Use and Retention of Pre-Construction Primers on Steel In Shipbuilding

This guide provides the specifier and user with information regarding the use of pre-construction primers (PCPs) on structural steel in shipbuilding. It provides background on the reasons to use and retain PCPs, the types of PCPs and their application and inspection, and the secondary surface preparation processes that are used when PCPs are retained in the final, compatible primary coating system. While this document contains details specific to the shipbuilding industry, the technical concepts related to the application and retention of PCP may apply to other industrial applications.
