  • Why Acid Etching Is No Longer Recommended as a Concrete

    What Is Etching Concrete. Acid etching is the process of applying hydrochloric/muriatic or buffered phosphoric acid to a slab then rinsing it off with water. For many years it was a standard method of concrete preparation used by nearly all industrial commercial and institutional floor coating installers depending on the floor size and If the first application of acid does not remove the cement repeat the application with a slightly stronger acid solution such as 1 part acid to 10 parts water.
