HOW OFTEN IS THE GOLDEN GATE BRIDGE PAINTED?
Many misconceptions exist about how often the Bridge is painted. Some say once every seven years, others say from end-to-end each year. Actually, the Bridge was painted when it was originally built. Until 1965, only touch up was required. In 1965, advancing corrosion sparked a program to remove the original lead-based paint (which was 68% red lead paste in a linseed oil carrier). The removal continued to 1995. In 1965, the original paint was replaced with an inorganic zinc silicate primer and acrylic emulsion topcoat. In the 1980s, this paint system was replaced by a water-borne inorganic zinc primer and an acrylic topcoat. The Bridge will continue to require routine touch up painting on an on-going basis.
