50 JANUARY 2019 COATINGSPROMAG.COM wood basketball court, we completely leveled that floor to get the flatness and level where it needed to be before putting the hardwood floor back on top of it." In all, the resinous flooring, polished concrete, overlay, and self-leveling underlayment added up to a total footage of ~150,000 square feet (13,935.5 m2). Initial specifications called for the coatings crew to begin working in January, but delays elsewhere pushed it to April. Nonetheless, the job still had to be finalized by late October since tickets were already sold for the 2018–19 season! e Bearcats had been kicked out of their home to nearby arenas for the prior year, and teams were eager to move back in. us, the crew was aggressive in formulating its game plan. Beating the Buzzer For a job this large, planning was essential. Fifth ird Arena sits in the center of an active, urban campus, so moving equipment and 200+ skids of material in and out during school hours was a challenge. us, Kipp and other Hardig officials were diligent in establishing protocols and precise timetables with UC. "ere had to be a ton of logistics because we were in so many places around the arena," Kipp explained. "Our entire existence in the arena had to be mobile, so we had to be able to move our equipment." W hen transit was required, a custom- printed FloorShell from Triamco with Hardig's logo was used to cover and protect the inside floor. Another priority was safety, since the high-profile project began after the implementation of enhanced silica standards from the U.S. Occupational Safety and Health Administration (OSHA). "is created a sensitive environment for dust control and environmental and safety concerns," Kipp said. "Our OSHA silica plan was a major part of our preparation." Hard hats, safety glasses, high-visibility vests or shirts, steel-toed boots, and cut-resistant gloves were worn at all times as personal protective equipment (PPE). For silica compliance, extra PPE included wearing 3M's disposable N95 particu- late respirators with dust masks; using dustless shrouds and vacuums; and wearing face shields when grinding or chipping. Each morning, crew members went through stretch and flex exercises and toolbox talks to analyze potential hazards. "Good communication was key because everyone knew their roles," Kipp said. "ey didn't need to be babysat through- out the project." While substrates were both existing and new concrete, each presented unique challenges. "All the existing concrete was extremely rough from the demolition of existing floor treatments," Kipp said. "And the new pour concrete was extremely challenging to polish, due to it being a lightweight mix on a metal deck." Phase one involved applying 30,000 square feet (2,787.1 m2) of resinous flooring. For this, crew members shot blasted existing and new concrete using a Blastrac 1-10D to achieve a Concrete Surface Profile (CSP) 4–6, required to install the Sika Decoflake UEF system with 4 inches (10.2 cm) of integral cove base. "We had to get those floors done first so the mechanical contractors, kitchen equipment personnel, plumbers, and others could come in behind us," Kipp explained. "Everything had the integral [cove] base, and everything had to be completely seamless." For that system, the initial layer was the Sikafloor-22 NA PurCem urethane cement basecoat — applied at approximately 0.25 inch (0.64 cm) using a C AM gage rake from Seymour Midwest — with Sikadur-509 aggregate broadcast to excess. en, the Sikafloor 264 100-percent solids epoxy primer was applied in black at an average of 12 mils (304.8 microns) using an 18-inch (45.7 cm) Midwest Rake squeegee from Seymour Midwest, with a 0.25-inch (0.64 cm) custom flake broadcast to excess. Next, the clear Sikafloor 217 was squeegeed as the grout coat at an average of 16 mils (406.4 microns), while the Sikafloor 510 LPL polyaspartic served as the topcoat at an average of 5 mils (127 microns), with Sika's Barefoot 20 aggregate added for non-skid qualities. Meanwhile, phase two encompassed the application of 35,000 square feet (3,251.6 m2) of self-leveling underlayment Under the basketball court, the crew used a thermal laser to map and achieve proper flatness. Then, they used scarifiers, scalers, and brush hammers before applying the self-leveling underlayment with gage rakes. The crew covered various aspects of safety, including stretch and flex exercise, toolbox talks, and personal protective equipment (PPE). Because of new silica standards, the crew prepped with dustless shrouds and vacuums. Hoops Arena Revamp
