54 JANUARY 2018 COATINGSPROMAG.COM this dealership a 20-year warranty. Remember, this roof had been leaking for 17 years!" Before starting preparation work, Cleavenger made sure to utilize the proper personal protective equipment (PPE) each day to make sure he was safe atop the roof. Using materials from Leading Edge Safety, PPE items for Cleavenger and his crew included safety glasses, neoprene rubber gloves, non-slip rubber boots, and the use of harnesses and lanyards at all times, with seam clamps used to secure tie-off positions. After mobilizing, installing the proper PPE, and bringing equipment to the roof, he quickly got to work using a 17-inch (43.2 cm) Triple S rotary polisher to sand both the roof and the canopies. "I stuck this mechanical floor polisher between the seams and went up and down the barrel roof with it," Cleavenger said. "I used an abrasive pad and literally mechanically sanded this entire roof. Once we sanded the whole roof, I also used a small 8-inch [20.3 cm] battery powered scrubber for the tight spaces and edges. It took about four days to sand that roof, but it was a big part of the job because I wanted to give the silicone excellent adhesion." e metal was then pressure washed with a concentrated roof cleaner and water using a 4,200-psi (29.0 MPa) pressure washer from DeWalt. Cleavenger finished the preparation process by filling in all closures with closed-cell foam and coating them with the GE Enduris Seam Sealant. A ll laps and transition points were covered with the sealant and GE's clear SCM 2002 silicone caulking using an electric caulking gun, and no fabric reinforce- ment was needed. New Apparatus Boosts Application With surfaces prepared and sealed, crew reinforcements from Freedom Coatings arrived just in time for the second week of the project! e job specification called for the seams to be sprayed Sur face prep included more than the usual pressure wa shing seen on roof tops. The metal was also sanded mechanically with a rotar y polisher and a scrubber (for smaller spaces). The metal seams could have caused a setback, but Freedom came up with an experimental apparatus with the manufacturer. It held the spray gun so that both sides of the seam could be coated simultaneously (not shown). "Every contractor needs to understand the importance of good surface prep," said Cleavenger, who manned the surface prep machine to ensure success. Along with caulking and foam, the leaks were tackled. Roof Restoration VENDOR TEAM DeWalt Equipment manufacturer 701 E Joppa Rd. Baltimore, MD 21286 (800) 433-9258 www.dewalt.com Everest Systems Co.
