MDO Plywood in Miami – Wholesale Supplier for Contractors & Sign Fabricators

International Plywood & Lumber is Miami’s leading wholesale supplier of MDO (Medium Density Overlay) plywood, serving general contractors, sign fabricators, concrete form builders, and painters throughout South Florida since 1983. MDO’s resin-impregnated paper overlay makes it the preferred choice for any application requiring a smooth, durable, paintable surface — available for same-day delivery across Miami-Dade and Broward.

Call (305) 884-0860 for current MDO inventory, pricing, and delivery scheduling.

What Is MDO Plywood?

MDO — Medium Density Overlay — is a plywood panel bonded on one or both faces with a resin-impregnated fiber overlay. The overlay is thermally fused to the plywood face under heat and pressure, creating a surface that is:

Extremely smooth — no grain telegraph, no sanding required before painting
Highly paintable — accepts and holds paint better than any bare plywood face
Weather and moisture resistant — the resin overlay resists swelling, checking, and paint peeling in exterior applications
Dimensionally stable — the overlay controls surface movement better than raw veneer faces
Abrasion resistant — suitable for concrete forming, repeated use applications, and high-traffic surfaces

MDO vs. HDO Plywood

MDO and HDO (High Density Overlay) are both overlay plywoods but serve different purposes:

Feature	MDO	HDO
Overlay density	Medium — paintable, slight texture	High — hard, smooth, impervious
Surface finish	Best painted surface of any plywood	Hard gloss surface — not meant to be painted
Best for	Signs, painted siding, forms, cabinets	Concrete forms, industrial work surfaces
Paintability	Excellent — designed for paint	Poor — surface repels paint
Price	Moderate	Premium

For most painting, sign, and exterior construction applications in South Florida, MDO is the correct specification.

MDO Plywood Applications

Exterior Signage

MDO is the industry standard substrate for painted exterior signs. Its smooth overlay surface accepts digital print vinyl, hand-painted lettering, and direct-to-substrate inkjet printing. The resin overlay prevents moisture infiltration that causes delamination and paint failure in South Florida’s humid climate.

Concrete Forming

MDO’s smooth, durable surface releases cleanly from concrete, producing a smooth concrete face. The overlay resists moisture absorption during the concrete pour. MDO form panels are reusable across multiple pours.

Painted Exterior Siding & Trim

Architects and builders specify MDO for painted exterior applications where a smooth, knot-free painted finish is required — including exterior soffits, fascia boards, and architectural panels. In South Florida’s climate, MDO’s overlay dramatically outperforms bare plywood for paint retention.

Cabinet Backs & Painted Interior Panels

MDO is used by cabinet makers and millwork shops for painted cabinet backs, interior panels, and built-in components where a premium painted finish is required without the cost of MDF.

Marine Dock Signage & Outdoor Structures

MDO’s moisture resistance makes it suitable for marina signage, dock furniture, and outdoor structures above the waterline in South Florida’s salt-air environment.

Sizes & Thicknesses

Sheet size: 4×8 ft standard
Thicknesses: 3/8″ | 1/2″ | 5/8″ | 3/4″
Overlay: 1-side (1S) or 2-side (2S) available
Core: Typically fir or Southern Yellow Pine veneer core

Frequently Asked Questions — MDO Plywood Miami

What is the difference between MDO and regular plywood for painting?

Standard plywood has a raw wood veneer face that requires extensive prep before painting — sanding, filling grain, priming. Even then, grain telegraphs through paint and the surface can absorb moisture unevenly. MDO’s resin overlay provides a factory-smooth, non-porous surface that paints cleanly with minimal prep and holds paint far longer in South Florida’s outdoor conditions.

How many times can MDO concrete form panels be reused?

With proper release agent application and care, MDO form panels can typically be reused 10–20+ times. The overlay resists the alkaline environment of fresh concrete better than bare plywood faces. Edge sealing with paint or sealant extends form panel life significantly.

Is MDO suitable for use in South Florida’s humidity and salt air?

Yes — MDO performs significantly better than uncoated plywood in South Florida’s climate. The resin overlay resists moisture infiltration, and the exterior-rated core glue resists delamination. For applications in direct water contact, specify marine plywood instead.

Do you stock 1-side and 2-side MDO?

Yes. 1-side MDO (one face overlaid) is most common for signs and forming where only one face is finished. 2-side MDO (both faces overlaid) is available for applications where both sides are visible or exposed. Call (305) 884-0860 to confirm current stock.

What primer and paint works best on MDO?

MDO accepts oil-based and latex primers well. For exterior sign applications, sign painters typically use a light scuff sand with 220-grit, an alkyd primer coat, and a high-quality exterior latex or alkyd topcoat. The smooth surface minimizes primer coats needed compared to raw plywood.
