Granite stone slab CORTEX

wallcladdinginterior

Overview
The Cortex finish is a specialized stone surface treatment that reproduces an irregular, three-dimensional, bark-like texture on natural stone. It is suitable for marble, granite and other natural stones and is primarily specified for decorative wall cladding and distinctive interior architectural elements.

How it is obtained
The finish is produced by combining high-pressure water jets with calibrated abrasive dosing. Specialized machinery sculpts the stone surface to create deeper incisions and a pronounced texture. Process parameters (water pressure, abrasive type and feed) are adjusted to control depth while preserving material integrity. The method requires higher water and abrasive intensity compared with lighter sculpting finishes.

Applications and uses
Intended for architectural cladding, feature walls and decorative elements. Different stone types respond differently to the sculpting process, yielding varied textures and visual depth. The finish is used where tactile surfaces and visual contrast are required in interior architecture and design.

Technical approach and services
Pistore Marmi combines traditional craftsmanship with advanced finishing technology to ensure controlled results. Services include calibration of finish intensity for specific stone types, technical consultation, on-site testing and provision of material samples for approval.
