Assuming the existing coating is well bonded, rent an industrial floor sander like used for hardwood floors. Use a coarse pad, and knock the glaze off. Clean thoroughly removing all dust - wash it, and dry well. Corners and edges by hand.

Bruce, I'm getting ready to do my floor. I have an issue which you may be able to address. After the concrete was poured(about a 20 months ago) I sealed it with a clear sealer(to keep it clean during construction and to slow the cure). I also had fiber added to the mix(to control micro cracks). Now I have a hairey slab. I acid washed it, and the sealer didn't allow etching. I pressure washed it, and the fibers didn't break off. I'm thinking a floor machine(buffer), with a fine screen will take the fibers down, and possibly cut most sealer off.
What would you reccomend?
Thanks, Jim
