I'm getting ready to refinish the wainscoating in my living room and dining room, which, if it follows the fashion of the day (1915), should be oak. The floors are maple/curly maple. In my childhood, I remember there being large ceiling beams and these were covered by tiles in the late 1950's. I want to remove the tiles and refinish these beams. Has anyone else taken on such a project and what hazards should I be aware of first?
