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.
- BRICKWORK AND STONEWORK – General cleaning and paint removal. Precautions have to be adhered to due to the make up to the underlying substrate. In a dust sensitive area or the necessity to keep the dust levels down whilst cleaning brickwork, stone or concrete, we can connect a water injector into the grit / air flow in order to keep the dust levels down.
- CONCRETE – General cleaning, Paint / Graffiti removal and exposure of the aggregate. Either for aesthetics or adhesion.

- STEELWORK – Removal of old paint and rust to a standard of Sa2.5. (Clean grey metal) ready for re-painting. Note – a primer has to be applied to the cleaned Metal
