Choosing the Right Blast Media for Abrasive Blasting
A fine abrasive will give you more impacts per volume. The more particles in the stream, the more work is accomplished in the same time. When blasting concrete or wood, you dont need a hard, expensive abrasive, or a coarse particle: crushed glass makes an excellent, inexpensive choice for work on relatively soft surfaces.
