Let’s face it: there are dozens of types of plywood, and each one can be used for different purposes (i.e., indoor or outdoor use). Plywood has been one of the top-produced materials in North America for many years. According to the APA: The Engineered Wood Association, there were nearly 4 billion square feet of plywood produced in the United States by 1954. One of the most efficient kinds of plywood is Marine-Grade Plywood. Made of Douglas fir (or sometimes Western Larch), it is extremely lightweight, durable, and strong. It is the only type of plywood that can withstand being constantly submerged in water. Thus, it is perfect for outdoor projects like boat hulls, docks, and piers.

Characteristics Of Marine-Grade Plywood

Marine-Grade Plywood has plies of A-B grade. Each of these two letters represents one side of each ply, which is stacked perpendicularly to the next one. This type of plywood includes waterproof glue designed to keep the plies together, so it can resist virtually any level of moisture. Marine-Grade Plywood does not need to be treated with chemicals in order to avoid decay. Rather, it is made from exterior-grade plywood, which contains fewer voids and gaps than interior-grade plywood, making it less susceptible to decay. You may be wondering how Marine-Grade Plywood should be treated, including whether or not it should be sealed. The answer to this question is yes, Marine-Grade Plywood should be treated. Here is a step-by-step guide on how to do this.

How To Seal The Plywood

Although Marine-Grade Plywood is strong, durable, and heavily-resistant to moisture, an additional coat of seal is typically needed to prevent moisture from the wood’s doors. Some of the essential things you’ll need for this process include:

Acetone

Paper towels

Sanding block

Sandpaper

Foam roller

Paint basin

Tipping foam brush

Epoxy moisture sealer

Wipe/Clean Surface Of Plywood

Use paper towels or a cloth dipped in acetone in order to clean the surface of the plywood. The purpose of this is to get rid of grease and other contaminants. It’s important to let the acetone dry. This step should take approximately one to two hours.

Fine-grit sandpaper is considered ideal for sanding wood. It should be used for several minutes for the best results and a cloth should be used to eliminate sawdust particles.

Apply Sealant With Foam Roller

After pouring a small quantity of moisture sealer into a paint basin, dip the foam roller into the sealer. In order to eliminate the majority of the sealer, roll the brush against the paint basin’s side. It is recommended to roll the paint you choose to use onto a 2-by-2-foot area in order to verify that the sealer doesn’t dry too quickly. Be sure to focus on one section at a time until a thin coat covers the whole plywood. In order to eliminate brush marks from the sealer, drag a foam tipping brush over the sealer while it is wet. Remember to paint horizontally, not vertically.

Allow To Dry

It should take between one and two hours for the sealer coat to dry. You can add a few extra thin coats during this last step, although at this point you can alternate between vertical and horizontal strokes. Five thin coats of the sealer should be more than enough to finish your sealing project.
