60 NOVEMBER 2018 COATINGSPROMAG.COM Getting "Raspy" Because the building is surrounded by a bustling downtown area and towers over nearby Lake Eola, containment was a real concern for the coatings crew on this job. at was especially true when prepping the insulation's surface, which required the use of rasping. Rasping, or scratching, is used to ensure that all surfaces of the foam boards are level; any uneven areas, such as around joints, needed to be removed before the •nishing materials could be applied. Rasping requires the use of •at metal boards that have "pointy teeth," according to Moreno. e EWI crew used two types of raspers on this project: a larger rasper attached to a Ridgid shop vac, which they used to level the wall, and then a smaller one, which they used for detail work. (ey're hoping to patent the larger one to have it sold sometime soon.) As you might imagine, rasping foam can create quite a mess. It creates what Moreno calls foam beads — something that the city did not want •ying around their streets. To mitigate a foam blizzard, the EWI crew used screens on the mast climbers and street-level team members to vacuum up anything that slipped through the cracks. "at was an expen- sive part of the area," Moreno explained. Luckily, the screen didn't create more heat for the crew up top. Actually, accord- ing to Moreno, it oŒered a bit of shade. Besides breaks in the morning and lunchtime, lots of water, and working in shaded areas when they could, the crew couldn't do much else for the heat. For the basecoat, though, they could do a lot for that, including embed it with •berglass mesh. e mud-like BTS Plus basecoat was applied and embedded with the mesh to achieve a total combined average thickness of ⅛ inch (0.3 cm). A very old and recognizable technology called hawk and trowel was used to apply the base and •nish coats. e applicator would hold in his or her non-dominant hand the tray-like hawk that held the cement-like material while the dominant hand held the trowel. A Fine Finish Everyone on the job returned to one detail over and over again: e project had to be completed in the middle of downtown Orlando. Obviously that wasn't news to the GC, material manufacturer, or contractor, but the fact that the •nishing team was able to complete the job successfully in the middle of the urban movement at all, let alone considering the other jobsite challenges, was certainly a feat. To get their materials and equipment to the jobsite on the city square, the EWI crew shared the use of a small entry point through the GC, which handled that schedule. Additionally, once they started working at taller heights, to get their materials up, they used the crane to hoist everything to their makeshift stage in the pool area on the 7š› •oor. "Because of being downtown, it was a big challenge to deal with bringing up materials," Moreno explained. Access was tight in the downtown area, and the crew had to share lifts and cranes with other trades. But after 7 months, they were ready to head home. Working at heights, the crew wore fall protection 100 percent of the time. They also staged equipment and materials on the 7 th floor when working at higher levels.
