What are acid stains on concrete?
Concrete acid stains are a way to color concrete. But they work very different from a water based stain or paint. Unlike concrete paint or water based stains, acid does not sit on the surface of the concrete. Rather, it penetrates deep into the pores of the concrete and actually changes it’s color forever.
Are concrete stains safe?
And in some cases, these newer stain products are easier and safer to apply. Concrete stains are a mixture of water, hydrochloric acid, and acid-soluble metallic salts. Because of concrete's porous qualities, they penetrate and react chemically in the concrete. Concrete stains become a permanent part of the concrete.

What is concrete acid stain made of?
Acid stains are chemically reactive and basically made of hydrochloric acid, blends of metallic salts, and water. Once the hydrochloric acid breaks through the tight cream at the surface of the concrete, the metallic salts get in and react chemically with the free lime at the surface of the concrete.
