Protective coatings are the principle materials used on many industrial structures for corrosion protection. It should be recognized though that all protective coatings have a finite service life, and that independent of how well the coating system was originally applied, coating breakdown will eventually occur. Oftentimes the service life of a protective coating system can be extended by performing maintenance painting once the onset of deterioration takes place, reducing life cycle costs. The aspect to consider in coating selection then should be “time to failure,” not whether the system will fail. Some coating systems fail long before the anticipated service life is over. These are known as premature coating failures. Premature coating failures can be caused by improper surface preparation or coating application procedures, improper coating system selection, improper formulation or poor quality raw materials, or the design of the structure itself. When a premature failure occurs, an investigation can be undertaken to uncover three important discoveries: the cause of the premature coating failure, the party that was responsible for the failure and the level of repair required to ensure corrosion protection and integrity of the facility/structure. The purpose of this webinar is to familiarize the attendees with the natural and artificial factors that accelerate coating deterioration, technical terms associated with degradation and common coating defects that can be avoided and minimized. Participants will be eligible to receive credit from SSPC.

Sarah Olthof, Laboratory Manager

Sarah Olthof is the laboratory manager for GPI and is responsible for all laboratory operations including supervision of the quality program, test method implementation, and project oversight. She is an active member of ASTM, the Bolt Council, SSPC and NACE. Her twenty years of experience encompasses a wide range of testing including analytical chemistry, forensic analysis, physical testing and accelerated weathering for protective coatings and related samples.



CHLOR RID International, Inc. is the world leader in soluble salt information, measuring devices, and decontamination products for surface preparation. A major cause of premature coating failures are remaining surface salts which are not detected or treated prior to coating application. The CHLOR*TEST ‘CSN’ kit accurately and easily detects the presence of residual chloride, sulfate, and nitrate salts on the surface which are prevalent in the water and wastewater processing industry. CHLOR*RID liquid soluble salt remover is recognized as the most effective, easiest, and economical tool for removing surface salts to meet stringent job specifications.
