with a weather-resistant
resin overlay bonded to the wood by heat and pressure. The overlay, which has at least 27% resin content,
resists water, weather, wear and degradation. A similar product with a more rugged, smoother surface is called high density overlay (HDO) plywood.
Development
Originally developed for sign painting and
concrete formwork industries, MDO is also used for other applications

with an exterior grade (usually)
