Specifications

What it's used for

• Boat building and marine hull construction, where void-free cores and waterproof bonding are a structural requirement
• External joinery including doors, shutters, and window boards where the panel will be sealed and painted
• Wet-area interior fitouts such as bathrooms, utility rooms, and kitchen cabinets where moisture exposure is likely
• Outdoor furniture, planters, and covered garden structures where a durable, stable substrate is needed

Fitting and handling

Store sheets flat and off the ground in a dry, covered space before use. If moving panels from cold or damp storage into a warm interior, allow 24 to 48 hours for acclimatisation before cutting or fixing to reduce the risk of movement once installed. Fix using stainless steel or galvanised fasteners in external or wet applications, and always seal all cut edges with a suitable primer or end-grain sealer before finishing to maintain moisture resistance.

FAQ

What is the difference between BS1088 marine plywood and standard exterior plywood?

BS 1088 marine plywood is manufactured to a stricter standard than general exterior or WBP plywood. It requires void-free core veneers, tightly controlled face veneer quality, and waterproof adhesive throughout. Standard exterior plywood may contain core voids and uses lower-grade veneers, which can compromise structural integrity in demanding or wet conditions.

Does BS1088 marine plywood need to be treated or sealed before use outside?

Yes. While the adhesive bond is waterproof, the timber veneers themselves will absorb moisture and degrade if left unprotected. For external use, all faces and edges should be sealed with a suitable exterior primer, marine varnish, or paint system before installation and maintained regularly thereafter.

What thickness of marine plywood should I use for a boat hull or transom?

The correct thickness depends on the design specification for your build. As a general guide, 6mm is commonly used for lightweight interior panels and small craft hulls, 9mm and 12mm for cabin sides and sole boards, and 18mm for transoms, floors, and structural bulkheads. Always refer to your boat design drawings for confirmed scantlings.
