We just built a killer new shop, and we're considering putting down one of those cement coatings to protect the floor. I went to the hardware store, and they had one part epoxy, two part epoxy, regular old paint, etc. All of it was in one gallon containers. This is a 60X80 shop, so we'll need bulk. Our main intention is to protecte the concrete and make it easier to keep clean. Has anybody done this before? Please offer suggestions.
