SANDING SHEET AND PAD SELECTION
Selecting the correct size grit and type sandpaper is an
extremely important step in achieving a high quality sanded
finish. Aluminum oxide, silicon carbide, and other synthetic
abrasives are best for power sanding. Natural abrasives,
such as flint and garnet, are too soft for economical use in
power sanding.
In general, coarse grit will remove the most material and finer
grit will produce the best finish in all sanding operations. The
condition of the surface to be sanded will determine which
grit will do the job. If the surface is rough, start with a coarse
grit and sand until the surface is uniform. Medium grit may
then be used to remove scratches left by the coarser grit and
finer grit used for finishing of the surface. Always continue
sanding with each grit until surface is uniform.

n Align the pointed tip and rounded edges of the sanding
sheet or pad with the pointed tip and rounded edges of
the hook-and-loop pad. Carefully press the fuzzy side
of the sanding sheet against the pad as tightly as pos-
sible.
NOTE: Sanding sheets can be reused for the life of the sand-
ing abrasive. It is recommended that you keep the sanding
sheet backing pad clean to provide for best adhesion. Clean
occasionally by brushing lightly with a small brush.
