Film-Faced Plywood vs MDO: Choosing the Right Formwork Panel

Concrete formwork is one of the largest single applications for structural plywood worldwide. Two panel types dominate the formwork market: film-faced plywood and MDO (Medium Density Overlay). Both are used on construction sites but for different purposes and with different performance profiles.

Film-Faced Plywood

Film-faced plywood has one or both faces laminated with phenolic paper (typically 220–240 gsm) under high pressure. The result is a hard, smooth, waterproof surface that releases cleanly from concrete.

Key characteristics:

• Brown or black phenolic film face
• Very smooth concrete finish (Class A surface)
• High reuse cycles: 10–20+ pours with proper care
• WBP phenolic core glue bond throughout
• Thickness: 15mm, 18mm, 21mm most common
• Sizes: 1220×2440mm standard; 1250×2500mm available

Applications: wall forms, slab decking, column forms, beam forms anywhere a smooth concrete face is needed.

MDO — Medium Density Overlay

MDO board has one face bonded with a resin-fibre overlay that creates a very smooth, paintable, stable surface. It is not the same as film-faced plywood.

Key characteristics:

• Smooth surface designed for paint adhesion, not concrete release
• Lower reuse cycles in concrete applications (3–8 pours)
• Better suited for repeated painting than for high-cycle concrete use
• Typically used in USA market for signage, soffits, painted exterior cladding

Applications: signs, painted soffits, exterior siding, one-off concrete pour where smooth face is needed but reuse is not.

Anti-slip film-faced plywood

For floor decking and access platforms, EBP also supplies anti-slip film-faced plywood with a wire-mesh or grid pattern pressed into the face. This meets EN 13553 and is standard for scaffold planks, vehicle ramps, and truck flooring.
