HIGH-TECH COATINGS CONTROL BRIDGE CORROSION

This article describes re-coating work being performed to paint and control bridge corrosion on the 4.3 mile-long William Preston Lane, Jr Memorial Bridge (the Bay Bridge) spanning the Chesapeake Bay in Maryland. The re-coating involves a 2-step process: first, removal of the original, 47-year-old paint coating must be completed, followed by application of a 3-coat, coating system consisting of a prime coat of Zinc Clad IV organic zinc-rich epoxy primer, an intermediate coat of re-coatable epoxy primer, and a finish coat of Acrolon acrylic polyurethane. Methods and techniques used to perform this sophisticated and demanding work are explained in some detail.
