setting (towards A).
SELECTING SANDING DISCS
Selecting the correct size grit and type of 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 power sanding.
In general, when sanding, coarse grit removes the most
material and fine grit produces the best finish. The
condition of the surface to be sanded determines which
grit will do the best job. If the surface is rough, start with
a coarse grit and sand until the surface is uniform. Then
use medium grit to remove scratches left by the coarser
grit. Finally, use finer grit for finishing the surface. Always
continue sanding with each grit until the surface is
uniform.
