Description
English: The 10-year test results of the National Park Service's Wood Stain Durability Test are shown. The upper half of the test board was exposed in a window to north light. The bottom was covered during the test period. Comparison of the corresponding exposed and unexposed areas reveals the extreme susceptibility of certain commonly used wood stains to damage by light.
