SELECTING SANDING BELTS
Selecting the correct size and type of sanding belt is an
important step in achieving a high quality sanded finish. Alu-
minum oxide, silicon carbide, and other synthetic abrasives
are best for power sanding.
In general, when sanding, coarse grit removes the most ma-
terial 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.
