60-grit drum belts must always be used after a 36-grit pass on a floor, to shrink the 36-grit scratches in the wood, so that the next grit in the sequence, 80-grit, can do the job of making the scratches almost disappear. So, 60-grit is a bit under-appreciated. Many people try to either start just at this grit, or, if they start at 36, they try to skip over straight to 80 grit. Don’t do it, my friend. In the carefully calibrated, engineered sequence of grit steps, 60 grit is irreplaceable.
