ABRASIVE SELECTION
The kind of abrasive you choose will greatly infl uence the amount of time needed to clean a given
surface area. Abrasive materials include glass beads, aluminum oxide, and others. For best results,
use 80 grit abrasive or fi ner. Do not exceed 80 grit media size.
•
Make sure that the abrasive you use is thoroughly dry. Damp abrasive can cause clogging of
your abrasive blaster.
•
While you may reuse abrasive, remember that abrasive does wear out. After use, abrasive
becomes smoother and rounder, thus reducing abrasive effectiveness.
•
Reusing abrasive may also cause clogging due to debris contained in the mixture from prior use.
