Abrasive blasting WikipediaSurface Preparation Steel

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 contaminantsA pressurised fluid typically compressed air or a centrifugal wheel is used to propel the blasting material often called the media Surface Preparation Steel Good Surface Preparation is essential if the full potential of high performance epoxy schemes is to be realised Grit blasting is preferable for the preparation of bare steel however disk grinding may be used for the preparation of welds and limited areas where blasting is
