Shot blasting and priming

The fully automated process produces a surface cleaned to minimum Class 2 1/2 in accordance with AS 1627, Part 4 which is then coated with a preconstruction primer to typical dry film thickness of 20 micrometers.

Preconstruction primers provide protection from atmospheric corrosion for periods of between 6 and 12 months, have minimal effect on gas cutting and welding and are compatible with a wide range of coating systems.

Generic types of preconstruction primer currently applied include inorganic zinc silicate and epoxy. The automated abrasive blast cleaning and priming process provides substantial cost and quality benefits over traditional manual methods of surface treatment.
