Decorative Concrete contractors generally clean the concrete surface by pressure washing outdoor surfaces or floor scrubbing interior floors with a buffer and abravise pad. After the surface is clean and the surrrounding walls are prepped the applicator will spray stain to the floor. Most chemical stains really are a mixture of water, hydrochloric acid, and acid-soluble metallic salts. They work by reacting chemically using the hydrated lime within the stain producing color within the concrete.

When acid stain is used to a concrete surface it creates a mottled, uneven, translucent color. This coloring process provides surface a look much like weathered stone, slate or marble. Since each layer of concrete has a slightly different chemical combination colors in concrete can differ. Acid Staining unlike paint isn't a coating. Therefore, the colour becomes a permanent section of the surface and will not chip, flake or peel. Since acid stain is translucent cracks as well as other imperfections in the slab give a weathered look of character.

The acid within the stain reacts with the lime inside the concrete and the chemical reaction will change the color of the concrete.
