WHAT IS MEDIUM DENSITY OVERLAY PLYWOOD

Medium Density Overlay (M.D.O.) plywood is an exterior-grade plywood panel with a resin-impregnated fiber overlay bonded to one or both faces under heat and pressure. The overlay creates a smooth, uniform surface that resists moisture, abrasion, and weathering while retaining the strength and dimensional stability of plywood. MDO is commonly specified where a paintable, durable substrate is required, such as signage, exterior cladding, and industrial applications.

SPECIALTY APPLICATION

MDO plywood is considered a specialty panel because its resin-treated overlay provides a smoother, more durable surface than standard plywood, making it ideal for painted finishes, exterior siding, truck and trailer linings, and other applications demanding moisture resistance and long-lasting surface performance.

FEATURES

Resin-Impregnated Overlay – Resin-saturated fiber surface bonded under heat and pressure produces a smooth, paint-ready face.

Weather & Moisture Resistance – Exterior-grade construction with a protective face layer improves durability in wet and outdoor conditions.

Superior Paint Adhesion – Overlay surface accepts primer and paint more consistently than untreated plywood.

Dimensional Stability – Maintains strength, rigidity, and balance typical of plywood panels.

Workable Material – Can be cut, routed, and fastened with standard woodworking tools.

RECOGNIZED CERTIFICATIONS
