Sanding Cuts and Sandpaper

Initial Cut
The purpose of the initial cut is to remove old fi nish and
gross imperfections on the fl oor surface. The sanding equip-
ment should be adjusted to heavy sanding pressure setting
and a coarse abrasive belt should be used. If the surface
is severely damaged by deep scratches, preexisting dwell
marks, uneven planks, etc., it may be necessary to sand
across or diagonally to the grain to restore evenness to the
surface. If these conditions are not present, the initial cut
should be done in the direction of the grain.
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.
Grain Use
16 grit For removing gross imperfections and restore evenness
to old fl ooring. To remove build-up of paints and varnishes.
36 grit For fi rst sanding of new fl ooring (maple, oak). For removing
minor imperfections and fi nishes from old fl ooring.
40 grit For fi rst sanding of new fl ooring (oak, walnut). For removing
minor imperfections and fi nishes from old fl ooring.
50 grit For fi rst sanding of new fl ooring (cedar, pine, fi r)
For cleanup of 16 grit.
60 grit For cleanup from initial cut 36 - 40 grit.
80 grit For fi nal sanding of certain hardwoods. For cleanup
of initial cuts (50 grit).
100 grit For fi nal sanding of certain hardwoods where a smooth
surface is desired.
120 grit For fi nal sanding of certain conifers.
150 grit For fi nal sanding of certain conifers where a smooth
surface is desired.

Final Cuts
The purpose of a fi nishing cut is to remove the scratches
produced during the initial cut. Use a fi ne (60 - 80 grit) grain
abrasive and a reduced sanding pressure setting.
If the surface remains rough after a fi nishing cut, it may be
necessary to use an even fi ner grain of abrasive (80 - 100
grit). Care should be taken in selecting the grit size of the
abrasive. A very fi ne grain will close the pores on a wood
fl oor making admission of a stain diffi cult.
If glazing or burning should occur immediately into a fi nishing
cut, reduce the sanding pressure. If it should occur during a
fi nishing cut, the abrasive has dulled and must be replaced.
