SANDING CUTS AND SANDPAPER
Initial Cut
The purpose of the initial cut is to remove old finish and gross imperfections on the floor surface. Use a course
(20-36 grit) grain abrasive.
Final Cuts
The purpose of a finishing 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 finishing cut, it may be necessary to use an even finer grain
of abrasive (80-100grit). Care should be taken in selecting the grit size of the abrasive. A very fi ne grain will
close the pores on a wood floor making admission of a stain difficult.
If glazing or burning should occur the abrasive has dulled and must be replaced.
