DIY Shot Blasting

    • 1). Remove all objects near your work site that are at risk of being sprayed with stray media. Cover immovable surfaces with a tarp and ventilate the area if the target is indoors.

    • 2). Wear a painter's coverall and safety eyewear for full protection. Otherwise, use attire that does not leave any part of your body exposed, including your head.

    • 3). Shut off the valves on the air compressor if they aren't already. Pour a bag of your choice media into the blaster's tank; the most common granule for multipurpose projects is silica sand, but ground nut shells, beaded glass and even metallic shards are available from home improvement retailers.

    • 4). Start the compressor according to the product label or instruction manual that came with the unit. Allow it to pressurize to at least 40 PSI before beginning.

    • 5). Adjust the air pressure to a low setting. Point the nozzle at the affected surface, holding it at least eight inches from yourself.

    • 6). Squeeze the trigger on the blaster and begin cleaning the surface top to bottom. Leave a steady stream on areas that require extra attention, but release the trigger immediately after it is cleaned. Only increase the air pressure if absolutely necessary to dissolve stubborn residue.
