What is the difference between marine grade plywood and treated plywood?
Marine plywood is specifically manufactured to stand up to the harsh marine environment. The materials used in in its construction are specifically chosen to assist in making it as water resistant as possible. Pressure treated plywood is usually regular softwood and will absorb moisture very easily.
What is special about marine grade plywood?
It is a good-quality, hardwood plywood made with waterproof glue, but since it’s not treated with chemicals, it is not rot-resistant. Better grades also tend to be lightweight, strong, and virtually free of defects. These qualities are what make this plywood a popular choice for building boats and boat parts.
What is the difference between marine grade plywood and regular plywood?
Marine-grade plywood is a sturdier, higher-quality material made of Western Larch or Douglas-fir that is not treated with chemicals. However, heat and pressure are also essential to arranging Marine-grade plies, as this type of wood is not naturally resistant to rot and decay (unlike some types of lumber).
Is Far Eastern marine ply any good?
It is excellent hardwood plywood engineered with waterproof glue. This plywood is not chemically treated; therefore, it is not resistant to rot. Marine plywood has good grades, are robust, lightweight and defect-free.
Is marine plywood void free?
Marine plywood is a type of hardwood plywood. Plywood sold as “void-free” does not have voids hidden in the wood layers. As for the layers, a lot of thin layers is better than fewer thicker layers because thinner results in a stronger, denser panel with edges that cut and sand cleaner.

It is considered a “premium” panel grade for use in situations where these characteristics are required. It is available in 4×8-foot sheets of 1/4, 3/8, 1/2, 5/8 and 3/4-inch thickness. Marine Grade Plywood is not treated with any chemicals to enhance its resistance to decay.
What kind of plywood do you use to build a boat?
Basic Exterior-type plywood may be used for most other applications in boat construction. Plywood panels rated as Exterior but not Marine, such as A-B, A-A or C-C Exterior, may contain any other permissible species and contain C-grade veneer.
What is a C grade plywood panel?
Plywood panels rated as Exterior but not Marine, such as A-B, A-A or C-C Exterior, may contain any other permissible species and contain C-grade veneer. Unless specially improved, C-grade veneer is permitted to contain knots and knotholes up to approximately 1-1/2 inches across, and the inner plies may have core gaps up to 1-inch wide.
What sizes do plywood sheets come in?
All plywood is sold in full sheets. Plywood sheets are 4′ x 8′. Prices are per square foot of coverage 3/4″ thick and 5 1/8″ face width. These materials must be special ordered or milled, so allow two weeks for delivery. Some material is available in other widths. Also, T&G V-joint is available in most species.
