Sanding Cuts and Sandpaper
GENERAL CUTTING
As the machine is designed to have a random cutting pattern, any direction of travel is permitted, however it
is recommended that the machine be continuously moved during operation. A path of forward and back then
over half is also a general sanding pattern.
INITIAL CUT
The purpose of the initial cut is to remove old finish, gross imperfections, and belt/drum sander marks on the
floor surface. Use a course grain abrasive (40-60 grit). For extreme cases use 36 grit abrasive.
FINAL CUTS
The purpose of a finishing cut is to remove the scratches from the initial cut and edger cuts. Use a fine grain
abrasive (80-100 grit).
If the surface remains rough after a finishing cut, it may be necessary to use an even finer grain sandpaper
abrasive or use a screen abrasive. The pad used with the screen can also be used with fine grit sandpaper
to get the desired finish. 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.
NOTE: This machine is used for fine finish sanding. However 36 and 40 grit sand paper can be used for
special applications.
