Frequently Asked Questions

What thickness of hardwood plywood is suitable for my project?

When determining the appropriate hardwood plywood thickness, it is essential to consider the specific application to ensure optimal performance.

For intricate crafts and hobby projects, a thinner option like 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, choose between 9mm or 12mm plywood, depending on the specific load-bearing requirements. In applications where durability is paramount, such as flooring, subfloors, or heavy-duty uses, it is advisable to opt for a sturdier option, like 18mm plywood.

Is marine plywood waterproof?

While marine plywood is not entirely waterproof, it features a negligible core gap to minimise the likelihood of water getting trapped between the layers. This design ensures a strong and stable glue bond, providing extra strength.

How does marine plywood differ from regular plywood?

In comparison to standard plywood, marine plywood utilizes higher quality wood, incorporates more layers, employs a more durable adhesive, and is specifically designed to resist delamination and warping when exposed to moisture over time. Regular plywood is not suitable for prolonged wet conditions.

What is the recommended method for sealing marine plywood?

Given that marine plywood is often used in or around water, it's crucial to treat every surface with a sealant. A waterproof penetrating epoxy is ideal, as it penetrates deep into the wood, dries transparent, and requires less maintenance than other sealants.

Do I need marine-grade plywood?

We recommend using marine-grade plywood in any instance where the sheet will be near water.

How long does marine plywood last?

With proper maintenance, marine plywood can last over 25 years, even with constant water exposure. Sealing and painting contribute to extending its lifespan.

Is marine plywood treated with chemicals?

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