Film-faced plywood is a multi-layer timber plywood with a protective film surface. It is widely used as a concrete-formwork facing material because the coated surface provides a smoother contact face and supports repeated use when the sheet is handled correctly.
Why Is Film-Faced Plywood Used for Concrete Formwork?
The coated face helps create a smoother concrete-contact surface and can make stripping easier. Reuse depends on plywood quality, support layout, edge protection, stripping method, cleaning and storage.
18 mm and 21 mm Plywood
18 mm and 21 mm are common thickness options. Thickness should be considered together with support spacing, panel dimensions, concrete pressure and the overall formwork arrangement.
Is Film-Faced Plywood Waterproof?
Film-faced plywood should not be treated as completely waterproof. The film surface and suitable adhesive system improve moisture resistance, while cut edges, holes and damaged film remain more vulnerable to water.
Film-Faced Plywood vs Plastic Plywood
Film-faced plywood has a layered timber core, while plastic plywood has a polymer-based body. Their behavior under moisture, mechanical damage and repeated use is therefore different.

Plywood vs OSB
Plywood is made from layered veneers, while OSB is made from oriented wood strands. Their structure and surface performance are different, especially for concrete-formwork applications.
