48 SEPTEMBER 2018 COATINGSPROMAG.COM Soak Up the Sun e specified coating system from Sika consisted of two primer coats, a thick polyurea, and two acrylic polyurethane topcoats. W hile polyurea is often suitable for wet environments, Osborn said exposure to ultraviolet (UV) rays from the Florida sun required a multi-pronged approach. "Polyurea can handle movements, and it gives you a tenacious bond to a properly prepared and primed substrate," Osborn explained. "is was an aromatic polyurea, so it wasn't ideal for UV exposure, but that's why they put the topcoat on it." e selected topcoat is used primarily on steel bridges, Osborn noted, because of its UV stability and ability to handle outdoor elements. ose qualities also made it a good choice for the lagoon — albeit with thicker application and aggregate added in for extra slip resistance. "With the job designed over concrete, we had to be concerned about the moving of concrete at the joints," Osborn said. "We're talking about the Florida sun and the UV effects, and these were going to be immersion conditions. e system had to be very specific and designed for that." e developers were optimistic that polyurea would serve the lagoon well based on similar projects in South Africa and Dubai, United Arab Emirates. e Osborn crew also brought along Dudley J. Primeaux II, owner of Primeaux Associates and renowned polyurea expert, as a quality control consultant. Many years ago, Primeaux initially trained the Osborn crew on polyurea application techniques, so it was a full-circle project. "I've worked with Jim [Osborn] on polyurea since the mid-1990s," said Primeaux, who assisted in inspection work. The manmade lake was being built for residents. It took 13 days and 12 crew members from Osborn Contract Services to complete the 36,000-square-foot (3,344.5 m²) project.
