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.
