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 is used to propel the blasting material.

There are several variants of the process, using various materials, some are highly abrasive and some milder.  We use a moderately abrasive variant, glass with sand.
