This floor will take a LOT of abuse with dropped objects and scraping by a front loader. Thanks! David G.

I would use a high-strength concrete floor topping with emery aggregate. This would be a bonded installation about 2-inches thick over the structural slab. Ronald L.

I once spec'd on a project in which contractor didn't have sufficient quantity for needed/required thickness. Project's slab ended up having less thickness than recommended for loads, abuse, slab was to be subjected to.
