COATINGSPRO SEPTEMBER 2016 45 formal title for FlorLine is operations manager. He led a crew of six to seven people hailing from Ohio. And much like some basketball team strategies, each member had a specific role. ere was a guy who mixed the coatings, two guys dedicated to hand rolling on the 4-inch-tall (10.2 cm) coving, two guys to push roll the floors, and McCoy, who helped trowel and oversee the project. ere was no ball hogging on this court! McCoy was also sure to keep constant communication with his crew throughout the job, which lasted a total of about two weeks. He relied on toolbox talks and cell phones to get the play-by-play from his crew members. at was important, especially considering the approximately 3,300-square-foot (306.6 m²) project, with 1,500 linear feet (457.2 m) on the base, was spread out in nine rooms over four floors. From the first to the fourth floor, the locker room shower areas needed to be covered. "Before we started every morning, I kinda told everybody, 'Here's where you're going, here's what you're doing, I' ll commu- nicate with you in a few hours,'" McCoy said. "We have the meeting first thing in the morning to make sure everybody went where they needed to go. If there were issues, they called me or I called them." e cell phones worked. Part of the success of the communication between McCoy and his crew could be attributed to trust. McCoy has worked for FlorLine for 30+ years, and many of the guys on this project have been there for at least 10 years, according to him. "Everybody kinda knows what's expected of them; I didn't have any new trainees on this job," he explained. Four-Point Play e installation, although located up and down the three flights of stairs, covered the same process despite each room's location: primer, basecoat with chips, and two seal coats. Wearing hard hats, goggles, gloves, and bright orange shirts to make the crew members highly visible to other trades, they started by re-pitching the newly poured concrete floors. The first step for the 6- to 7-person FlorLine coatings crew was to prepare the new, 3,300 square-foot (306.6 m²) concrete surfaces. They used hand grinders from DeWalt to profile the surface.
