Overview A New Build bridge required a protective coating system which could offer long-term corrosion protection. Challenge A short time frame of 2 days was given for project completion. Grit blasting was not permissible due to the damage it would cause to the surrounding environment. Full encapsulation would also incur a high cost and would significantly increase the project duration. Solution Above the water line the substrate was high pressure water jetted (500bar). Two coats of wet & rust tolerant epoxy Epo-chemTM RL 500PF was then applied. Below the water line, the substrate was prepared using mechanical methods. This was followed by one primer coat of solvent-free, wet & rust tolerant epoxy Epo-chemTM RS 500P and one topcoat of Chemco’s specialised s
