Abstract: To design effectively for durability, one must actively and honestly assess the material properties and limitations of each of the components in the design system; wood or wood composite, and the coating. Inasmuch as wood coatings are manufactured to specified tolerances from known materials, we have control of that component of the system. Compared to manmade substrates such as steel, with wood we have virtually no control over the material properties of the substrate in coated wood systems. Despite this lack of control, with sufficient understanding of wood and the wood -coating interface, we can design coatings to meet specific criteria. Our understanding of wood and the specific nature of wood -coating interfaces is thus what limits our ability to design coatings in a highly targeted fashion. To begin to identify the aspects of wood structure relevant to coating durability, wood must be understood as a material of biological origin.
