OPERATION
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 gritwill 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 grituntil
surface is uniform.
