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.
