Q: White pine floor, 3 coats of poly… The last coat has not hardened, and it has been almost two weeks. It’s dry on top, but the poly is still soft. When you turn your foot on it tears up. Should it take that long or longer to harden? What if I heat the room for a few days?
It has been 60-75 degrees during the day and 35-55 at night for the last 2 weeks.
A: Oh my! How do you expect the finish to dry in those temperatures? Did you read the label? If you applied all coats at these temperatures, you can expect a tender coat for some time. You will have to wait it out and put some heat in the rooms. You should have 70F or more per coat for at least a month to cure.
