| Résumé : |
Many bridge owners seem to believe that applying all three coats of paint in the shop is more cost-effective and will provide better coating performance on new steel.
This article will discuss the most widely used coating system coming out of the shop for bridge coatings, an inorganic zinc-rich primer, an epoxy intermediate coat and a polyurethane topcoat, and examine the cost differences through two case histories from the Maryland State Highway Administration where all three coats were applied in the shop. |

- FIGURES : 1. Once the bolts were tightened on the surfaces which had all three coats applied, failures occurred with the intermediate and topcoats fracturing down to the primer - 2. Fascia was only touched up and not repainted - 3. Shop cleaning and painting allows for a controlled atmosphere - 4. This figure shows a shipping and erection defect - 5. This gouge goes down to substrate and must be repaired to ensure that the coating has the longevity it was designed for - 6. Applying an additional coat of finish may be necessary to give these fascia defects a uniform appearance after erection is complete
