Below is a basic introduction to some of the most
common blasting abrasives. Refer to magazines,
trade articles, professionals, and the abrasive
manufacturer for the specific surfaces that can be
addressed with a type of abrasive. All abrasives
have benefits and drawbacks like quality of sur
-
face finish, abrasive life, toxicity, and what pre-
cautions you must take to prevent environmental
damage or personal injury to your respiratory
system.
Steel Type Abrasives
This aggressive abrasive creates a rough fin-
ish that accepts paint well. The abrasive is very
durable and has a long life, however; it MUST be
kept very dry to prevent rusting.
Alumina Type Abrasives
This multi-purpose abrasive creates a smoother
finish than the steel abrasives, but has a shorter
life span. Less of the workpiece surface is
removed with this more forgiving abrasive.
Glass and Garnet Type Abrasives
Typically this abrasive works well for soft met-
als and addressing surface issues with machine
parts where tolerances cannot be affected. The
life of this abrasive is limited and not well suited
for repetitively recycling.
Sand Type Abrasives
This abrasive is easy to find, and gives an aver-
age finish that is acceptable for most projects.
Sand has a good recycling life and is very eco
-
nomical.
Plastic Type Abrasives
Applied at low pressures of 30 to 50 PSI, plas-
tic abrasives should be harder than the coating
being removed, but softer than the workpiece to
avoid damage. Plastic abrasive is excellent for
addressing surface issues on aluminum, mag
-
nesium, copper, brass, thin steel, titanium, and
composite surfaces and fiberglass.
Other Types of Abrasives Available
Ground walnut or peanut shells.
Ground corn cob.
Sodium bicarbonate.
Wheat starch.
