MDO Plywood Panels
Medium Density Overlay (MDO) Plywood (also called “signboard“) is an engineered wood panel product, originally designed for sign makers. MDO is a hardwood-plywood with a resin soaked fiber overlay between the veneer layers and on both surfaces.
- Wood-Chip stocks and special orders MDO in 1/2″ and 3/4”. Standard sheet sizes include both 2 and 4 foot widths, and lengths of 8’, 10’ and 12’.
|Panel Sizes||4' x 8'|
|Thicknesses||1/2 , 3/4"|
The top veneer layer on both sides of our MDO panels is “A” grade, providing for an extremely smooth surface, without voids, to apply the fiber overlay. The resin-soaked fiber overlays are applied with heat and pressure, forming an extremely strong, smooth, and waterproof engineered wood product.
Working With MDO
When used for cabinetmaking, MDO panels provide an excellent, very flat surface that accepts paint very well. The resin impregnated fiber layer adheres well to paint and eliminates the need for priming. Unlike many other materials, cut edges are still highly water resistant, with the added benefit of being easily painted, fully sealing the edges against water.
Routed edges are extremely stable, without splintering. But due to the high fiber and resin content, these materials are hard on saw and router blades. You should expect to resharpen your blades more often than with other engineered wood products.
Additional Info: MDO plywood sells for about half the cost of Marine plywood (such as Okoume), or about twice the cost of softwood plywood. Give us a call for current pricing.
