I recently worked on a customers Walnut entry way here in Denver. The door was previously finished with a water based stain and varnish. He already had it refinished 3 times in the last 5 years by the same person who finished it in the first place and got tired of refinishing it almost yearly.
It’s no wonder that he had to refinish his wooden door so often if you use water based products outdoors. In my opinion these are made for interior use only. I used a high quality marine spar varnish to give this door a nice satin finish and a deep rich brown stain but see for yourself.
