We have a variety of different plywood sheet types to choose from which we can cut to any size or shape using our CNC router for a greater level of accuracy and repeatability. Whatever shape you have in mind, we can cut it – just send us your drawings, in either CAD or a sketch format, and we can create it for you. In addition to our ability to cut any shape or curve to plywood, our CNC router can be used for rebating, pocketing and hole cutting on virtually any sheet material. We also provide the option of laser cutting, CNC engraving services to your plywood sheets as well.

Using state-of-the-art UV printers, we can print full sheets of plywood in one go, providing a professional finish at a much faster turnaround time than painting. We currently only list 8x4 sheets (2440x1220mm) but we’re able to purchase and cut sheets of up to 2000x3000mm. Get in touch with our team today to discuss your specific requirements.

18mm Marine Plywood Grades

Wood comes in a variety of grades; we offer the grades listed below. See our plywood grading guide for more information on the types available.

Marine plywood is for use in environments where the wood is exposed to moisture for extended periods. The type of wood 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.

Advantages of 18mm Marine Plywood

Marine plywood is a great wood to work with, with a smooth and knot-free surface that’s ideally suited to staining, painting and lacquering for a professional finish. This variety of plywood provides a high-quality finish at a more affordable price and is durable enough to ensure that whatever application it is used for will stand the test of time. The process of producing marine plywood minimises the risk of water and moisture getting trapped within the layers of the plywood, which reduces the risk of rotting and delamination. This provides a hard-wearing wood that can cope more effectively in humid and wet conditions without losing structural integrity.

18mm marine plywood delivers excellent versatility and is suitable for a wide range of applications and environments, from interior projects such as in bathrooms or areas where moisture is present, to external applications such as sheds and walkways. It’s easy to work with, as it can be bent into shape without cracking, and can be screwed or nailed into place without splintering. The pliability of marine plywood makes it a more adaptable material compared to standard plywood sheeting. The thickness of this particular plywood makes it more sturdy in areas where weather conditions make ordinary woods susceptible to bending or warping, delivering a more secure final product that will remain in place for long periods of time.

Applications of 18mm Marine Plywood

18mm marine plywood is commonly used for shop fitting and roofing, as well as for floors, boarding up shop fronts or windows, and for wall sheathing. The thickness of this plywood also makes it ideal for exhibition stands, racking and for packaging and storage containers, providing security and stability. 18mm marine plywood is well-suited to site hoarding, as it can cope with various weather conditions such as wind and rain without deteriorating, plus it’s thick enough not to crack or split when exposed to high winds.

Frequently Asked Questions about Marine 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.

What is special about marine plywood?

Marine plywood is special as it prevents water from getting trapped between the layers of the real wood veneers. As such it creates a sheet that is more water-resistant than normal plywood and is ideal for those intending on utilising it around water.

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 much is marine plywood?

Our marine plywood ranges in price from £62 per square metre to £150 depending on thickness. This does not include any cutouts, drilled holes or any additional means of alterations.

Can you paint plywood?

You can paint plywood, but be sure to use primer, as plywood will absorb more paint than you would expect so the primer seals the plywood, and allows it to take to the paint more easily keeping your surface smooth and sealed.

Can you bend plywood?

It is possible to bend plywood. There are numerous ways of bending plywood, but if you are after a sheet that cannot be bent, look at our MDF sheeting.

What is plywood used for?

Plywood can be used for a wide range of versatile structural applications whether interior or exterior, from furniture to internal panelling.

How strong is plywood?

Plywood is relatively strong as it is numerous layers of wood pressed together. For a stronger piece of plywood, look for 5-ply or multi-ply sheets as these will have more layers, and thus more strength.

What are the types of plywood?

We sell a variety of types of plywood, including softwoodhardwood, marine, and birch, all of which have specific characteristics and will aid specific projects. For more information on the respected types, read their descriptions at the bottom of their product pages.

Can I cut plywood?

It is possible to cut plywood yourself, but we are able to do it for you if you request at the point of ordering. To do so yourself please follow safety procedures, and use a sharp saw else you risk the sheet breaking.

How is plywood made?

Plywood is made by glueing a series of thin veneered sheets of wood together. Each adjacent layer is rotated by up to 90 degrees to reduce the risk of splitting when nailed in at the edges. This technique, referred to as cross-grain, improves strength, stability and prevents warping, making it an excellent general-purpose construction panel.

How do you seal plywood edges?

Plywood should be sealed to prevent moisture from affecting the sheets and causing warping. The sealant you use will depend based on how you intend to use the plywood, but you should use something quick-drying and can withstand all temperatures, and be compatible with paint if you intend to paint your plywood.
