Decorative Concrete contractors generally clean the concrete surface by pressure washing outdoor surfaces or floor scrubbing interior floors with a buffer and abravise pad. When the surface is and also 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 with the hydrated lime in the stain producing color inside the concrete.

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