The GAF 0946 36 Inch Dry-In Membrane Roll can be applied directly to plywood, OSB (oriented strand board), and wood plank (non-chamfered edge) decks. It is important to note that the membrane should not be applied directly to wood plank roof decks with high concentrations of resin or "pitch" that can naturally bleed out of wood boards, particularly new soft woods (e.g., pine, spruce, larch, or Douglas fir). Direct contact between the leak barrier and wood planks may cause deterioration of the leak barrier. It is recommended to consult the product manual and exercise caution when applying the membrane to wood plank roof decks.
