High Density Polyurethane (HDU) is tough, weather resistant and lightweight (15lbs/ft2).  Its closed cell structure makes it completely waterproof which allows for the application of almost any paint finish. HDU can withstand all weather conditions and is ideal for the exterior applications including custom sign fabrication. HDU can be routed, carved, and sandblasted more efficiently than most wood substrates on the market.
