Important Product Information

This 9mm plywood is suitable for exterior use only when all edges and faces are properly sealed to prevent moisture ingress and degradation. As with all exterior-grade plywood, sealing after cutting is essential for long‑term performance. It is ideal for uses such as shed walls and roofs, hoardings, cladding, and general outdoor sheathing, but not intended as a full marine‑grade replacement.

Please note: Timber is a natural product. Finish, colour and sizes may vary from illustration and description. While every care is taken to provide you the best material, with it being natural it can move, split, warp, twist, swell and shrink.
