The scope of this standard is to set forth guidelines for the selection and installation of liquid organic coatings to be used over properly prepared concrete surfaces exposed to immersion conditions or chemical splash and spillage. The term lining is commonly used to describe a coating used to protect a structural substrate from the contained chemical. For simplicity, in this standard, the term coating (or coating system) is used when referring to any protective system, whether used as a lining, floor surfacer, or a coating.
