MSC Floors a designated area for their equipment and materi- als on site in a warehouse so they were able to stage the area and leave everything there. W hat wasn't lucky was the tight fit between the scaffold- ing around the hallways and the walls. "at was a bit of a challenge," Fitchett said succinctly. "You're working with a fast cure product, so you had to take your time to make sure that you had a consistent finish, but at the same time, you had to keep it moving as quickly as you could just so the product didn't set up because you have a limited work time with a fast-cure product." Once on site, the crew covered the floors with plastic before starting with the walls and ceilings. Gravity, after all, is hard to fight! After an average 8-mil (203.2 microns) primer coat of Tennant Coatings Eco-MPE (Multi-Purpose Epoxy), walls that were made out of concrete block, such as in the stairwells, received two coats of the 100 percent solids epoxy with broad- casted decorative ceramic quartz, shot with a hopper gun. ose layers were also applied at an average of 8 mils (203.2 microns) using a ⅜ th -inch (1.0 cm) nap roller. e crew laid the chip flat by spike rolling the materials before locking them down with three coats of clear polyaspartic, called TCU (ick Coat Urethane), at 8‒10 mils (203.2‒254.0 microns) each. at ultraviolet (UV) resistant topcoat doesn't cloud from a high build, which lets the colorful quartz shine through. To the ceilings and walls that were made of drywall, such as in the bathrooms, the crew again applied an epoxy primer layer followed by the broadcast system, this time with broad- casted chips. "We achieved the chip coverage required as we were broadcasting it," Fitchett said. e crew spike rolled the chip to lay flat, and then again that layer was lightly sanded and covered by three coats of the polyaspartic at the same thicknesses as before. After each stage, the crew closed off the area from traffic using tape and signs showing when the other trades could reenter. "We communicated with all the on-site trades just not to enter in those areas," Fitchett said. e crew left the concrete floors until last to avoid any issues with the finish from the coatings above. Wearing Kevlar gloves, the crew started with the open areas with Diamatic grinders and SPE shotblasters and around the edges with Metabo hand grinders. ese were hooked up to Husqvarna S-26 high-efficiency particulate air (HEPA) vacuums, and the goal was to give the concrete a Concrete Surface Profile (CSP) 4‒5 finish. According to Fitchett, the concrete was given to them in good condition. COATINGSPRO EQUIPMENT 2018 11 Not only did crew members have to move quickly with the fast-cure product, but they had to work between the scaffolding and walls. Gravity didn't help with that challenge especially when broadcasting the quartz. All coatings came from Tennant. To drywall and ceilings, those coatings included a primer, one coat of Eco-MPE with broadcast chip, and three topcoats of TCI urethane. Safety gear included eyewear, dust masks, and boots.
