Wood with strengthening coating

An increased durability wood product comprising

• a wooden board or plank having a longitudinal length and at least three sides, the sides defining a polygonal cross section along the length of the wooden board or plank, and
• a polyurethane-urea hybrid external coating directly adhered to at least two opposing sides, and said polyurethane-urea hybrid coating comprising 100% elastomeric formulation applied by spraying and cured in place and having a thickness between 25 and 35 mils, and wherein said polyurethane-urea hybrid coating provides a coated board having a structural load bearing integrity increased by at least a a strength factor of 10 compared to an untreated board of identical dimensions when subjected to impact testing, and wherein said polyurethane-urea coated wooden board or plank is configured to be cut, shaped, or drilled using standard wood sawing equipment, wherein said polyurethane-urea hybrid coating is self-healing about fastener penetrations, and wherein said polyurethane-urea hybrid coating resists moisture-induced deformations and cupping, and wherein said polyurethane-urea hybrid coating resists moisture absorption such that the coated board increases in weight by less than 1% after complete submersion in water for 48 hours.
