Just over a year ago, my paint contracting company prepped and finished a 4500 sf concrete floor in a warehouse for a bread distribution company. Recently, at the one year mark, I went back to inspect the floor to see how it was holding up to fork lift, hand trucks, foot traffic and the hundreds of pallets that get slid around on it daily.
I wish I had more thumbs to give thumbs up to the ArmorSeal epoxy coating we used. The floor had a base coat of gray, yellow grids with stenciled letters for shipping/receiving locations, and a white perimeter safety band. I could not be more impressed with how this floor is holding up to the industrial traffic it is exposed to daily.
ArmourSeal is a hardcore coating that I would not recommend for use by do it yourselfers. There are other suitable products for residential concrete coatings, but for contractors who need to know that the product is as badass as can be, this is a good one. As always, prep is the key, proper mixing, follow the spec sheet for sweat ins and pot life, and without a doubt, wear respirators!
