Natural stone stone slab BUSH HAMMERING

for facadefor wallfor step

Overview
Bush hammering is a mechanical finishing technique that produces a textured, non-slip surface on natural stone through controlled impact with pyramidal steel points or carbide inserts. The treatment creates a consistent, rough texture that enhances grip and adds visual depth, commonly specified in architecture for exterior paving, façades and architectural details requiring anti-slip performance and material authenticity.

How it is achieved
Pistore Marmi performs bush hammering with automated rotating-head machines equipped with multiple hammers for uniform results; manual hammering by skilled operators is used for custom textures. Impact intensity and pattern density are calibrated per material to balance slip resistance, surface adhesion and visual uniformity.

Applications

• Exterior flooring and paving (walkways, external steps, outdoor terraces)
• Wall cladding and architectural façades
• Pool surrounds and other wet-area exteriors requiring anti-slip properties
• Bespoke furniture and architectural details to emphasize stone character

Material suitability and performance
Bush hammering is suitable for marble and other natural stones capable of withstanding mechanical impact. Different stone types yield distinct textures and aesthetics. The finish improves surface adhesion and provides a natural anti-slip texture while preserving the stone’s appearance. Made in Italy craftsmanship and technical calibration are applied to meet project-specific slip resistance and durability requirements.
