Some tips for choosing the right outdoor plywood for your project
Plywood is a popular choice for numerous projects due to its strength, versatility, and affordability. For outdoor projects like decks, shelving, or even boats, various types of outdoor plywood are available. Both the construction grade and the appearance of the plywood matter, depending on the specific requirements of your project.

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.

Types and Grades of Outdoor Plywood

It is important to understand the characteristics of different types of outdoor plywood before starting a project, as each type behaves differently due to its natural composition and susceptibility to outdoor conditions.

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.
