Abstract
This paper updates “The Paint and Coatings Cost and Selection Guide”(1) on protective coating costing and selection co-authored by G. H. Brevoort and A. H. Roebuck. Beginning with this edition, data collection and publication will be co-authored by G. H. Brevoort and M. F. MeLampy and K. R. Shields.
Designed to assist the coatings engineer or specifier in identifying suitable protective coating systems for specific industrial environments, this paper provides guidelines for calculating approximate installed costs, expected coating life for each identified system, and how to determine the most cost-effective systems. The effect of maintenance sequences on long-term costs and system performance is also reviewed.
New features of this paper include the Paint Removal Multiplier Table showing the approximate impact on cost when removal of paints is required, and the Variation Multiplier Table, giving multipliers to adjust the base coating cost to reflect structure size, height and component(s) type. Information on the use of metallizing is also included. Practical information provides assistance in understanding the economies of job size, as well as comparing maintenance vs. new construction.
Included in the paper will be 1) most commonly used generic systems in typical industrial environments, 2) service life for each, 3) current material costs, and 4) current field and shop painting costs. 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 and how to prepare a Present Value Analysis are also included.
