Acid staining is a finishing technique for concrete that mixes water, hydrochloric acid, and acid-soluble metallic salts. This mixture penetrates and chemically reacts with the hydrated lime in the concrete. The stain lightly etches the concrete surface, which allows the metallic salts to penetrate easier.
What Is Acid Staining Concrete?
Acid staining concrete is a process of adding color to concrete by using an acidic solution to penetrate the surface. Acid staining is not a dyeing or painting process, but rather a chemical reaction between the acid in the stain and the lime in the concrete.
This reaction produces permanent color changes that become a part of the concrete and will not fade, chip, or peel. Acid staining concrete is a popular way to add color to indoor and outdoor concrete surfaces such as driveways, patios, pool decks, garage floors, and even countertops.
The beauty of acid staining is that each concrete surface will produce its own unique color and finish. No two acid stained concrete surfaces will look exactly alike. Concrete acid staining is a great way to add color to your home without having to use paint or other harsh chemicals.
Acid staining is safe and easy to do, and it produces stunning results. If you‘re looking for a way to add some personality to your home, acid staining concrete is a great option.
