Acid etching as a surface preparation is the process of applying an acid solution to a concrete surface, allowing the acid to react with and ‘etch’ the concrete. Etching removes the weak cement paste and profiles the surface slightly by exposing the fine aggregate and opening the pores of the concrete. This is usually considered a concrete preparation step done before the application of a concrete sealer, thin-film epoxy, or other concrete coating.
