Pat, I thought about epoxies and other coatings and as hard as I am on floors (grinding, cutting, welding, dragging heavy sharp stuff around on them and general abuse) I decided against it. I used 5000 psi concrete then sprayed on a densifer to bump the surface strength up to 8000. Let it all cure and then laid down 3 coats of wax. If i scratch it or damage it I can rewax it and be good to go. If I wrecked the epoxy I would sit and cry.
Thanks for the complement.
