Q: Can polyurethane be used over a section of my oak floor that was finished with Waterlox?
It has three coats of Waterlox which were applied two weeks ago and are totally dry. This was a heating grate area that we filled in, as the heating system has been totally changed. The surrounding floor has polyurethane finish.
So can I add polyurethane over the Waterlox?
A: Yes you can use polyurethane over Waterlox. I would give it a bit of a scuff with fine sand paper, clean and coat.
