Our page top photo of a painted sign (The Big Tomato luncheonette in Poughkeepsie, NY) shows variation in two paints differing by color and chemistry, applied at the same time to the same surface. Also see PAINT FALURE, DIAGNOSIS, CURE, PREVENTION for details of paint failure cause, diagnosis, cure and prevention.

The USDA Forest Service Forest Products Laboratory (FPL) has done extensive research on how to keep paints and stains on wood sidings and trim. In general, they recommend paint for the longest lasting finish and best protection of the underlying wood, followed by solid or semi-transparent stains. Clear finishes need the most frequent recoating and offer the least protection from water damage and UV radiation.

How long a finish will last depends on many variables, including the quality of the finish, type and texture of wood, application conditions, and exposure. South- and west-facing walls get the most sun and are, therefore, often the first to need recoating.
