Sandblasting

Sandblasting is a process by which fine bits of material are propelled at incredible speeds at a surface in order to remove unwanted features or blemishes. The average unit consists of an air compressor, the fine grit material (which can consist of everything from sand to ground coconut shells and corn cobs), and a "gun" through which the material is dispensed.

Where Is It Used?
This form of cleaning comes in handy in a number of applications. If you've got an auto shop or are a weekend wrench warrior, you know that sandblasting is an excellent way to remove rust and other blemishes from metal and other surfaces. It's also very well suited to cleaning masonry surfaces of blemishes and graffiti, including concrete, brick, stone and any number of other surfaces than can stand up to the barrage that this cleaning process brings with it. Of course, finer uses of sandblasting are also popular, and if you're into glass etching or other decorative applications, then you're already aware of the incredible results sandblasting can bring to those pursuits as well.

Can I Do It Myself?
The easy answer here is no. Of course, with the proper training and experience anyone can master the skill of sand blasting, but for your average homeowner, this is a task best left to the professional. The process comes with its share of potential hazards. Besides the danger inherent in grits of sand being shot out of a gun at high pressure, this cleaning method can also cause respiratory problems if the practitioner doesn't take the proper precautions. The fine silica dust that is a consequence of propelling sand and other materials against rough surfaces at high velocities can accumulate in the lungs over time and cause silicosis. That being the case, only perform sandblasting tasks in a ventilated area while wearing protective suits and the proper respiratory equipment.
