Acid Wash
Controlled acid etching creates an antiqued, vintage stone surface
Acid Wash Finish — Aged Antiqued Stone Effect
The acid wash finish involves the controlled application of a dilute acid solution to the stone surface. The acid reacts with the calcium carbonate in marble and limestone, gently etching the surface to create a softly matte, antiqued appearance. The result is reminiscent of century-old stone floors found in Tuscan villas and Rajput palaces. The finish is particularly popular for travertine and limestone for heritage and classical interior projects.

No. Acid wash relies on a chemical reaction with calcium carbonate. Since granite does not contain calcium carbonate, acid washing has no texture effect on it.
