Is film faced plywood waterproof?

Film-faced plywood is typically made with waterproof glue, which makes it resistant to moisture and water to a certain extent. However, it is not completely waterproof and can still be affected by long-term exposure to water. To enhance its waterproof capabilities, it is often used in conjunction with a waterproof coating or sealant. Additionally, it is important to ensure that any cuts or joints in the plywood are properly sealed to prevent water from seeping in.

It's worth noting that the level of water resistance can also depend on the quality of the film-faced plywood and the type of resin used in its manufacture, as well as the conditions it is exposed to. It is always recommended to consult with a professional or the manufacturer for specific information and guidance on the waterproof capabilities of the film-faced plywood you are using.
