The basic system implemented by the Highways Agency consists of degreasing then T Washing, only required if the substrate is new galvanised steel, then applying a zinc phosphate primer, an epoxy build coat followed by a polyurethane top coat in either a semi-gloss of gloss finish. There is a standard film thickness for each coat providing a total film thickness that will offer a life expectancy in excess of 10 years to first maintenance. For a longer lasting system there is a shop applied system based on an epoxy build coat followed by an Engineered Siloxane such as PPG PSX 700 offering a life expectancy of 25 years, this is the Highways Agency Item No.185.
