Acid-stained concrete is different from dying or coloring concrete. Instead of ‘adding’ color to the top of a concrete surface, acid staining leverages a chemical reaction to bring brilliant colors out of your concrete slab. This permanent chemical bond runs 1/16” to 1/32” into your concrete slab, so the new natural color goes beyond just the surface. If your floor chips or cracks a bit over time, the underlying concrete matches the color and adds texture. Acid-staining concrete creates earthy tones that add a beautiful, natural metallic look.
