18mm Marine Plywood Complies With BS1088

This 18mm BS1088 marine plywood is designed for boat builders and coastal installers, delivering reliable moisture resistance and lasting panel integrity.

Made from premium tropical hardwood veneers in a robust multi-ply construction, it resists moisture ingress and delamination, even in external, marine and high-humidity environments.

The Weather Boil Proof adhesive seals each core, delivering a durable WBP bond and gap-free cores that minimise end checks and protect panel integrity.

Available in sheet sizes up to 8x4 ft, it's ideal for boat building, coastal installations and frameworks where performance matters.

Practical tip: keep panels dry before cutting, seal edges and store flat to protect the Weather Boil Proof joints.

This plywood outperforms standard exterior grades in salt spray, making it a practical choice for hull frames, decks and high-humidity joinery.
