I have no idea! I would assume it's the industrial paint for floors- it would have to be waterproof and skid-proof, so you'd need some sand or something mixed in the paint to make sure it's not slippery when wet!
2 part epoxy garage floor. I have used it in my last 3 houses. I have tried the gray, tan, and blue. I liked the gray by far over the others. Oh and do the pretty little paint chips. You can also add the grit designed for the epoxy for a slip resistant finish.
