Sandblasting is one of most effective
ways to shape or strip and smooth a surface of any foreign material. It has an effect similar
to that of using sandpaper, but provides a more even finish with no problems with corners, nooks, or crannies. Sandblasting
helps to rejuvenate the material and start the process of making it look new again.
Sandblasting uses compressed air
to "blast" fine sand or other very abrasive, high grit materials through a nozzle and at the object desired to be
sandblasted. These abrasive materials quickly remove the surface of the object leaving a clean surface.
Over the years, the industry has
developed other materials to use for sandblasting instead of sand. These include steel
grit, steel shot, glass beads, Black Beauty, and powdered abrasives of varied grades. They have even ground nut shells and corncobs for specific applications and all of these materials produce distinct surface finishes.
