When Should You Use Marine Grade Plywood?

Marine Grade plywood is an incredibly durable and versatile product – especially when it comes to water applications. Whether you’re building a boat or adding wood accents to your bathroom, it may be the perfect choice for the job. Our Marine Grade plywood is made with lightweight Okoume wood, waterproof adhesive and contains no voids. This guarantees long-lasting durability against water. However, it does come at a higher cost than regular plywood. Because of this, it’s important to make sure that you’re making a wise investment. So, when should you use Marine Grade plywood? We’ve made a list of some of the top projects.

Boat Building

Whether building a small wooden boat or a large yacht, using marine grade plywood can be an excellent investment. First, it’s pliable which makes it easier to work with when building curved structures like the hull of a boat. The plywood’s durability also makes it an excellent option for boat building of any scale. For boat hulls, it serves as reliable protection against leaks if the outer layer becomes scratched or damaged. If you’re building a boat, marine grade plywood is a long-lasting option that will protect your structure against damage and leaks.

Covered Docks

As you may have guessed, marine grade plywood is also a wise choice for docks. While other types of wood often have to be sanded and then treated annually, marine grade plywood will stand the test of time without this maintenance every year. For this reason, it is less likely to rot and warp because of the effects of constant water contact. The structure will remain intact and safe for many years to come.


Lake Platforms

Much like docks, lake platforms greatly benefit from using marine grade plywood as opposed to less durable plywood. If you don’t use it when building a floating structure in the water, you can count on it deteriorating prematurely. We recommend nailing and gluing several boards together and finishing the wood with a waterproof sealer. This will allow you to enjoy your floating platform for many years to come.


When it comes to interior uses for marine grade plywood, there are two places that experience the most moisture. The first is the bathroom. Using marine grade plywood can offer a different aesthetic than the standard materials used in bathrooms. It will also withstand the high moisture environment that comes from the shower and sink. Using it for flooring or a sink backsplash means you won’t be taking any chances with rot or mold in your bathroom.


As you may have guessed, the kitchen is the second place in the interior of a home that often experiences the most moisture. Over time, steam and water can compromise the integrity of lesser grade wood in your kitchen. For a waterproof backsplash in your kitchen, marine grade plywood can make a statement and ward off the effects of constant moisture from steam and more. It can also be a great option for flooring or cabinets, depending on how much water they will come in contact with.
