How is Plywood Used Outdoors?
Outdoor Plywood (Exterior plywood) is designed to withstand weather and water exposure, making it suitable for outdoor use and areas prone to moisture, such as garages. Often crafted from Douglas fir, this plywood is reinforced with waterproof glue between its layers, enhancing its durability.
Common applications for exterior plywood include decks and walkways, such as a sturdy path leading to a beach, as well as sheds, outdoor shelving, and various outdoor structures and furniture like gazebos, benches, and planters. While exterior plywood typically features visible knots and blemishes, some varieties offer a cleaner appearance, making them ideal for projects where aesthetics matter.

Exterior Grade Plywood: Characteristics and Uses
Characteristics
The best plywood for outdoor use refers to weather-resistant plywood that is suitable for outdoor use. It is durable enough to withstand frequent exposure to water and humidity. The exterior plywood is made from various types of wood such as Douglas fir, spruce, mahogany, birch, oak, and maple. Multiple layers of wood veneer are bonded together with waterproof glue to form exterior plywood. The glue hardens to create a crystalline substance, which makes the plywood more resistant to moisture and humidity. Exterior plywood is used to build decks or walkways, outdoor shelving or lining structures, and to make outdoor furniture. However, it could be more aesthetically pleasing as it may have knots or blemishes visible from the outside. Exterior plywood has different ratings for each layer, which indicates the quality of the plywood panel. These ratings include:
- A (cabinet type)
- C-D (construction grade)
- X (suitable for outdoor use)
- C-D-X (most common grade)
Uses
Exterior plywood is used for exterior, non-structural applications. Plywood is used on outdoor walls and ceilings. Some builders also use this type of plywood to make interior and exterior furniture. Exterior plywood also works great as a subfloor. Its water-resistant nature does not allow moisture to penetrate the floor whether from the surface or underneath. Some other interior applications of this type of plywood include: Sinks, Tables and Chairs, Kitchen Cabinets.

Marine Grade Plywood: Strengths and Applications
Strengths
Marine plywood is manufactured using the highest quality wood available, ensuring fewer cracks than other plywood types. Moreover, it contains more resin than conventional plywood used for exteriors, which helps prevent warping and peeling when exposed to moisture. This type of plywood is labeled as marine grade due to its ability to withstand rain, snow, and moisture for extended periods. Marine plywood can only be made of Western Larch or Douglas Fir, must have five or more layers, and have fewer air pockets and smaller gaps than regular plywood.
Applications
Marine plywood is a great choice for outdoor furniture or flooring construction due to its resistance to harsh weather conditions and long-lasting durability.
Pressure-Treated Plywood: Benefits and Considerations
Benefits
The advantages of pressure-treated plywood are varied and immense. From increased durability to greater structural integrity, these benefits all contribute to the longevity of structures using this material.One of its key advantages is its ability to resist rotting and decomposing, which helps safeguard buildings from environmental damage.
Moreover, pressure-treated plywood has excellent dimensional stability properties, reducing the risk of warping, twisting or breaking over time. Its insect resistance is particularly noteworthy, providing significant protection from termites, carpenter ants, and other pests. These natural antibacterial properties also minimize the need for regular maintenance and repairs, resulting in long-term cost and time savings.
Considerations
Pressure-treated plywood is known for its durability, moisture resistance and antibacterial properties, making it a versatile choice for both indoor and outdoor projects. Here are some notable applications of this material:
- Outdoor floors and decks: Pressure-treated plywood is suitable for outdoor deck and patio installations, with the ability to withstand all weather conditions, ensuring long-term sustainability for these areas.
- Privacy Screens: Pressure-treated plywood panels are commonly used to construct fences and privacy screens, providing the protection and privacy needed for outdoor spaces that are not degraded.
- Structural frames and sheathing: Pressure-treated plywood is a reliable material for the construction of structural frames and sheathing, ensuring durability and moisture resistance in humid construction environments.
- Planting pots: Gardeners often use pressure-treated plywood to construct planting areas, ensuring stability and moisture resistance for plants.
- Playground equipment and playhouses: Pressure-treated plywood is a safe and reliable material for playground equipment and playhouses, ensuring a safe and long-lasting play environment for children.
Applications of Outdoor Plywood
Outdoor plywood is a reliable and flexible solution for a wide range of outdoor projects. It is treated for weather resistance and durability, making it suitable for decking, fencing, cladding, and other structural components in outdoor environments.
