Weight Efficiency: Sandblasting is often applied to ultra-thin laminate marble to create “anti-slip” lightweight panels for luxury yacht decks or high-end shower trays.

• BIM Integration: In BIM catalogs, sandblasted marble is categorized by its “roughness” value, allowing architects to accurately simulate light diffusion (no glare) and safety specifications for public floor areas.

• Structural Integrity: Because sandblasting is a high-impact process, it is typically performed on the stone before it is sliced into ultra-thin 0.5 mm layers or while it is already bonded to a structural backing like aluminum honeycomb to prevent breakage.
