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.
Roseburg’s DuraGard Premium MDO plywood is the perfect, paint ready industrial plywood panel. Its very smooth paper overlay receives paint excellent with less drip and minimal if any grain transfer. The western softwood core is very stiff, strong and durable and will provide years of service if maintained properly. The smooth resin (water resistant phenolic) impregnated cellulose fiber overlay is available one 1 or 2 sides and DuarGard Premium can also be ordered factory primed on 1 side or 2 sides.
Roseburg’s DuraGard is made with a high-quality paper saturated with phenolic resin solids and overlaid on our exterior-grade plywood panels. The “B” Plugged Fir veneer beneath the overlay provides a smooth surface ideal for painting. DuraGard is manufactured with waterproof resins that meet or exceed all veneer-grade, adhesion, and construction requirements of PS 1-09.
Because DuraGard Premium is usually finished, it is important to keep the product dry before use. Roseburg recommends storing DuraGard Premium in a warehouse or under roof. If stored outdoors, units should be covered loosely with a protective material.
