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 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
(80-100grit). 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.
If glazing or burning should occur the abrasive has dulled and must be replaced.
