Can you use regular plywood for boat decking?

As an alternative to marine ply, you can use exterior grade plywood. Although exterior ply may not be pre-sanded and visually free of imperfections, it should still use 100% waterproof glue and be able to withstand long-term exposure to the elements.

What kind of plywood should I use for a boat floor?

Do you need to use marine plywood?

Marine-grade plywood may be required for homes or commercial buildings near the ocean, but you don’t need to buy the same level of water resistance as you would for a boat; if you buy the level you need but not more, you won’t compromise longevity but also won’t pay more than you need to.

How thick should plywood be on a boat floor?

Use a high-quality 1/2 to 5/8-inch plywood (I used 5/8-inch plywood). You should use a 24 to 36 grid pad to rough up the wood before applying fiberglass cloth to the bottom.

What is the difference between marine plywood and regular plywood?

In order to achieve the highest level of water resistance, marine-grade plywood uses hardwood veneers glued together with waterproof adhesive. In general, it’s a good combination of strength, light weight, and low defect count. Plywood with these characteristics is frequently used in the construction of boats and boat parts.
