Having tried several of the above methods to strip layers of wallpaper in our 5400 sf/160
yr-old house, I highly recommend using a Wagner 705 power steamer. You should be able to find a good used model on eBay for under $50 including s/h, & can always sell it when you're finished. The 'paper tiger' is the tool referred to above, but you won't need one with the steamer--unless the paper has been painted & won't allow the steam to penetrate.
I'd like to express my appreciate for the opportunity to be involved on this website. While I am a Pro, I am not a Pro at everything .. but often times have an opinion like everyone
else! *grin* What I think is a bonus/value that I was not anticipating is learning MYSELF from the questions posed and the other Pros that are here to answer. YeahH! Glad to be here .. love learning from others and very much appreciate the diverse opinions and ideas shared here!
