This paper is an update to “Expected Service Life and Cost Considerations for Maintenance and New Construction Protective Coating Work” co-authored by J. L. Helsel R. Lanterman and K. Wissmar for NACE Corrosion 2008.Designed to assist the coatings engineer or specifier in identifying candidate protective coating systems for specific industrial environments this paper provides: 1) commonly used generic coating systems in typical service environments 2) service life for each 3) current material costs 4) current field and shop painting costs and 5) guidelines for calculating approximate installed costs of the systems. Guidelines for developing long-term life-cycle costs and number of paintings for the expected life of the structure are included. The basic elements of economic analysis and justification are addressed together with guidance on the preparation of a Present Value Analysis. Worksheets and examples are provided to aid the reader in the proper use of the information.Updates to the paper include new coating systems for atmospheric exposure and immersion service.
Key words: protective coatings, life-cycle costs, coating selection, coating system life, containment costs, industrial maintenance, maintenance painting costs, industrial environments, corrosive, solventfree, metallizing, galvanizing, Present Value Analysis, installed coating costs.
