If you’ve ever embarked on a do-it-yourself project or worked within the realm of construction, you are likely quite familiar with plywood. This versatile material, lauded for its strength and practicality, is instrumental in many outdoor applications. However, the broad spectrum of available types can make the task of choosing the best plywood for outdoor use somewhat daunting. Fear not, as this comprehensive guide is designed to steer you through the labyrinth of exterior plywood, equipping you with the knowledge necessary to make an informed decision.

The Versatility and Advantages of Plywood in Outdoor Applications

Plywood, with its notable durability and cost-effectiveness, has quickly become a popular choice for a myriad of outdoor projects. This material’s applications are as varied as they are numerous. Plywood can be frequently spotted in the construction of outdoor fencing, where its inherent robustness becomes a significant advantage, providing a secure and sturdy barrier against various elements.

Decking is another area where plywood comes into its own. With the correct treatment and consistent maintenance, plywood decks can withstand the test of time, serving you faithfully for many years.

Plywood also finds its place in the construction of sheds and exterior claddings. Plywood sheds are economical and relatively straightforward to construct, making them a firm favorite among many homeowners. In terms of cladding, plywood strikes an excellent balance between aesthetics and functionality. Its strength and resistance to weather elements make it an ideal material for outside walls and a host of other exterior applications.

Deep Dive into the Different Types of Exterior Plywood for Outdoor Use

The world of exterior plywood is vast, diverse, and, at times, complex. The most common types suitable for outdoor use include Softwood Plywood, Hardwood Plywood, and Marine Plywood. Each type comes with its unique set of strengths and weaknesses, making them more or less suitable for certain applications.

Softwood Plywood is typically derived from coniferous trees like pine, spruce, and fir. Its strength and affordability have made it a popular choice for numerous construction projects. Hardwood Plywood, derived from deciduous trees like birch, oak, and maple, is revered for its smooth finish and resistance to moisture. This type of plywood is ideal for projects requiring a visually appealing exterior.

Marine Plywood, as the name suggests, is predominantly used in marine environments. It’s the first choice for projects exposed to high moisture levels, given its superior water resistance properties.

Elucidating the Key Differences Between Exterior Plywoods

While all exterior plywood types are designed with outdoor use in mind, their levels of resistance to moisture can vary considerably. For instance, marine plywood is waterproof, making it a superb choice for areas constantly exposed to water. This type of plywood undergoes a unique manufacturing process where it’s treated with special adhesives to boost its water resistance.

Exterior grade plywood, while not entirely waterproof, can resist a significant amount of moisture. This makes it a practical option for environments that are less damp. It’s treated with chemicals that repel water and prevent decay, thereby enhancing its longevity.

Exploring the Lifespan and Maintenance of Exterior Graded Plywood

The durability of exterior grade plywood hinges primarily on its exposure to moisture and the level of maintenance it receives. When properly treated and maintained, exterior graded plywood can last for an impressively long time. Regular inspections, timely repairs, and the application of sealants and paints can significantly prolong the lifespan of plywood. Given its longevity and affordability, it represents a wise investment for outdoor projects.

Considering Alternatives To Outdoor Plywood

While plywood for outdoor use is a popular choice, it’s always beneficial to understand other alternatives. Some options include exterior grade OSB (Oriented Strand Board), pressure-treated lumber, and exterior grade MDF (Medium Density Fiberboard).

OSB is a composite wood product, similar to plywood, and is often used as a plywood alternative due to its strength and lower cost. Pressure-treated lumber is wood that’s been infused with chemicals to increase its resistance to decay and insects, making it eminently suitable for outdoor use. MDF, on the other hand, is an engineered wood product made from hardwood or softwood residuals broken down into wood fibers.


In the realm of outdoor use, the best plywood is one that aligns with your specific needs and budget. Whether it’s exterior plywood, marine plywood, or another alternative, understanding the characteristics and benefits of each can significantly aid your decision-making process. It’s important to bear in mind that no plywood is entirely waterproof. However, with the right treatments and regular maintenance, your outdoor plywood can withstand the elements and serve you faithfully for many years.
