Medium density overlay panel

Medium density overlay panel, or MDO panel, is a paintable surface made of plywood with a weather-resistant resin overlay bonded to the wood by heat and pressure. The overlay, which has at least 27% resin content,^[1] resists water, weather, wear and degradation. A similar product with a more rugged, smoother surface is called high density overlay (HDO) plywood.^[2]^(p4)

Development

Originally developed for sign painting and concrete formwork industries, MDO is also used for other applications^[2]^(p5) as a paintable surface. Paint finishes on MDO are up to three times more durable than the same finish applied to ordinary plywood

It is a plywood product, with a paper face overlaid on the plywood substrate with an exterior grade (usually) phenolic adhesive. MDO is designed to have a smooth, paint-receptive surface. One or both faces can be surfaced with paper, and is produced in 4' x 8' sheets from 3/8" to over an 3 inches in thickness.
