I'm getting ready to coat my garage floor with a two part epoxy coating. The floor is only about 5 months old and is perfectly clean except for a few light splatters of paint from when I painted the walls. Is it necessary to clean off every last splatter of latex paint off the floor before I do the acid etch and lay down the epoxy?
Been professionally installing epoxy garage floors since 2004.
It is not ABSOLUTELY necessary to clean off a few latex paint drips from the floor prior to laying the epoxy . . . BUT an ounce of prevention is worth a pound of cure. You can get a latex paint stripper at any hardware store for a couple of bucks. At the very least, sand down the drips to a scuffed up surface so the epoxy has something to grab onto.
