Sanding Cuts and Sandpaper
Initial Cut
The purpose of the initial cut is to remove old finish and gross im-
perfections on the floor surface. A coarse abrasive should be used.
If glazing, loading, or burning takes place immediately into an initial
cut, select a coarser abrasive. If this should occur during an initial cut,
the abrasive has dulled and must be replaced.
Final Cuts
The purpose of a finishing cut is to remove the scratches produced
during the initial cut. Use a fine (60-80 grit) grain abrasive.
If the surface remains rough after a finishing cut, it may be necessary
to use an even finer grain of abrasive
(80-100 grit). Care should be taken in selecting the grit size of the
abrasive. A very fine grain will close the pores on a wood floor making
admission of a stain difficult.
