Sandblasters: 5 Fast Facts

Fact #1. A soldier and inventor patented the first sandblasting machine in 1870. This was after he saw the effects of wind-blown sand and corrosion on both windows and rocks. He used quartz within sand as his corrosive element of choice for the machine. This was along with a jet of steam, air, and water.
Fact #2. New types of blast media were identified by the late 1930s. This was a response to the growing concern over high-risk exposure to silica dust and potentially fatal silicosis. Since that time, sandblaster versatility, safety, and durability have been refined to accommodate a variety of job types for both domestic and professional use.
Fact #3. If you're planning to renovate your home or prepare a component for a new coat of paint, a sandblaster is the perfect abrasive solution. It's a compressed air tool designed to propel pressurized silica sand toward the surface of various objects. This is done at a high velocity. It grinds surfaces down to a smooth finish and can clear away debris, rust, and other contaminants.
Fact #4. The model one chooses to invest in depends on the location and requirements of the job. For example, if you anticipate sandblasting surfaces in tight corners and hard-to-reach places, a siphon option is a good solution. There won't be a bulky container above the gun to get in your way while you work. Also, consider hose length. The container should be 10 or more feet away from your workspace when sandblasting corners and tight spots.
Fact #5. Safety is a major consideration when working around potentially harmful airborne contaminants. If constant use of a sandblaster is part of your trade, you should minimize the risk of unhealthy exposure. Outfit yourself with protective clothing and other equipment, such as a respirator.
