Sandblaster Information
A sandblaster propels pressurized air toward a surface to cause abrasion. People primarily use sandblasting for cleaning rust, paint and dirt off metal or concrete. A sandblaster has a tank to contain the abrasive media. A hose and nozzle is attached to the tank for aim and control. Does this Spark an idea?

Types
-
The least expensive type is a siphon sandblaster. At its most basic configuration, a siphon model consists of a hose that is attached to a bag of abrasives and a nozzle gun. A step up from that is a pressure pot sandblaster which uses a pot or tank that is pressurized. Pressurized sandblasters use less air and have greater blasting strength for quicker abrasion.
Technique
-
Using a sandblaster at too high of a pressure can damage the target item, and some media will abrade faster than others. Using the wrong type of media for the job isn't advisable.

Media
-
A multitude of blasting media (also known as grit) are available to handle a variety of jobs. For maximum abrasion of non-delicate surfaces, some choices include crushed glass, aluminum oxide, silicon carbide and steel grit. For abrasion of more delicate surfaces, there is pumice, plastic, corn cob and walnut shells.
