What is MDO?
George VondriskaDescription
Plywood, MDO, and MDF are alike in that they all come in 4’x8’ sheets and are typically available in 1/2” and 3/4” thicknesses. However, there are key differences that buyers should consider when deciding which material is best for their project:
Plywood core vs. composite: One of the main distinctions between MDO and MDF is that MDO has a veneer plywood core, making it much lighter and easier to handle than MDF.
Moisture resistance: MDO uses waterproof adhesives to bond its layers, making it resistant to delamination when exposed to moisture. This makes MDO a great choice for outdoor painted projects.
Paintable surface: MDO has a smoother surface than plywood, providing an excellent substrate for painted surfaces, as the grain won’t show through.
So, when considering what MDO is, remember these three key benefits: 1) lightweight, stable sheet material, 2) resistance to moisture-related delamination, and 3) a superior surface for painting.
