The author will present on the various generic coatings technologies available for lining concrete and discuss the advantages and disadvantages of each one. Discussion will include epoxy, polyurethane and polyurea technologies. The goal of the presentation will be to provide some guidance to the attendees on when is the right application to select each technology as part of a specification.
With coating and lining of concrete, while it may seem like a simple, novel task, there are always challenges. Even though concrete may be one of the largest construction materials used today, it is a complex structural matrix that can be ever changing even in a single placement. The need for coating concrete to either waterproof, or extend the life of the structure is not new to our industry.
Since the 1980s, fluoropolymer resin technologies have offered the possibility of a quantum improvement in topcoat decorative properties- gloss and color retention- compared to conventional acrylic and polyester resins. Specifiers of both protective and architectural restoration coatings systems have expressed a need for a new SSPC standard for field-applied fluoropolymer topcoats, particularly for bright and saturated colors.
