Lumberjack 30 Minute PU Wood Adhesive 310ml – Extended Open Time D4 Waterproof Polyurethane Adhesive

Lumberjack 30 Minute PU Wood Adhesive is a high-performance D4 waterproof polyurethane adhesive formulated for professional woodworking and construction applications. Offering an extended 30-minute open time, it provides extra working time for positioning, assembling and clamping larger or more complex projects while producing an exceptionally strong waterproof bond.

Supplied in a convenient 310ml cartridge, it is applied using a standard sealant gun for clean, controlled application. The polyurethane formula expands slightly during curing to fill minor gaps, ensuring maximum bond strength even where surfaces are not perfectly matched.
