This SSPC/NACE joint technical committee report presents current information about why and how dehumidification and temperature control are being used to achieve higher-quality coating/lining projects. It discusses methods of dehumidification, sizing equipment, the impact of contaminants and relative humidity, the uses of dehumidification and temperature-control equipment, and inspection instrumentation. An appendix provides information about the relative humidities at which different contaminants can bring moisture to the surface. This technical report is intended for use by engineers, coating consultants, and others who write specifications for coating projects involving tanks or enclosed spaces.
