SANDING CUTS AND SANDPAPER

Initial Cut

The purpose of the initial cut is to remove old nish and gross imperfections on the oor surface. Use a course

(20-36 grit) grain abrasive.

Final Cuts

The purpose of a nishing cut is to remove the scratches produced during the initial cut. Use a  ne (60-80 grit)

grain abrasive. If the surface remains rough after a nishing cut, it may be necessary to use an even ner grain

of abrasive (80-100grit). Care should be taken in selecting the grit size of the abrasive. A very  ne grain will

close the pores on a wood oor making admission of a stain difcult.

If glazing or burning should occur the abrasive has dulled and must be replaced.
