OSI SF450+ Polyurethane subfloor adhesive is a one component, polyurethane based, moisture-curing adhesive. It offers superior adhesion to most building substrates, providing 2X strength than normal subfloor adhesives. When using the pre-cut 1/4 in nozzle, it provides twice the coverage. SF450+ Polyurethane forms a permanent durable bond even when applied to wet, frozen or treated lumber. This low-VOC formulation can be used for both interior and exterior jobs and meets stringent State and Federal VOC regulations.
