Sanding Cuts and Sandpaper
(See chart on page 14)
Initial Cut
The purpose of the initial cut is to remove old finish and
gross imperfections 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.
