Acid Stain Concrete
ACID STAIN CONCRETE — RICH, MARBLED, ONE-OF-A-KIND COLOR
Acid staining uses metallic salts in a hydrochloric acid solution that chemically reacts with the lime content in cured concrete. The reaction produces permanent, translucent color with natural variation and marbling — no two applications look exactly the same. Popular colors include amber, walnut, cola, and verdigris. Acid stain is ideal for interior floors, patios, and commercial spaces seeking a high-end, one-of-a-kind finish.
Starting at $4 per sq ft (stain application only)

Why Choose Our Acid Stain Concrete
Acid staining is an art as much as a science. The chemical reaction between metallic salts and the lime in concrete produces rich, translucent color with natural variation that can't be replicated with paint or surface coatings. Our experienced applicators control the reaction to achieve consistent results while embracing the beautiful variation that makes each acid-stained surface unique.

FAQs About Acid Stain Concrete
Can acid stain be applied to old concrete?
Yes — acid stain works on both new and existing concrete. The concrete must be clean and free of sealers, coatings, and contaminants for the chemical reaction to occur. We assess your existing concrete to determine suitability before starting.
