What is Medium Density Overlay?
Originally developed for traffic signs and concrete formwork industries, Medium Density Overlay (MDO) is engineered plywood with a resin treated fiber applied to both faces. This gives MDO an extremely durable and smooth finish that is easy to paint. Additionally, MDO is specifically rated for exterior use, which means it is safe from the harsh elements, insects, or other outdoor hazards. It's a perfect choice when needing additional protection for exterior doors in tough environments.
