Before fixing, acclimatise boards to the site. Then allow the correct expansion gaps at edges. For visible areas, sand lightly and apply paint or clear coats as required. If the area sees regular moisture, seal edges after cutting.
OSB Smartply full board is a practical choice for structural and utility projects such as roof decking, flooring, wall sheathing, hoarding and storage builds. Its oriented strand structure gives reliable strength and stability at a cost-effective price.
Plywood is often preferred when a smoother face, decorative finish or layered plywood edge is needed. Choose OSB Smartply for practical construction and site work. Choose plywood when appearance, decorative finishing or plywood-specific performance is more important.
If you need a smoother face or cleaner decorative finish, compare this with our birch plywood full board.
