Concrete Staining

Acid-based chemical stains react with the minerals that make up a concrete slab. The result is an etched surface in a range of earthy tones. Staining can create the look of natural stone to polished marble to stained wood.

These stains are semi-transparent so do not cover any cracks or preexisting color. Proper surface preparation is done for the proper result.

Most acid stains are a mixture of water, hydrochloric acid, and acid-soluble metallic salts. They work by penetrating the surface and reacting chemically with the hydrated lime (calcium hydroxide) in the concrete. The acid in the stain lightly etches the surface, allowing the metallic salts to penetrate more easily.

Stained concrete is one of the easiest ways to enhance an indoor and outdoor space. From staining an existing surface to resurfacing damaged concrete and replacing worn-out floor coverings, the floors can become better than new with durable, decorative concrete.
