Abrasive blasting is an mechanical operation of cleaning or preparing a surface by forcibly propelling a stream of abrasive material on the surface using a compressed gas (typically air) or pressurized liquid (typically water) as a propellant. Abrasive grains used for the blasting operation ranges from coarse grits to micron sized particle depending upon the operation and desired results. 

 

Blasting Media, or abrasive grit, is used to clean and prepare surfaces prior to applying coatings or to produce a desired surface profile. Grit blasting is an essential part in preparing a surface for finishing because the performance of the final coating very much depends on how well the surface was prepared. Blasting media, such as aluminum oxide, is an abrasive grit that is blasted through a wet or dry pressure blasting system. The process of abrasive blasting, or grit blasting, removes the containments and unwanted substances from the piece’s surface in order to produce a clean surface that will promote adhesion to the final coating. Washington Mills abrasive blasting grain is highly effective on many surfaces including: metals, glass, ceramics, marble, granite and other stone.
