Is etching garage floor necessary?

Why Acid Etching Is No Longer Recommended as a Concrete Prep Method. The longevity of a coating partly depends on how well it adheres to the surface of the concrete. The best adhesion requires a clean floor, free of laitance and contaminants.

In respect to this, is etching concrete necessary?

If the surface is smooth, definitely etch. However, the etching step needs to come after you clean the concrete. Phosphoric acid works on smooth or rough concrete, but you don't need its big benefit, which is its suitability for both concrete and rusted metal.

One may also ask, what happens if you don't etch concrete before epoxy? Acid etch residue on the surface Many epoxy floors have peeled up because this fine white dust was not effectively removed before the epoxy was applied. If epoxy is applied over concrete with this fine white dust, the epoxy sticks more to the dust and not the surface.

Moreover, is etching concrete necessary before painting?

In most cases, special cleaning and/or etching of the concrete surface will be required before painting, and the appropriate cleaner (often TSP, trisodium phosphate) and etcher (usually a solution of muriatic acid) can be obtained. These chemicals, especially the etcher, must be used with care.

Is etching concrete necessary before epoxy?

Concrete floors require preparation before applying an epoxy coating system. The preparation usually involves cleaning the surface to remove oil and other unwanted contaminants and "profiling" the concrete by etching with acid or by mechanical abrasion (ie; shot-blasting or etching with a diamond grinder).
