5 above To compensate for faster cure times brought on by higher ambient temperatures, the crew mixed smaller batch sizes. But the coatings' quicker sets also helped the crew make up for lost time. The Nash crew installed the topcoat on a Friday, brought the striping crew in on Monday, and had the parking structure open to traffic on Tuesday. is designed for use in Southern California to meet the region's low volatile organic compound (VOC) requirements. These requirements are set forth and regulated by the South Coast Air Quality Management District (SCAQMD), which encompasses most of Los Angeles, San Bernardino, Riverside, and all of Orange counties. The SCAQMD regulates all sources of stationary air pollution for the aforementioned regions. The crew poured and rolled the Poly-I-Gard 246SC at a thickness of approximately 10 mils (254 microns), DFT. Nash credits the Polycoat materials for performing incredibly well under such unusual circumstances. "I was a little worried about gassing because of the high temperatures," Nash says. "It wasn't a problem with the Polycoat Products coatings. There were no bubbles and no gassing." Nash did, however, make some adjustments. Both the Polyprime U and the Poly-I-Gard 246SC are sensitive to heat, so Nash was very careful with batch sizes, especially the primer. "I mixed the two-part Polyprime U primer in half batches—we mixed two-and-a-half gallons, sometimes less, at a time instead of the usual five gallons," Nash says. no Day at tHe BeaCH! Working feverishly, the Nash Deck crew broadcast Cemex-brand Lapis Lustre 2/16 sand onto the wet coating. "We needed to have a fairly aggressive non-skid component added to the coating system," says Nash. In the highest traffic areas, there was a double broadcast, ensuring excellent non-skid properties. Two final coats of 10 mils (254 microns), DFT, of Poly-I-Gard 246SC were then laid down on the entire deck area. In the areas of highest vehicular traffic, the coating system has a thickness of over 40 mils (1,016 microns) that protects the existing urethane base coat and underlying concrete substrate. The non-skid component of the system ensures that cars and pedestrians do not slip and slide in wet conditions. According to Nash, the job went off without a hitch, even with 44 CoatingsPro g January 2013 the unseasonably hot temperatures, allowing him and his crew to complete the project right on schedule. "We finished on Friday and the stripers came in on Monday," Nash says. "The roof deck of the parking structure was open to pedestrians and vehicles on Tuesday." Throughout the project, Nash and his crew followed all standard safety procedures. "We wore gloves and safety glasses, and during the prep work, wore dust masks," says Nash. There was no need for fall protection at any time during the job since all railings were up to code. There were no other trades doing work and no heavy equipment on the roof deck, Nash says. Another factor that made the job run smoothly for the crew was the absence of ducts on the roof deck. "If there are ducts and intakes that can suck fumes into the building, it is always a big concern and something that needs to be considered before any work can be done," Nash says. Fortunately, since there were no ventilation intakes on the roof of the parking structure, there was one less step in the process. tHey Beat tHe Heat Nash Deck Coating and Polycoat Products made a great team on this parking structure roof. Polycoat's van der Capellen is extremely happy with the outcome of the job. "When we were contacted about peeling and flaking coating on the old roof deck, we knew our products could take care of the problem," says van der Capellen. "It had only been a year and a half since the old deck had been recoated, and it was already failing. Now, the client has a coating system that will last." Nash is quick to point out that he is impressed with the coatings and his crew. "I've been doing this a long time – 25 years – and I am really happy with the way the Poly-I-Gard 246SC performs," says Nash. Although this was Nash Deck Coatings' first job for Saddleback Memorial Medical Center, with the way his crew beat the heat to recoat and reopen the parking structure, Nash bets it will not be the last!
