LePage 1601357 825ml PL 400 Subfloor & Deck Adhesive

LePage PL 400 is a professional subfloor and deck adhesive formulated for demanding framing work where squeaks, movement, and weather can ruin a job. Packaged in a large 825 mL cartridge, it lays a continuous bead that bonds plywood, OSB, and plank decking to joists and stringers and helps prevent nail-pop and panel lift. The low-VOC, toluene-free formula guns smoothly from -17°C to 49°C, so crews can keep working through cold mornings and hot afternoons without the adhesive “rolling up” on wet or frozen lumber. It also adheres to masonry, concrete, metal, drywall, plaster, brick, ceramic tile, and slate, making it a dependable construction adhesive for framing, sheathing, and general assembly. Because it can bridge minor gaps, PL 400 helps take up irregularities in joists and panels, improving contact and reducing rework on site. For new builds, renovations, and deck installations, this is a job-site staple for strong, reliable bonds.
