SANDING DISC SELECTION
Selecting the correct size grit and type sanding disc 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 use the proper grit sanding disc, and not extra
pressure when sanding. Continue sanding with each
grit until surface is uniform,
