Painted aluminum extrusions are a common architectural material used in the manufacture of windows and door frames. The applied coatings, typically in a shop atmosphere, may not always work once installed in the field due to a variety of fabrication defects and or exposures. The correct coatings may be selected, though without careful attention to the fabrication process, the coating may fail miserably, even before installation is completed. In addition, the expected exposure of the aluminum is not always provided to the architect/designer which can result in selecting an improper coating material. Both actions result in premature coating failures. This paper illustrates examples of these concerns and the resulting options to correct these coating defects in the field.
