36 NOVEMBER 2015 COATINGSPROMAG.COM the products and also the customer service that comes with the materials. "Te driving force behind our choice of materials is the technical support, onsite availability of the manufacturer representative, and speed of delivery; in other words, what the manufacturer brings to the table. Our Demilec rep, Mike Carston, lives in Portland, Maine, and is always able to come out to our jobsites when we need him," said Tompson. Once the batt insulation was removed from a section of the interior roof, the crew installed Demilec's Heatlok Soy 200 Plus closed-cell spray foam using two spray foam rigs — one Graco HV 2035 sprayer and the slightly smaller Graco E-30 rig. Both rigs were equipped with more than 250 feet (76.2 m) of hose, Graco Fusion guns, and 50,000-watt Cat generators. Demilec's Heatlok Soy 200 Plus spray foam is made of recycled plastic bottles and renewable oils. According to the technical data sheet for the product, Heatlok Soy 200 Plus has an R-value of 7.4 at 1 inch (2.5 cm), a density of two pounds (0.9 kg), and creates a building envelope that provides thermal resis- tance and acts as an air barrier and vapor retarder. According to Nutting, the crew applied the spray foam at an approximate thickness of 6.5 inches (16.5 cm). "Applying the coating at this thickness eliminated the void between the fnished ceiling and the face of the spray foam, and it also eliminated the need for the installation of a fre sprinkler system," said Nutting. W hile applying the spray foam, the primary safety concern was respiratory protection for the Standard Waterproofng employees. "We outftted our spray foam installers with full-face respiratory protection using A llegro air pumps. We also had fans running and were able to open some doors," said Tompson. Te crew also wore Ty vek protective suits, steel-toed boots, hard hats, gloves, spray socks (head and neck protection from overspray), and face shields or masks (for the application of the intumescent coating). Once a section had the spray foam insulation in place, the next step was to apply the Demilec Blazelok TBX intumescent coating on top. Te crew used a Graco Texspray Mark IV Pro electric airless sprayer. Te coating was applied at a wet mil thickness of approximately 17 mils (431.8 microns) and a dry flm thickness of approximately 14 mils (355.6 microns). "We applied it in one coat and checked the thickness with a wet mil gage. Te Blazelok TBX material is designed to starve a fre by keeping oxygen from reaching the spray foam insulation. Blazelok TBX is a non-toxic, drain-safe, non-fuming coating that is sprayed directly over the Heatlok Soy 200 Plus spray foam," said Tompson. At Great Heights For all aspects of the job, the crew was working at heights between 20 and 40 feet (6.1–12.2 m) on scissor lifts. Tese particular scissor lifts are small units, designed for interior applications, and they are powered by electricity. Te crew used a combination Standard Waterproofng-owned scissor lifts and Accessing the ceiling area meant working on scissor lifts for the entirety of the job. It also meant wearing proper safety gear, including Tyvek suits, steel-toed boots, gloves, hard hats, face shields, and spray socks. The crew finished the system by spray-applying Demilec's Blazelok TBX intumescent coating at an approximate wet mil thickness of 17 mils (431.8 microns) using a Graco Texspray Mark IV Pro electric airless sprayer.
