Film faced plywood for concrete formwork — a complete guide

Introduction

In concrete construction, the choice of formwork material directly impacts surface finish, project timeline, and total cost. Film faced plywood is the industry standard for slab, beam, column, and wall formwork across Asia, the Middle East, Africa, and Latin America. This guide explains the specifications you need to know before importing.

What Is Film Faced Plywood?

Film faced plywood is a phenolic-coated plywood made by bonding a layer of impregnated phenolic film onto the surface of birch, poplar, hardwood, or eucalyptus plywood under high temperature and pressure.

The phenolic film creates:

• A smooth, glossy concrete finish (no need for additional plastering)
• Waterproof surface for repeated reuse
• Chemical resistance against concrete alkali

Grades Explained

When sourcing film faced plywood, you'll encounter grades like A/A, A/B, B/C, C/C, etc. The first letter refers to the front face, the second to the back.

• A/A: Smooth both sides, no repairs — premium projects, fair-faced concrete
• A/B: Smooth front, minor repairs on back — most common for walls and columns
• B/C: Visible repairs — sub-base formwork, hidden concrete
• C/C: Lowest grade — temporary works

How Many Times Can It Be Reused?

The reuse cycle depends on:

1. Glue type — WBP (phenolic) gives 15–30+ reuses; MR (melamine) gives 5–10
2. Thickness — 18mm lasts longer than 12mm
3. Core wood — Birch > eucalyptus > poplar in durability
4. Site handling — Proper release agent and edge sealing extend life
5. Concrete pressure — Columns and walls wear faster than slabs

For most construction projects, 18mm WBP film faced plywood with birch or combi core delivers the best balance of cost and performance.
