An explanation on how to use waterproof plywood in homes


Waterproof plywood is gaining popularity as a practical substitute for conventional plywood among modern homeowners. Long-term structural damage due to water is a significant concern, especially for wooden interiors, which are susceptible to water-related issues and require special attention to prevent damage. Opting for waterproof plywood is a wise decision to mitigate the risks associated with moisture accumulation. Integrating this material into your interiors can result in substantial long-term savings. Continue reading to explore further details about waterproof plywood and the reasons to contemplate its usage.

Applications of waterproof plywood

Waterproof plywood has accumulated a wide range of applications due to its functionality. Here are some of them:

Marine construction

Waterproof plywood is a crucial material in the marine industry due to its superior ability to withstand constant exposure to water and moisture. Therefore, it is widely used for the construction of boats, ships and marine vessels.

Outdoor furniture

Garden furniture, decks and outdoor structures are more exposed to harsh weather conditions like rain and humidity as compared to indoor wooden structures. This makes waterproof plywood the ideal solution to increase the longevity of outdoor furniture.

Exterior construction

Exterior applications of wood such as in roofing or cladding require a more resilient alternative to traditional plywood. Waterproof plywood is highly suited to exterior projects involving the exposure of wood to moisture elements.

Bathrooms and kitchens

Bathrooms and kitchens are interior areas that experience high humidity levels and water exposure. Cabinets, shelves and fittings in these areas can be made using waterproof plywood to prevent damage and ensure longevity.

Concrete formwork

Waterproof plywood is an essential component in creating the formwork of concrete structures during the construction process. The water-resistant properties of the plywood prevents it from getting swollen or deformed when exposed to the wet concrete.

Signage and billboards

Outdoor signages and billboards used for advertising require materials with superior weather-resistant properties. This makes waterproof plywood a perfect choice for this application since it provides both durability and resistance to moisture.


Large vehicles like trailers and trucks that have elaborate flooring and interior components can benefit from the application of waterproof plywood. This would come in use when the vehicle is exposed to heavy rain or extreme weather conditions during transportation.

Temporary shelters

Waterproof plywood is often used to build sturdy temporary structures in areas where there is a requirement for habilitation. These weather resistant structures are found in disaster camps and camps for the homeless.

Waterproof plywood: Pros and cons

Let’s now have a look at the list of advantages and disadvantages waterproof plywood brings forth to help you decide upon its utility in your arsenal.

Pros Cons
It undergoes specialised treatment to enhance water resistance properties and resists deterioration and warping, making it ideal for applications in situations with prolonged water exposure. Due to additional treatments, it is more expensive than regular plywood and might hamper budget considerations of the construction project.
It is engineered to show greater durability than regular plywood and enhances the longevity of the structure in harsh environments of physical stress. The additional protective layers might add to the weight of the material, making it unsuitable for some applications such as transportation, where weight considerations are crucial.
Waterproof treatments also ensure protection against fungi and bacteria caused by constant moisture exposure. It is not available in a vast range of finishes and is not as aesthetically pleasing as regular finished plywood.
It is highly versatile and adaptable and suited to various applications ranging from marine to construction. The treatment process uses chemicals that might be harmful to the environment and generate untreatable waste.
It retains its stability in the harshest conditions without getting deformed, making it an efficient choice for areas with high rainfall. It is not as widely available as regular plywood due to limited access to specialised materials required to manufacture it.
