What is the best type of varnish or sealer to put on a refinished oak hardwood floor?
Please read my floor maintenance article available in the search box at the top of this web page. It mentions the 5 basic floor finish choices. And there is an article on the Dura Seal 1000 in that section of the site also.
But my choice for now is 3-4 coats of Fabulon Brand Pro Polyurethane Satin Finish, sometimes called heavy duty poly. I just finished coating my own floor with it an hour ago. They don’t have a web site, but here’s their # 800-263-8108. And I did find a supplier’s web site at http://www.whscott.com/fabulon.htm.
Oh, and except for the water based finishes, never use a sealer on hardwood floors, read my lacquer floor fires article, on this subject also available in the search box at the top of this web page.
