How long does PL Premium Polyurethane Construction Adhesive take to cure on Pine?

PL Premium Polyurethane Construction Adhesive takes 48 hours to fully cure on Pine at 70°F and 50% RH. Temperature and humidity significantly affect this — use the calculator on this page for an adjusted estimate at your actual conditions.

How do I prepare Pine before applying PL Premium Polyurethane Construction Adhesive?

End grain absorbs adhesive heavily — apply two thin coats with a 2-minute wait between to prevent a starved joint. Sand face grain to 120-grit. Do not use 220-grit or finer as it seals the fibers.
