The primary challenge that wood products face in exterior, appearance-oriented markets is the perception that they require frequent maintenance. Lengthening the intervals between re-finishing would help wood compete in exterior, appearance-oriented markets. On-going field tests evaluating the ability of protective pre-coats to enhance the performance of transparent and semi-transparent finishes are showing promising results. However, additional protection from UV and visible light would be helpful, particularly for the transparent finish. The present work reports the initiation of a new field test to evaluate the ability of a pigmented protective pre-coat to enhance the performance of transparent and semi-transparent finishes.
