F ROOF SILICONE F or one week each July, the Kentucky Speedway is filled with race cars and National Association for Stock Car Auto Racing (NASC AR) enthusiasts. e Kentucky Speedway is home to Quaker State 400, recognized as one of the best races on the Monster Energy NASC AR Cup Series. Built in 1998, the track itself is a 1.5-mile (2.4 km) asphalt racing surface. e spectator area consists of 87,000 grandstand seats, 32 luxury suites, several private club seating areas, and 11 terrace boxes. Needless to say, the owners of the speedway want to make sure the event facility is in tip-top shape for the annual race and related events. According to Quin Heisler, project manager at Spray-Tec Inc., each year the race track gets a makeover, including a new coat of paint. Last year, though, the roof above the suites needed a complete overhaul. "is roof surface is where the television camera crews are stationed for the Quaker State 400. It was in really bad shape. e old EPDM [ethylene propylene diene terpolymer] roof that had been coated with polyurea several years earlier was failing. e polyurea was peeling and had deteriorated to a point in some areas where the EPDM was exposed and leaking. It seemed that the polyurea was applied very thinly, and the UV [ultraviolet] exposure was eating away at the material," explained Heisler. e Spray-Tec team was tasked with inspecting the 30,000-square-foot (2,787.1 m²) roof area, finding the locations where the insulation board below the EPDM was saturated, removing and repairing those areas, and then priming and coating the entire roof with Gaco Western silicone coatings. And the crew had only 25 days before race festivities started! Luckily, the Spray-Tec team was up to the challenge, even with the sweltering heat, high winds, and an extremely tight timeline. Tear It Out e first step in the process was identifying the wet areas that needed to be torn out and replaced. e crew performed an infrared scan on the entire roof. "We went up there right at dusk, after the sun had heated the roof all day. At that time of At the Kentucky Speedway, a roof where camera crews are stationed for the races was leaking. To fix the problem, two 4- to 6-person crews from Spray-Tec Inc. came in to rehabilitate the surfaces. Because the project needed to be completed before the Quaker State 400 race, the crew had limited time to complete the rehab. They took 25 days to recoat 30,000 square feet (2,787.1 m2).
