This technical report provides information on the design, installation, and maintenance of protective polymer flooring systems that are applied and directly bonded to concrete. This document does not detail protective polymer flooring systems installed and bonded to other substrates. Installation of polymer coating systems to exterior applications and special service conditions, such as parking decks, balconies, and swimming pool decks, requires additional consideration with respect to the concrete composition and environmental conditions. These application areas are not specifically addressed in this report. This report is intended for use by manufacturers, specifiers, applicators, and facility owners who specify protective polymer flooring systems for concrete.
