The basics of sandblasting

Equipment and Materials

The basic sandblasting setup consists of three primary pieces of equipment: a blasting pot, an air compressor, and a blasting nozzle. The blasting pot holds the abrasive material and regulates its flow to the nozzle. The air compressor provides the high-pressure air that propels the abrasive material from the nozzle onto the surface. The nozzle directs the stream of abrasive material and comes in various shapes and sizes, each designed for specific types of projects. The choice of abrasive material varies depending on the particular job requirements, with options ranging from traditional sand to more specialized materials like glass beads, steel grit, or walnut shells.
