Why is my polyurethane still tacky after 24 hours?

Oil based polyurethane “dries” in two stages. First the solvents evaporate leaving the resin behind. This normally takes on the order of hours, but as others have mentioned it depends on the temperature, humidity, and thickness of the finish. When the solvent has evaporated the finish will still be sticky.

How do you fix tacky polyurethane?

Try using a thinning agent like mineral spirits or paint thinner to remove some of the stickiness. This is a good thing to try especially when you’ve applied the polyurethane too thickly. To do this, dampen a rag with the thinner and gently wipe the surface. Wait a couple of days for it to dry.
