Q: I did a refinish and 3 coats of oil based polyurethane. I was wondering when I go to buff after the last coat 1) How long do I wait? and 2) Should I use a wax? What kind if so?
A: After the last, 3rd coat of oil based polyurethane you don’t buff again. You are finished. When the floor is dry you can carefully put furniture back in place. Don’t wax on top of polyurethane coatings.
