Ns over sanded grout. Mike Marsoun 23 Jan 2012 20:04 EST

Was wondering if this would work on a complete grind of a marble floor with sanded grout. Flatten and hone to 100 metals or 50 resins. Clean floor with a spinner. Slurry floor with a fairly loose non sanded grout and allow to dry. Then continue honing on up. Maybe re slurry at 220. Thinking the NS grout might hold together the sanded grout.
