COATINGSPRO SEPTEMBER 2018 49 "is was not his first rodeo!" Primeaux also helped develop a "mockup" demonstra- tion prior to installation and answered the client's technical questions regarding the material. According to him, the devel- opers wanted to see what the system would look and feel like, along with how it would bond to the concrete. e developers were particularly curious because they were aware of a smaller U.S. "crystal lagoon" project that had encoun- tered problems with a different system. "e coating they had put down was peeling up and not staying in place," Primeaux explained. "But once we showed them what we were going to do [on this project with the bond] and the slip resistance, they were sold." Wet and Wild Safety was an immediate priority for the 12 crew members upon arriving at the jobsite in April 2018. Crew members regularly used personal protective equipment (PPE), such as nitrile gloves, Honey well Safety's Uvex polarized safety glasses, Ty vek protective suits, and boonie (aka bucket) hats w ith a front bib and back-of-neck fabric for protection from sun exposure and heat. Surface prep included Blastrac shot blasters, Blastrac and Pullman Ermator vacuums, dust collectors, and Metabo grinders (for small areas). The crew profiled the concrete to Concrete Surface Profile (CSP) 3–4. The crew members had to wear personal protective equipment (PPE). That included half-face masks with organic vapor filters when spraying and nitrile gloves, polarized safety glasses, Ty vek suits, and boonie hats in general.
