Machining & Fastening

Roseburg’s DuraGard Premium can be sawn, nailed, routed, shaped and drilled. Always use sharp, high-speed tools and take care to avoid marring the overlay surface. DuraGard Premium should be securely fastened with 6d nails on 3/8” and 1/2” panels and with 8d nails on 5/8” and 3/4” panels. Space. nails 6” o.c. around all panel edges and 12” o.c. at intermediate supports. Nails should penetrate at least 1 inch into the substrate material. Leave a 1/16” gap between panel edges. Spiral or ringshank nails offer the best holding power, but screws and bolts can also be used.


DuraGard Premium should always be painted when exposed to weather or humid conditions. It is recommended that a primer coat produced by the same manufacturer as the finish coat is applied and follow the manufacturer’s specific application recommendations. Panels must be dry when applying the finish. Panels intended for exterior exposure should be edge sealed with two heavy coats of top-quality exterior paint formulated for wood. Edges are most easily sealed when panels are in a stack. Roseburg offers factory priming on one side, two sides, and edge.


DuraGard Premium plywood is stronger, more rigid, and less subject to creep than composition products. The core innerplies and back are all “C” grade or better as outlined in PS 1. A layer of hardwood veneer completes the core construction and provides a smooth surface for bonding the phenolic) impregnated cellulose fiber overlay.
