This Guide covers the steps necessary for the repainting of steel structures previously painted with oil base, alkyd, or other conventional oleoresinous paint systems with the same generic paint system as the existing one.
When special paint systems such as zinc-rich, epoxy, or urethane are involved, spot tests may be necessary and the instructions of the manufacturer should be followed.
The amount of maintenance cleaning and painting is determined by the need for corrosion protection and appearance and should be described in the procurement documents.
This Guide outlines the components of a complete maintenance repainting system. A standard system consists of surface preparation and repainting according to the guidelines presented.
