About This Material

Subfloor adhesive (PL400, Liquid Nails) is applied to floor joists before laying OSB panels to eliminate squeaky floors. Adhesive bonds significantly improve floor system stiffness.

Installation Tips

•Apply a continuous bead — do not dot the adhesive.
•Work in sections and lay panels before adhesive skins over.
•Use a caulk gun with a 1/4" nozzle.

Common Mistakes to Avoid
