DRY GRIT BLASTING
Grit Blasting or Sand Blasting as it sometimes known as, is a form of cleaning using high pressure air from a compressor and an angular grit (sizes vary from ultra fine to course), being forced down a Blast Hose and out of a nozzle directed at the article being cleaned.
This is when the experience of the operator comes into operation as the air pressures and the grit size needed are correct; otherwise damage can be caused to the article or the underlying substrate being cleaned.
