The materials commonly used for media blasting include salt, sand, glass beads, water, metal, minerals, crushed nuts or fruit, corn, wheat and even dry ice. A blasting machine designed for use with the specific media is also required along with proper safety gear.
Media blasting can be used in a variety of ways such as to remove paint or rust from a vehicle, clean various substances off of surfaces, including graffiti from walls, engraving, and lettering signs and monuments.
Media blasting can be potentially hazardous. Risks include burns caused by contact with the blasting items and potentially toxic dusts created by the blasting materials or the surfaces exposed to media blasting.
