This specification covers procedures for the painting of steel surfaces. The scope of this specification is rather broad, covering both specific as well as general requirements for the application of paint. This specification does not provide detailed descriptions of surface preparation, pretreatments, or selection of primers and finish coats. This specification does provide detailed coverage 01 the procedures and methods for application after the selection 01 the coating materials has been made
This specification for shop, field , and maintenance painting is intended to be used for steel which, because of its exposure condition, will be subjected to corrosive attack, either from the weather or from the service environment, and where a high quality of cleaning and painting is essential. It is not contemplated that the requirements of this speci1ication are necessary for the cleaning and painting of steel which will not be subjected to corrosive attack.
