Objective:
Current US Navy practice requires removal of pre-construction primers on all critical-coated surfaces. NSRP has sponsored a number of studies over the past 30 years which have supported retaining pre-construction primers as a cost saving measure without any service life impact. It is estimated that allowing pre-construction primer retention can save the Navy in excess of $7 million per year. This project documented the procedures used to retain pre-construction primer during repair of USS VICKSBURG and during construction of the T-AKE class. In both cases the pre-construction primer is retained on steel in critical coated areas. Past studies and the present work conclusively demonstrate that pre-construction primer can be retained without impacting coating performance.
