Appreciation of Florida’s Emerald Coast reached new heights when a 500,000-gallon pedestal water tank on Okaloosa Island was refurbished with a mural representing the area’s Appalachian quartz sand beaches and featuring an advanced fluoropolymer coating system from Tnemec.
The tank’s exterior base coating system was applied by Ohio-based American Suncraft Construction Company and mural artist, Eric Henn, with engineering services provided by Polyengineering, Inc. of Shalimar, Florida.
Exterior steel was prepared in accordance with SSPC-SP 2 Hand Tool Cleaning and SPC-SP3 Power Tool Cleaning and primed with Series 135 Chembuild, a modified polyamidoamine epoxy for marginally prepared steel and tightly adhering old coatings. Series 73 Endura-Shield, an aliphatic acrylic polyurethane, was the intermediate coat, followed by a finish coat of Series 700 HydroFlon, an advanced fluoropolymer that offers outstanding resistance to UV light for unprecedented long-term gloss and color retention. The project did not require replacement of the existing Tnemec coating system on the tank’s interior, which was in sound condition.
HydroFlon was also used for the lettering and the mural, which required 14 different colors ranging from white, to different shades of blues and greens. Nearly 150 gallons of the exterior coatings were required to complete the project, which was voted Tnemec’s 2012 Tank of the Year based on its aesthetic, creative and innovative uses of a coating system. The project was selected from more than 200 tanks that were nominated for the contest.
