The sample piece was scratched and scuffed.
We didn't even think to take a picture before we started.
The diamonds are from Italy made specifically for engineered stone.
We ran a ceramic type aggressive diamond to remove all the abrasion.
Then from 60g up thru the grits and including 600g to 1800g-then polish with MB-20.
Here's another sample of a floor we will be doing soon.
Uba Tuba-600 SF from honed to antiqued finish.
We did this sample with a hand grinder and 5 inch diamond brushes.
24g 36,46,80,180,220 and color enhanced.
There are many opportunities out there for stone refinishers!
