Sandblasting is the process of using compressed air to propel abrasive media at a surface to clean, (usually paint & rust),debur, or to prepare a surface for a coating of some sort. There are two kinds of sandblasters: âSuctionâ / âSiphonââ & âPressureâ Blast Systems.
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.
