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 wikihow.com 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. Before the acid dries, scrub off the remaining residue with a long masonry brush while rinsing with. Liquid hydrochloric acid can’t do that.

Eco etch pro begins to work immediately upon contact without toxic hazards or dangerous skin burns associated with traditional acid formulas. This will spread the solution evenly without much splashing. It is the ideal acid etch alternative.

You roughen such a floor by etching it with muriatic acid. A smooth concrete floor must be roughened before paint will stick to it. The acid is applied on the concrete and then rinsed off with water.

In the case where you will need to etch the concrete again, muriatic acid is a more aggressive acid that should be. This has been the standard method for preparing the concrete slab for a coating or overlay. If the concrete is profiled to resemble 100 grit sandpaper or more coarse you are ready to coat.

This advanced formula incorporates a custom blend of surfactants, organic minerals and derivatives of a plant based extract for the most effective concrete etching solution available.

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. Acid etching involves allowing the reaction of a dilute hydrochloric acid solution with the concrete surface, then rinsing off with water.
