This GIB specifically addresses glass that has been painted on the back side, or second surface, that is not exposed to direct human contact. There are many factors to keep in mind when determining the durability of backpainted decorative glass. It is generally installed in an interior setting and protected from the elements; however, it is still subject to an environment and application that requires the product to be durable. Backpainted glass may be exposed to mechanical or chemical attachments or cleaners, moist environments due to proximity of water or plumbing fixtures, exposure to ultra violet (UV) light, heat through windows, and various methods used for installation. This document will provide some of the factors to consider when determining the durability of a backpainted product and provide direction for testing to determine a products' durability.
