SANDING CUTS AND SANDPAPER
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.
