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.
