Completed in 1975, the Mercedes-Benz Superdome in New Orleans has been described as the world's largest fixed domed structure (measuring the interior floor area). Although the superdome is designed to withstand 200-mph winds, in August 2005, Hurricane Katrina's 145-mph winds blew away two sections of the roof.
In 2006, Brazos Urethane Inc., Texas City, Texas, repaired the 9.6-acre superdome steel deck and installed a new spray polyurethane foam roof system. However, maintaining the dome's white appearance over time was a challenge.
In 2014, eight test patches of coatings were applied and allowed to weather for 10 months. Quest Construction Products LLC's KYMAX® fluoropolymer was selected, and Brazos Urethane spray-applied the coating. The highly reflective surface will help lower the superdome's roof temperature and provide energy savings.
