Grit blasting is a surface preparation technique that involves propelling abrasive particles against a surface at high speeds to create a roughened texture 1234. It is used to prepare a surface in readiness for Non-Destructive Testing (NDT) and evaluation, as well as for creating a surface suitable to receive a protective coating or lining 51. Grit blasting is an extremely effective method of preparing plant, tanks, vessels, pipework, and components for NDT and for creating a surface suitable to receive a protective coating or lining 5. The process involves abrading the surface of a target object with a high-speed stream of abrasive particles, removing dirt and rust, and imparting a texture to the surface if required.
