  • Abstract:
    The accelerated bridge paint (AB-Paint) program evaluated a new Sherwin-Williams two-coat, fast-curing paint system. The system is comprised of an organic zinc-rich primer (SW Corothane I Galvapac One-Pack Zinc-Rich Primer B65 G11) and a polyurea-modified high-build urethane finish coat (SW Fast Clad Urethane B65950 Series). The two-coat system would be a replacement or alternative for the current three-coat paint system (i.e., zinc-rich primer/epoxy intermediate/ urethane finish) approved in Bulletin 15. The accelerated bridge painting technology could provide a material cost benefit by applying only two coats instead of three. There was the potential that the blasting, primer and topcoat could be placed during a work shift, which would result in reduced labor cost. There would also be benefit to the traveling public with shorter traffic interruption and inconvenience with the accelerated technology.
