I posted this question early this week and haven’t received any feedback. At the time, for some reason, I could not send it directly to you, the finishing expert, so I sent my question to “assign and expert for me.” Maybe you can help me.
I am installing a custom made (by me) solid wood exterior door. It is made of traditional frame and panel construction, is 1 3/4″ thick, and is made of quarter sawn burr oak. The door is on the front of my house, which faces north so it never gets direct sunlight, and it is sheltered from direct rain. I live in St. Louis, which has four extreme seasons, including high humidity in the summer and below freezing temps in the winter.
I have built this replacement door because the old door, which I commissioned an ex-acquaintence to build for me five years ago for my new house, warped almost two inches. That’s right, two inches. I planed and sanded and adjusted it and the thing never worked right, and I wasn’t able to even use it all this summer. Besides the faulty construction, I think it was mainly the humidity that ruined that door.
What would be the best finish I can put on my new door to keep it stable in all temperature and humidity extremes?
