Concrete thickness can vary from 1/4 inch to over 3 feet. However, depending on the finish (how it was troweled) and porosity of the concrete surface, the penetration of the acid reaction may be only 1/16 inch to 3/16 inch. In time, if the surface is not maintained, the floor finish, sealer and color can be worn off exposing bare concrete areas.
