Originally developed for sign painting and concrete formwork industries, MDO is used as a subpurbly 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. Unlike plywood in which the liquid paint causes the grain to raise and become even more noticeable even through the paint color, MDO with it’s paper overlay hides the grain which allows a smooth surface. MDO can be either one or both smooth sides which makes it a good choice for both wall signs and post & panel signs as well.

MDO is produced in 4' x 8' sheets from 3/8" to over an inch in thickness. MDO
