Reconstruction and rehabilitation of our nation's bridges is a constant concern because of the time and labor involved. Repainting typically involves the application of a three-coat paint system and considerable traffic congestion around the worksite. But the Connecticut Department of Transportation recently heard of a proven, quality solution that would eliminate many of these problems, and put them on the road to significant cost savings. Brian Castler, bureau chief, Connecticut DOT, Bureau of Finance and Administration, investigated this two-coat paint system for new and existing steel bridges that have been blast-cleaned to bare metal. The two-coat system is manufactured by the Sherwin-Williams Co. using polyaspartic coating technology from Bayer MaterialScience. The primer, Corothane I Galvapak, is a VOC-compliant, moisture-curing ure-thane zinc rich primer designed for low temperature application to 20°F. The topcoat, Fast Clad Urethane, is a fast-dry, single-coat polyaspartic specifically formulated for accelerated maintenance painting.
