Hardwood Plywood | B/BB Grade WBP Exterior Plywood (18mm) - Product Video
Specifications
Our 18mm Hardwood Plywood is made up of 3 or more thin layers of wood veneer laid on top of each other and glued with the grain of each segment. This particular type of Plywood is praised for its numerous strength qualities, including durability, stability and a high level of impact resistance. These boards also possess a number of damage resistant qualities, giving a long lasting and high quality finish to your project. The boards are extremely resistant to wear and any moisture damage due to their WBP Grading, along with having incredible hardiness against splitting and breaking when working with them.
Due to this, Hardwood Plywood is extremely versatile, its uses include; bath panelling, sheds, storage boxes, roofing, interior vehicle building, floors, walls and roofs in house constructions. This Plywood is B/BB Graded, so it already has a great surface finish, but can be varnished or painted if you require a different finish.
NOTE: Due to receiving stock from different suppliers, the grade can vary. Please contact us prior purchasing if you are wishing to use the ply externally. We do advise to seal the board for better moisture resistance when the board is used externally.
