“Film Faced Plywood vs Marine Plywood: Which Do You Need?”은(는) 아직 한국어에서 사용할 수 없습니다

Film faced plywood is highly water-resistant but not permanently waterproof. The phenolic film seals face surfaces against moisture during concrete pours, and WBP adhesive prevents delamination. However, unsealed cut edges absorb moisture over time. For temporary and cyclical wet exposure (formwork), it performs excellently. For permanent submersion or decades of outdoor exposure, marine plywood is the better choice.

It can survive a pour, but it is not recommended. The bare wood surface bonds to concrete, making stripping difficult and damaging both the panel and the concrete finish. Film faced plywood is purpose-built for formwork and delivers a cleaner finish, easier stripping, and more reuse cycles at a lower cost per sheet.

Film faced plywood is cheaper per sheet at equivalent thickness. Marine plywood's void-free core requirement increases material cost. For formwork applications, the cost advantage is amplified by film faced plywood's superior reuse cycle count — the cost-per-pour is significantly lower.

For outdoor structural applications, EN 636-3 rated film faced plywood (such as Vinawood Pro Form with WBP phenolic adhesive) provides excellent moisture resistance with a Class 3 exterior bond. For non-structural outdoor use, exterior-grade hardwood plywood with WBP adhesive and a painted or sealed finish is a practical, cost-effective option.
