To remove old unwanted epoxy, we scrape and sand using a scraper and sandpaper to remove any loose or peeling epoxy. We apply a solvent such as methylene chloride or acetone to dissolve the remaining epoxy. We repeat the process until all of the old epoxy has been removed.

Next, we clean the surface thoroughly with a degreaser to remove any residual solvent and prepare the surface for the new coat of epoxy.
