Summary


Guide to Maintenance Repainting with Oil Base or Alkyd Painting Systems

Description


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.
