Thin Film Concrete Coatings
Kentucky Transportation Center (KTC) researchers obtained eight types of concrete coatings to assess their performance and resistance to chloride penetration. Researchers evaluated eight of the systems in the field and seven in the laboratory. In the field, coatings were applied to a bridge pier that had suffered degradation and chloride contamination. This site will undergo long-term monitoring in order to thoroughly evaluate the coating systems. Adhesion of all products in both field and laboratory application was sufficient to provide a durable coating, and ranged from approximately 500 psi to 1,600 psi. Researchers also tested color and gloss changes, which are early indicators of coating degradation. Although performance varied, one system (System 8) was by far the least effective. Three two-coat systems performed significantly better than the other five at retarding chloride transmission. Those coating systems use epoxy primers with polyurethane top coats.
