In Thailand’s fast-growing construction industry, choosing the right formwork material is crucial for quality, speed, and cost-efficiency. Among many options, film faced plywood has become the top choice for contractors thanks to its durability, smooth surface, and resistance to water damage. This guide will help Thai builders understand why it is widely used in concrete formwork projects.

What is Film Faced Plywood?

Film faced plywood is a type of engineered wood panel. It is made from multiple layers of wood veneer bonded together with strong adhesive, and its surface is coated with a high-density phenolic film. This coating makes the panel resistant to moisture, wear, and chemicals. The result is a sturdy board with a smooth finish that prevents concrete from sticking, ensuring cleaner surfaces after formwork is removed.

Compared to ordinary plywood, film faced plywood is specifically designed for repeated use in demanding construction environments. Contractors in Thailand prefer it over traditional wooden boards because of its longer lifespan and superior concrete finish.

Why It’s Used in Concrete Formwork

Concrete formwork requires materials that can withstand heavy loads and maintain their shape under pressure. Film faced plywood offers several advantages:

• High strength: Cross-laminated veneer structure provides excellent load-bearing capacity.
• Easy release: Phenolic coating reduces the need for release agents, saving labor costs.
• Smooth finish: Produces clean concrete surfaces with minimal defects.
• Reusable: Depending on project conditions, panels can be reused 10–20 times or more.

For contractors in Bangkok, Chiang Mai, and Phuket, film faced plywood is now standard in building foundations, bridges, and housing projects.

Advantages in Thailand’s Rainy Season

Thailand’s tropical climate, especially during the monsoon season, brings challenges for construction. Regular plywood absorbs moisture, leading to swelling, warping, and reduced strength. Film faced plywood, on the other hand, is designed to resist water:

• Moisture resistance: Phenolic surface prevents water penetration.
• Dimensional stability: Less expansion and contraction compared to normal wood boards.
• Durability: Panels remain strong even after repeated wet-dry cycles.

This makes it ideal for Thai contractors who often work in humid environments. By using film faced plywood, construction delays due to rain can be minimized, reducing overall project costs.

Standard Sizes & Reuse Cycles

Film faced plywood is available in standard international dimensions, making it compatible with global construction practices. The most common size is 1220mm × 2440mm (4ft × 8ft), with thickness ranging from 12mm to 18mm.

When properly handled, stored in dry areas, and cleaned after each use, film faced plywood can extend its lifespan, providing contractors with excellent cost savings per project.

Conclusion

For contractors across Thailand, film faced plywood is more than just a building material—it is a proven solution that ensures durability, quality, and efficiency in concrete formwork. With resistance to rain and repeated use cycles, it has become the contractor’s reliable partner in both small and large-scale construction projects.
