Plywood is categorized into different grades and types because it is a highly versatile engineered wood with countless applications. Among the various grades, a waterproof plywood is the superior grade in terms of water resistance. Exposure to water has no effect on the core of the best waterproof plywood. It contains a synthetic adhesive, and hardwood veneer is used in its layers. Let’s explore the uses and science behind this plywood type.
What is Waterproof Plywood
A waterproof plywood is an engineered wood built to survive in highly humid areas or continuous water contact. This plywood was developed to overcome the challenges of swelling, peeling and mould development due to the presence of high moisture in the areas where ventilation is not enough. For commercial purposes, BWP or marine-grade plywood is considered waterproof plywood.
How It Resists Damage By Water Contact
Before the development of phenol formaldehyde for binding the veneers, plywood used to be bonded by water-soluble glues. This restricted the use of plywood in areas where water or moisture exposure is high. With the synthetic glue that is phenol formaldehyde, the bond between the veneer became strong, and the adhesives remain intact without reacting with water molecules. It creates a plywood so dense that it becomes harder for the water molecules to seep into the surface. Hardwood veneer, high-temperature and pressure treatment, and cross-laminated construction are the manufacturing methods that make the best waterproof plywood.
Top Uses of Waterproof Plywood
Marine
Ships, boats, and dockyard structures are the most popular applications where waterproof plywood is used. These structures are either directly exposed to water and corrosive chemicals or high levels of moisture.
Coastal Homes
Being located in coastal areas, the furniture in these homes needs to resist moisture and water-related damage. The salty and humid air can cause ordinary plywood to warp and swell sooner than expected. But the waterproof plywood lasts much longer.
Bathroom Cabinet
Bathroom vanities, storage cabinets, and partitions require materials capable of handling continuous moisture exposure. Waterproof plywood provides durability and stability in these environments.
Modular Kitchens
Drawers, shutters, and undersink cabinets are often built with waterproof plywood because these fixtures often face the challenges of steam and spills. The unique grain pattern also elevates the aesthetic value of the kitchen.
Outdoor Furniture
Balcony and garden furniture and structures such as a swinging chair, pergolas, patios, use the strength and water resistance of the waterproof plywood.
Exterior Cladding
Wall cladding and exterior facades in homes look natural and survive in humid, hot and extreme cold conditions as they are made up of waterproof plywood.
Shuttering Plywood
Though these are used for temporary formwork, their waterproof quality makes them suitable to enable curing of wet curing while strongly maintaining the shape of the column or beam.
