Color Lab Acid Stains are reactive, mineral-acid-based solutions that chemically bond with concrete to create variegated, mottled effects. These stains etch and color simultaneously, producing a natural, weathered look with rich tonal variations. Acid Stains are a time-tested solution for creating classic, earthy finishes that become a permanent part of the concrete surface.
