Help! Want to sand limestone in desperation!

[marawoods]

1. I’ve scrubbed and scrubbed my large foyer's 16X16 honed limestone--even with a power scrubber and Simple Green tile cleaner, as well as other tile cleaners.
2. Still looks bad (grayish and blotchy).
3. It originally was a nice uniform antique white from Turkey with large "craters" throughout, with some hints of coral. Professionally installed and craters were filled--not sure with what...some filled holes seem to match the bone grout; others seem different...looks like a dense beige product (tiles were set in grey mortar, so don't think I'm looking at dried mortar).
4. Currently using MiraSoap. Realize that former cleaning products may have had undesirable reaction with calc. carb. Have not yet tried a vinegar wash.
5. NO LONGER WANT TO SCRUB--fruitless.
6. QUESTION: Can I just get a power sander and just grind off the top layer, with the hope of giving my floor a fresh start?
7. Alternatively, how reckless would it be to cover the whole floor with a wash of antique white paint, and then apply impregnator to that?
8. Would be very grateful for seriously helpful replies!

Well, I'm sure that you could sand the surface, and even get a decent honed finish yourself. But before doing that, Have you given the stone a good chance to dry out after all that scrubbing and scrubbing??? Many limestones are very porous and absorptive, and could take days or even longer to dry completely after a good washing.

Hold your horses, don't get rash with your stone,it can be beautiful again given the right care.Johns right about the waiting, but i think you may have taken off the surface with all your scrubbing,especially if you used tile cleaning products instead of neutral cleaners.You will most likely need to call a restoration specialist in your area to give it a honing again to restore it's uniform look,after you put a fan on it a couple days .Read around here and pick up some nowledge about caring for stone.Aquamix, Stonetech,Miracle, they all have websites and handouts for care and maintenance of stone.
