The first process of surface preparation starts with Abrasive Blasting. As per Swedish standard SA 2 ½ (SSPC-SP 10) BS and ISO 8501-1 Abrasive blasting is the operation of forcibly propelling a stream of abrasive materials (sand, grit, quartz, copper slag, shot etc) against a surface under high pressure to remove surface contaminants like rust corrosion, oil, grease, mill scale. Abrasive blasting systems typically include three essential components: an abrasive container (i.e, blasting pot or hopper); a propelling device; and a blasting nozzle or nozzles. The exact equipment used depends to a large extent on the specific application and type(s) of abrasive.
