Abrasive blasting

Abrasive blasting, more commonly known as sandblasting, is the operation of forcibly propelling a stream of abrasive material against a surface under high pressure to smooth a rough surface, roughen a smooth surface, shape a surface or remove surface contaminants.A pressurised fluid, typically compressed air, or a centrifugal wheel is used to propel the blasting material (often called the media).
