Third-party paint inspection contracts provided an immediate, tangible benefit in supplying a qualified, certified coating inspector full-time to a painting project. Inspectors could be rapidly deployed and provided someone to the project with broad experience in painting projects; however, simply providing a third-party contract paint inspector to a project did not always ensure the project was completed properly.
Zinc-rich coatings have long been known to provide excellent corrosion resistance in highly corrosive environments, in general,inorganic zincs for new construction and organic zincs for maintenance. A recent trend has been toward zinc-rich coatings with reduced levels of zinc dust. An SSPC committee formed to revise SSPC Paint 29, Zinc Dust Sacrificial Primer, Performance Based, to reference performance only, removing reference to minimum zinc dust level.
The role of a Coating Inspector has evolved considerably over the past few decades, and the responsibilities have increased over what used to be a rather straightforward job: to verify that surface preparation and coating application meet the project specification requirements. Today there are week-long or multi-week basic and advanced coating inspection courses, specialty courses that are industry-specific (e.g., bridge, nuclear), courses that are substrate-specific (e.g., concrete coatings inspection) and even coating-specific (e.g., inspection of thermal spray coatings).
