Can you coat over my old epoxy?

Only if the existing coating is sound and properly prepared. If it is loose, flaking, or failing, it should be removed so the new coating bonds to clean concrete.

How is an old coating removed?

About this service

Before a new coating can go down, an existing one often has to come off. Old epoxy, paint, or sealers that are peeling, worn, or poorly bonded will undermine a new coating applied over them. Removal uses grinding, scraping, or chemical methods depending on the existing material and the slab, then the concrete is cleaned and profiled for the new system. The condition of what's underneath determines how much removal is needed and what the slab looks like once it's gone.
