There have been specifications written for the use of dehumidification during surface preparation and coatings since the early nineties. These early specs keyed in on parameters that were believed to get the job done and reflected the limited knowledge and experience of a very new industry. Since then, dehumidification has become much more widely accepted and specifications exist for pipes, above ground storage tanks, ships and containments.

This paper details some of the aspects of these specifications that have caused trouble for the owner, the specifier and the contractor for various reasons. The technical and economic impact is discussed as well as possible solutions.

Learning Objectives

  • How specs regarding dehumidification during surface preparation and coatings molded current industry acceptance

  • Trouble in specs that can cause issues for various people on the job.

  • Potential solutions to issues caused by specs
