One hundred thousand square feet of traffic deck inside a Government of Canada parking garage needed to be restored (two levels of a three-story garage), and the contractors had their work cut out for them. The building was fully occupied by government employees and could not be vacated while the application took place. It was winter and relocating vehicles to the street was not a viable option. Minimal disruption to occupants was absolutely critical so materials used to coat the deck had to contain low odor and be low VOC, and the job had to be done quickly. In addition, the new deck coating system would have to bond to an old urethane deck coating after a cleaning solution was used to strip off extensive oil stains.
Alti Construction selected the Vulkem® 360NF/950NF Deck Coating System because it’s designed for fast-track application schedules and is specifically designed for heavily occupied areas where odor and VOCs are concerns. Vulkem 360NF Polyurethane Basecoat and Vulkem 950NF Polyurethane Topcoat are quick-curing, minimal-odor and low-VOC.
Alti Construction performed various tests to assure that the new coating and primer would adhere to the existing coating and cleaning agents. In order to allow for areas of the garage to be utilized by government employees while work was underway, one level was open for traffic while the other level was being worked on. Approximately 250 cars per level were displaced. Because of the incredibly fast cure properties of the Vulkem system, though, cars could return to the garage in 24 hours instead of two to three days.
