SELECTING SANDING BELTS
Selecting the correct size and type of sanding belt is an
important step in achieving a high quality sanded finish.
Aluminum oxide, silicon carbide, and other synthetic
abrasives are best 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.
