Hand applying polyurethane glue to a wood joint with a wooden stick in a workshop setting.

Begin by lightly dampening the wood with a spray bottle. This opens up the pores of the wood and speeds the curing of the glue. Spread a moderate amount of glue into the joint. (This stuff foams to three times its original volume).
