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
- 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

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.
