Tips on How to Protect Plywood Doors from Moisture and Termites: Longevity Made Simple
May 9, 2025
When constructing or renovating a home, something to consider to make your materials last longer and stronger is maintaining your plywood doors. Plywood doors are great because they are aesthetically pleasing and functional. However, like everything else, plywood doors have two major issues: termites and water. If not sealed off, these two issues may lead to destruction, rotting, or the door becoming unusable.
It's a good idea to know how to guard your plywood doors against these problems. In this guide, we're going to show you some easy tips to prevent your plywood doors from termites and moisture, so they remain strong and attractive for years.
Why plywood door protection is a good idea
Plywood doors are strong and durable, but plywood is typically only a thin coating of wood, which makes it particularly susceptible to termites. Termites can weaken and damage wood by eating it, weakening the door and rendering it unsightly. Plywood also readily swells, curves, or weakens in wet conditions, and this causes the door to be less robust and functional as time goes by. By securing your plywood doors against these, you can keep them in decent condition and fully functioning.
How to Protect Plywood Doors from Termites
Termites are among the worst insects that can infest wood doors. These small insects feed on the cellulose in wood, which soon causes damage. Fortunately, there are numerous methods to safeguard your plywood doors against termites:
-
Use Termite-Proof Plywood
One of the most effective methods to prevent termites is to use termite-proof plywood. Companies like Royale Touche provide termite-resistant plywood that is chemically treated to repel pests.
-
Use Anti-Termite Treatment
If you are making use of regular plywood, you might apply anti-termite treatment on the door surface. Such treatments are either in spray or liquid form that you can spray or drizzle on the edges and surface. Don't forget to regularly reapply the treatment for continued protection.
-
Install Physical Barriers
For outside doors, installing a physical barrier such as a metal mesh at the bottom of the door can prevent termites from reaching the wood.
Preventing Moisture Damage to Plywood Doors
Moisture can also damage plywood doors. Plywood swells, bends, or even rots when it comes into contact with water. Here are a few methods to prevent moisture from destroying your plywood doors:
-
Apply a Water-Resistant Finish
The best method to prevent moisture damage is to use a water-resistant finish. This provides a protective layer that prevents water from penetrating the wood. Select a high-quality sealer for wooden doors, and reseal the door from time to time.
-
Install BWP Plywood
BWP plywood is used to withstand water damage and thus is a suitable option for regions with heavy rain or high humidity.
-
Correct Installation
Ensure your plywood door is correctly installed with no gaps left in the frame. Sealing the door edges correctly will prevent moisture from entering. Also, make sure the door is hung in a manner that ensures air circulation to minimize the buildup of moisture.
-
Ventilation
Good airflow around your plywood doors will prevent moisture accumulation. In the case of exterior doors, ensure that the door area is well-ventilated so that moisture escapes.
