Acid etching of marble: Textured finish for stone materials
Acid etching is a controlled chemical finishing process that creates a matte, aged and textured surface on marble and travertine. The treatment reacts with the stone's porosity to form irregular surface cavities and a non-slip texture, while on harder stones such as granite the effect is mainly cleaning rather than deep etching.

Process and how it’s achieved
At Pistore Marmi the process begins with precise surface preparation and cleaning. Slabs are then exposed to calibrated acidic solutions in controlled tanks to achieve the targeted etching depth. Reaction times and solution strength are adjusted according to material type and desired intensity. The surface is neutralized with alkaline solutions and thoroughly rinsed to remove residues, ensuring stable, uniform results.

Applications and uses
Acid-etched marble and travertine are suitable for interior and exterior flooring where a textured, slip-resistant surface is required. The finish is also used for wall cladding and bespoke architectural elements to achieve an aged or natural appearance. Material selection and etch intensity are chosen to balance aesthetics and functional performance for each project.
