Pre-construction Primer (PCP) is a zinc-containing, weld-through primer applied at low thickness to minimize rusting of steel during storage and fabrication. PCP removal is perceived to reduce risk of coating failure associated with painting over an aged zinc primer. PCP is retained in many commercial shipbuilding operations in order to reduce costs and provide a better performing coating system. This paper will review commercial industry practices and the guidance provided by marine coating manufacturers.
