COATINGSPRO JULY 2018 41 apply the polyurea topcoat. e 100 percent solids polyurea with low volatile organic compounds (VOCs), also from Oak Ridge, was OR80SLM (Silver Lining Membrane). e thicknesses were achieved using a Graco GX7 plural component spray gun. Unfortunately for the Foam Tight crew, the rain kept coming. "We had rain issues. W hen it rained, we had to stop working," Betts said. ey covered the roof with "gigantic" tarps to protect the system from the downpour. ey also applied that system in sections — anywhere from 700 square feet (65.0 m²) to 1,000 square feet (92.9 m²) at a time — to ensure they had any of the susceptible materials, such as the SPF, protected with both a waterproof material and the tarps. Afterward, the crew blew any water that accumulated on an impermeable material with backpack blowers and followed that with a mop. ey also feathered the sections together as they went along until the entire roof was coated. After the crew finished installing the waterproofing system, the client gave Foam Tight another job: Install the vegetative roofing on top of the waterproofing system. is project just kept growing! Foam Tight laid down a fabric liner and then installed pedestals, vegetation, and adjustable walkway paths for the final layer. With that, the crew's work was finally complete. Pay Day Between the hurricane, the two installations, and the jigsaw puzzle-type installation, the crew did the deed: ey turned a leaky roof into a waterproofed one. "e client was totally happy," Betts said. "e project came out nice. We learned a lot, as we always do. Every day we work here, we're always learning in this industry. It was very nice to work with PSE&G. ey're very nice people." e hard work paid off tenfold. Not only did the company become a PSE&G-approved vendor/contractor, but the building has achieved Leadership in Energy and Environmental Design (LEED) status, and this project won the crew second place in the Commercial Roofing category for CoatingsPro's second annual Contractor Awards Program.
