Project Technical Rating
Raider commercial building painters were contacted by an HVAC Fan manufacturer Toro-Aire with a big problem. They were just days away from the opening of a new (NOAA http://www.noaa.gov/ ) high-tech weather research facility in La Jolla CA that had been put on hold because a necessary exhaust fans coating had failed and the rust forming on the machine was becoming airborne and threatening other high-end machinery. With liquidated damages looming and their reputation on the line, they needed help.
This project presented challenges that caused other coating contractors to pass on it. We knew it was not only within our capability, but that we could do it efficiently and deliver a quality product.
Safety was essential. We used extensive fall protection measures, held daily safety checks and meetings, and employed an on-site safety director.
To remove existing rust and form a profile on the steel surfaces that would allow the new coating to adhere properly, we used a grinding method to prep large surfaces, and needle-nosed guns for small corners and tight areas. Immediately following prep, we applied a rust-inhibiting epoxy coating to the surfaces to prevent flash rust from the extremely humid environment.
In order to minimize the structure’s exposure to humidity, we divided the process between two teams—one to prep the surfaces, and the next directly behind them to apply the first coating of epoxy.
Following the initial phase, we applied additional coats of epoxy to provide superior protection.
The project was completed ahead of schedule, including the added scope. The client, contractor, and end user were all appreciative that we were able to hold them to their schedule. The specialty DTM product used created a great finish and with a a total of 3 coats the longevity of the finish will allow for years of operation.
