9mm Marine Plywood Sheets

Details

A tough and hard-wearing material that can be used in external applications, marine plywood is designed to perform for long periods in humid or wet conditions. 9mm marine plywood can be used for a wide variety of applications, from walls and roofing to storage boxes and indoor vehicle buildings. This plywood resists fungal attacks and delamination so it’s ideal for use in climates and environments that are prone to moisture. We can provide 9mm marine plywood in any size or shape you require, and we offer quick delivery so you can use your products as soon as possible.

The type of marine ply we offer has a high-quality BB/BB face grade and is well-suited to demanding environments such as gardens, bathrooms and parks as well as for roof supports and advertising panels where it needs to withstand harsh elements. 

Key Features

A big benefit of using marine plywood sheets is that it’s easy to machine and work with, as it has a great strength-to-weight ratio. It can be cut to size easily with just a handsaw or an electric saw, so it’s great for DIY projects. This wood can also be varnished or painted easily as it has a great surface that’s smooth and free from knots. Most woods don’t cope well with water or moisture, which can lead to rotting and warping, and lower the integrity of the structure. By using marine plywood, you can ensure that the application will remain strong and sturdy for a long period of time.

The versatility of marine-grade plywood is a huge advantage of this material. It can be used for such a wide variety of projects, from garages and sheds as a construction material to walkways where it’s expected that the wood will come into contact with moisture. Marine plywood is also a pliable wood that can be bent into shape without it losing its structural integrity, which provides an added layer of versatility. This wood provides excellent value for money without compromising on quality. It’s resistant to cracking, warping and twisting, and also minimises splitting when screws or nails are used. Our other most popular sizes are 12mm marine plywood and 18mm marine plywood.

Applications

9mm marine plywood is a great option for use in joinery in areas where moisture is common. The thinner variety of marine plywood is ideally suited to van or trailer linings as well as for cold storage containers, packing cases or for boxing in pipes and wiring. It can be used to great effect in temporary structures or for concrete frameworks. Marine plywood can be used for signage as well, as it can be painted or stained well and can cope with outdoor environments as well as indoor signs, whether it’s for door signs, branding or directional signage. We also offer birch plywood, hardwood plywood and softwood plywood.

Frequently Asked Questions

What thickness of plywood do I need?

When deciding on the appropriate hardwood plywood thickness, consider the specific application to ensure optimal performance.

• For intricate crafts and hobby projects, a thinner option, such as 4mm plywood, is well-suited.
• If you're working on cabinet backs, a 6mm plywood sheet provides the necessary stability.
• For furniture construction and shelving projects, opt for either 9mm or 12mm plywood, depending on the specific load-bearing requirements.
• When durability is paramount, especially in applications like flooring, subfloors, or heavy-duty uses, it is advisable to select a sturdier option such as 18mm plywood.

Is marine plywood waterproof?

Marine plywood is not waterproof, however, it has a negligible core gap so that the likelihood of water getting trapped between the layers is minimised. This provides a strong and stable glue bond for extra strength.

How is marine plywood different from regular plywood?

Compared to standard plywood, marine plywood uses higher quality wood, more layers, has a more durable adhesive, and is designed to resist delaminating and warping when exposed to moisture over time. Regular plywood is not suitable for prolonged wet conditions.

What is the best way to seal marine plywood?

Since marine plywood is typically used around or in water, you’ll need to treat every surface of the wood with sealant. You can find a good waterproof penetrating epoxy to be ideal as it works deep into the wood, dries transparent, and requires less maintenance than other types of sealant.

Do you need marine-grade plywood?

We recommend marine-grade plywood around any instance where your sheet is going to be near water.

How long does marine plywood last?

When properly maintained, marine plywood can last over 25 years even with constant water exposure. Also, proper sealing and painting helps to extend its lifespan.

Is marine plywood treated with chemicals?

No, marine plywood is not chemically treated. It achieves its water resistance through the use of durable face and core veneers, resistant adhesives, and multiple laminated layers.
