MDO Signboard

MDO (Medium Density Overlay) board is an exterior type plywood with a weather resistant resin overlay bonded to the wood by heat and pressure. This process fuses the molecules of the overlay with the fibers of the wood to form a bond as strong as the wood itself.
MDO has all the advantages of regular plywood as well as additional properties. The overlay, which has 28% resin content, resists water, weather, wear and degradation. It has a smooth surface not possible with regular plywood, with a texture that paint can grip with remarkable tenacity. Paint finishes on MDO board signs are up to three times more durable than the same finish applied to ordinary plywood.
Although MDO is available with the overlay on one side only at a lower price, MDO with the overlay on both sides is more resistant against warping, and is better sealed against the elements. Because of this, we use only the 2-sided overlay product, whether we are lettering on one side or both sides.
We buy this MDO unpainted. To achieve a smooth lettering surface, we prime and paint both sides with foam rollers. We use only top quality oil based enamel for the finish coats.
This material is used for board signs of a more permanent nature than temporary signs made with vinyl faced signboard. Life expectancy of 6-8 years; we have seen them look good for as long as 10 years.
