Sanding Cuts and Sandpaper

Initial Cut
The purpose of the initial cut is to remove old fi nish and gross im-
perfections on the fl oor 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 fi nishing cut is to remove the scratches produced
during the initial cut. Use a fi ne (60-80 grit) grain abrasive.
If the surface remains rough after a fi nishing cut, it may be necessary
to use an even fi ner grain of abrasive
(80-100 grit). Care should be taken in selecting the grit size of the
abrasive. A very fi ne grain will close the pores on a wood fl oor making
admission of a stain diffi cult.
