How to Choose the Right Sandblasting Media? -
Sandblasting is a process in which sand, glass beads or some other medium is shot at high speed through a machine across the surface of a hard material until it is sanded smooth. Sandblasting is often done to remove a previous finish on an item, to remove rust, or to prepare a surface to receive a new coat of paint. The kind of medium used to blast the surface depends on how difficult the removal is and Glass Beads Vs. Sand Blasting | HunkerSand blasting is achieved by blasting sand on to a metal surface through very high air pressure.
