“The project team worked tirelessly on the tank restoration to bring this city landmark back to its rightful state as a welcoming – and now iconic – community billboard,” said Heywood. “The efforts of the en- tire team ensured a successful rehabilitation that will maintain potable water service and superior aesthetics over the long term.” RUNNER-UP: Century-Old Water Tank Stands the Test of Time Operated by NJAW, the more than 110-year-old standpipe serving Had- don Heights Township required restoration inside and outside. Starting in September 2018, coatings contractor Titan Industrial Services, Inc. faced a tight deadline to complete restoration of the 63,000-gallon tank before the frigid New Jersey winter set in. To ensure applicators could apply coatings during the cool, wet fall season, Titan Industrial Services set up a full containment system with dehumidification equipment. In addition, the team specified a variety of Sherwin-Williams coatings with fast-curing and low-temperature application properties that enabled successful applications even as favorable weather conditions diminished. For the tank’s interior lining, applicators applied a primer coat of Sherwin-Williams Macropoxy® 5500LT followed by a high-build coat of Poly-Cote™ 115, a fast- drying lining system from Sherwin-Williams that helped the crew stay on schedule. For the exterior, the crew applied three additional Sherwin-Williams coatings. They first applied a primer coat of Coro- thane® I – GalvaPac 1K zinc primer, which enables low-temperature applications down to 20°F (-7°C), and also features moisture-curing properties. Next, applicators sprayed a full coat of Acrolon™ 218 HS acrylic polyurethane on all exterior surfaces, followed by a complete topcoat of high-gloss Fluorokem™ HS fluoropolymer urethane. HONORABLE MENTION: Cincinnati’s First Water Tower with a Logo Makes History Following the restoration of a 2.5-million-gallon tank serving Cincin- nati’s largest neighborhood, the refreshed 118.5-foot-tall, 105-foot- diameter tank now features colorful striping and the Westwood com- munity name, officially welcoming visitors to the neighborhood. The adornment and logo are a first for Cincinnati, which previously did not have any water tanks with logos within city limits. Coatings applicator UCL blasted and coated the tank’s full exterior, as well as its dry interior spaces. Following blasting, UCL applicators first spray-applied a single coat of Corothane I – GalvaPac 1K zinc primer. For the intermediate coat, UCL applied Sherwin-Williams Macropoxy 646-100 fast cure epoxy – a choice made to help accelerate the project during the cool Fall and early Winter months, enabling sufficient time before the weather turned too cold to apply the urethane topcoat. For the topcoat, the team chose Sherwin-Williams Fluorokem HS, an ultra- durable, ambient-cured, high-solids fluoropolymer urethane finish, for the topcoat. The coating delivers exceptional color and gloss retention and can withstand severe exposures, making it ideal for the tower’s final finish, as well as the blue and gold stripe pattern and Westwood community name adorned on the tower.

hicles from dust and overspray during blasting and coating operations. Starting with the tank’s legs and underside before moving to the top, the SUEZ crew blasted and coated the entire exterior. They first applied primer and stripe coats of Sherwin-Williams Corothane® I – GalvaPac 1K zinc primer. The moisture-curing primer gave the crew flexibility for the applications, enabling applicators to spray the coating even during very humid conditions. Next, the crew applied an intermediate coat of Sherwin-Williams Acrolon™ 218 HS acrylic polyurethane, a fast-drying coating that delivers excellent color and gloss retention for exterior exposures. For the decorative topcoat application, Jim Kelly, owner of Industrial and Commercial Signs, drew and painted the tank’s intricate, 11-color geometric design on the tower’s top, underside, legs and riser by hand. He also added a slogan touting the “All-American City – Fort Lau- derdale” on four sides of the tank. Kelly and a small crew then rolled and brushed the different colored areas using Sherwin-Williams Fluo- rokem™ HS fluoropolymer urethane. The high-gloss, ultra-durable coating provides unparalleled color and gloss performance, helping the tower maintain excellent long-term aesthetics for its various shades of orange, pink, yellow, gray, white, blue and green. Artist Peter Symons designed the unique pattern.
