LP Legacy Premium Sub-Flooring Adhesive is designed to work in tandem with LP Legacy Premium Sub-Flooring and LP TopNotch 350 Durable Sub-Flooring to create tight seals in small gaps between panels, helping produce a still, squeak-free subfloor system. LP says the gun-applied polyurethane collapsible foam adhesive is fast-curing, 100% solvent-free, and VOC-compliant, and one 29-ounce can provides 12 times the coverage of a typical tube of subflooring adhesive. The adhesive can be applied to wet, dry, or frozen lumber, treated lumber, masonry, decking, concrete, or metal. lpcorp.com
