This paper challenges the current industry practice of specifying very low levels of residual soluble salts prior to permitting coating application.The paper provides case studies of successful coating applications to surfaces with much higher levels that are currently being specified followed by an analysis of how soluble salts actually impact coating performance.The paper evaluates the industry thresholds of soluble salt concentrations at which is commonly believe salts begin to have a detrimental effect on coatings performance. The analysis is done taking in consideration different factors such as type of service coating type and surface preparation.The paper reviews historical practices and the evolution of current practices in the light of the science (or lack thereof) to support these practices.A cost/benefit analysis demonstrates the need for a more practical approach than industry has been led to believe.
