When water blasting concrete in preparation for a coating, the pressure washer must be capable of delivering greater pressure than the compressive strength of the concrete being cleaned Furthermore, if your concrete has been treated with any kind of sealant or finishing coat, acid etching won't work at all. Lastly, your floor will need to be 100% completely dry before installing the epoxy coating or it will fail! The second way to prepare concrete for epoxy is by grinding the surface mechanically Chemicals such as muriatic acid, phosphoric acid or sulfamic acid are used to prepare the cement for epoxy paint.

Acid etching a garage floor is a great solution for those who are installing the floor themselves and do not have access to industrial grinders. However, for larger commercial jobs, older concrete, or worn floors we always recommend grinding before epoxy installation Unless applying epoxy mortar systems, our coatings don't require the concrete surface profile (CSP) created by shot blasting and the prior two (above) items then apply. Mechanical diamond grinding involves running a multi-head, rotating, walk behind machine with diamond tooling affixed to the heads across the entire concrete floor surface The reason for washing the residue is to neutralize the acid. So long as you properly neutralize and rinse the concrete well a couple of times, it should be fine. Note: If you do not properly neutralize the stain, then the sealer will lose it's bond, which will then have to be stripped and re-applied Once you scrub degreaser over any problem areas and they are clean, wash it away with water and allow the floor to completely dry before actually prepping the entire floor for epoxy.
