What Is Concrete Acid Stain?
This type of stain is quite different than what you normally think about when you think “stain”. It is actually a combination of water, hydrochloric acid, and metallic salts. Since concrete is such a porous material, the solution works by penetrating the surface and changing the composition of the floor with a chemical reaction. Since you are actually changing the floor, and not just painting something on the surface, the color will not chip, peel, or fade. The colors you will get with an acid concrete stain are usually earth-toned, and the results should mimic marble, wood, or expensive stone.
