Specifications called for a smooth steel trowel finish of concrete in the gym lockers. Concrete etch and cleaner is a cleaner and etch combination that opens the pores of concrete surfaces to allow coatings to penetrate and achieve a proper bond. The post is based on a very informative article on titled, how to acid etch concrete.

These concentrated solutions use a mild acid typically (phosphoric) to lightly etch the surface for your new epoxy coating. For acid etching, a muriatic (hydrochloric) acid solution is spread on the concrete and brushed across the surface with a floor machine equipped with nylogrit brush used for etching and then is rinsed away. Don’t acid etch in weather below 50 degrees f.

Acid etching concrete creates only a minimal profile. Concrete surface profile, or csp, as defined by the international concrete repair institute (icri), is a standardized measure for the ‘roughness’ of a given concrete surface. Paint will not stick to oily concrete, so be sure that any grease and oil stains are cleaned as thoroughly as possible.

Etching concrete with vinegar acid etching with vinegar is easy and less labor intensive than using a machine to pretreat the concrete floor before sealing or painting.

Cleaning concrete, bricks, and pavers with an acid (most often referred to as acid etching or acid washing) is a very bad idea and no longer recommended by many coatings manufacturers. Concrete is a durable building material that takes special materials to dissolve once it's hardened into place.
