What is Marine Plywood?

Marine plywood (marine ply) is a plywood particularly well suited for wet or humid areas, and is considered to be the best plywood for outdoor applications. Our marine grade plywood is manufactured using durable face and core veneers. Designed to have minimal defects, our marine plywood sheets resist both delamination and fungal attack. This material is especially suited for use in the ship and boat building industries.

Marine Plywood cut to size

Each sheet of marine plywood can be cut to any custom size or shape. This saves you the hassle of having to trim the piece down yourself.

Marine Plywood thickness

As with our other plywood and MDF products, our marine plywood sheets are available in a range of thicknesses. These include: 6mm, 9mm, 12mm, 18mm.

When choosing your marine plywood thickness, consider how the material is going to be used in your project. Thicker sheets are more robust and will have stronger load-bearing capabilities, while thinner sheets are lightweight and better suited for facings.

Marine Plywood FAQs

What is the difference between marine plywood and exterior plywood?

Both marine plywood and exterior hardwood are robust materials suited for outdoor use, harsh weather, and damp. The key difference between marine and exterior plywood is the material used. Marine plywood must adhere to stricter standards than other types of plywood. This applies to both the glue and the wood used in its manufacture. Marine grade plywood is manufactured using more permanent and weather-resistant glues than other types of plywood. The wood used for marine plywood sheets must be defect-free, high-density hardwood.

The lack of defects ensures a smooth surface that will be more water resistant and hardwearing. Other types of plywood have looser restrictions on wood type. All of these differences mean that marine grade plywood is the most robust and water-resistant option on the market.

How long does Marine Plywood last?

Marine plywood can last anywhere between 15-25 years depending on the application, quality, and exposure. When using marine grade plywood in your projects, ensure that you follow all recommended instructions of installing and sealing to ensure maximum longevity.

How strong is Marine Plywood?

Marine plywood is stronger than other types of plywood and will maintain its strength if it gets damp.

Is Marine Plywood waterproof?

Marine plywood is water resistant, but not waterproof. While it might be made with waterproof glues, the wood itself does not undergo any special treatments. As a result, marine plywood is not truly waterproof.
