and contamination from the rooftop that would have reduced the adhesion and future performance of the Roof Mate coating. Throughout the entire project, Commercial took extra care in making sure they followed all necessary safety precautions. Every roofer was tied off during the entire process, from prepping and cleaning to final coating application, and there were weekly safety meetings from the NRCA Toolbox Talks. The crews utilized DBI-SALA and SafeWaze fall protection and safety equipment that included full-body harnesses, lanyards, 50-foot ½-inch safety rope, self-tracking rope grabs, reusable roof anchors as well as leather and rubber gloves when necessary. The Commercial roofers also wore DeWalt safety glasses and disposable earplugs by E.A.R. to combat the debris and noise resulting from the use of the pressure washers. "Safety is a component of our every- day business practices because when you're working at these heights, there's no such thing as too safe," said Johnson. Once the UCC was rinsed with water from the pressure washers and the roof was dried by the sun, Commercial Roofing began to apply the Roof Mate Basecoat directly to the metal roof surface. The coating was applied at a total thickness of 35 mils utilizing a Graco hydraulic system that included a model GH 733 spray pump, Silver Plus gun and RAC X #635 tip. The pump was connected directly to 55-gallon drums of Roof Mate and sprayed at a ratio of 45:1. The large containers helped acceler- ate the installation, which, according to Johnson, allowed Commercial to apply more than 3,000 square feet of coating per day. They left a 10-foot edge around the rooftop perimeter, and using ½-inch nap rollers, they roller-applied the remainder of the coating to prevent overspray. After the Roof Mate was applied to the entire rooftop, the roofers began the Acryclad application. As with the Roof Mate, Commercial sprayed the Acryclad onto the roof with hydraulic spray equip- ment directly from 55-gallon drums. Since Acryclad was used primarily for aesthet- ics, Commercial Roofing applied it at a thickness of four mils, enough to provide uniform, long-term color, and add an appealing sheen and shimmer to the roof. However, a pleasing appearance was not the only reason that Acryclad was an ideal choice for this project. RESORT FRIENDLY ROOFING SCHEDULE "This project was extremely delicate due to the customer-focused nature of the resort industry," said Johnson. "As you can imagine, atmosphere is everything at a place like Port Royal, and resort officials made it very clear that this re-roofing project could not disrupt the guests or disturb their stay." Johnson did note that it was impossible to remain invisible to the guests, but he said his crew did their best to stay out of the Write in Reader Inquiry #197 January 2009 J 45
