TMI Coatings was contracted by the Air National Guard to abrasive blast and paint the exterior steel structure of aircraft hangars at their facility. The existing paint was lead based paint requiring strict worker protections and environmental controls. Additionally, the continuous occupation and use of the surrounding hangar and office areas were maintained throughout the work. Scaffolding was erected and the structure was fully contained to collect all dust and debris during sandblasting. Negative air pressure within the containment was maintained by use of dust collectors. The entire structure was primed with a zinc rich organic primer, high solids epoxy intermediate coat, and finish coat of urethane.
