Protective coating systems provide the primary corrosion protection for assets in sea water. Protective coating systems are defined as a specific combination of surface preparation and coating material applied under specified conditions to a specific structure. Over the past many years, the paint industry has focused considerable resources toward the formulation, performance testing and fine tuning of coatings materials. These efforts have produced outstanding results through implementation of advanced coating materials such as single coat, ultra-high solids paint for tanks, and by sharpening and implementing aggressive requirements in quality assurance and specification documents. Far less emphasis has been placed on understanding and refining the details of surface preparation and the effects of variations in these details on the subsequent performance of sea water immersion coatings. However, it is generally accepted that improper or inadequate surface preparation is a major contributor to real world coatings failures. This area is ripe for coating system quality and performance gains.
