First I would not use honing powders . you will get much better results
using diamonds.  If you started with 180 grit powder  and all the damage is
out of the stone I would recommend starting with a 220 grit diamond 400 then
800 diamond and polish the floor you should get great results. Keep in mind
you need to .spend the proper time on each diamond grit in order to remove
the pervious grit scratches. If you do not spend the time on each grit you
will not remove the pervious grit scratches and the floor will never have
that great shine you are looking for.

Subject: [sccpartners] Polishing marble

Good morning.  We are working on a marble floor in a bathroom that had some
fairly deep scratches in it.  We concentrated on the deeper scratches with
an angle grinder and were able to get them out.  On the rest of the floor we
used 180 honing powders up through 3000 diamond Norton pads and we polished
with MB16 in some areas and 5x in other areas (to see if there was any
difference in the polish - there wasn't much difference).

We will probably need to grind the whole floor down and go deeper, but even
when we have done this on other floors in the past, we are not able to get a
really nice polish on it - certainly not like the factory finish.  Are we
overlooking something?  What might we try to get a better polish?  Does it
matter what sort of marble we are dealing with? A picture of the floor we
are currently working on is attached.
