I'm not sure if the OP is reading this anymore, but I did want to offer advice. I've been scraping (and scraping and scraping, you get the idea) wallpaper for so long. We're in the process of redoing my daughter's room and there were many many layers of wallpaper on the walls. I assumed the layers started in the 1930's, but on one wall, they put sheetrock over the plasterwall. It's some bizarre cardboard-like substance, so I guess in the 1950's- late 60's they just redecorated a lot. Anyway, long story shortened, when I got to the last layer on that cardbaord wall, it's stuck like glue over it. I got off all I could, scrubbed it, and my husband put a layer of plaster over the whole thing and it's now smooth as glass. I don't think this would work with many many layers, but my father in law has done this in the past, and after 20 years all is still good. I wouldn't recommend doing this in the more public areas of the home, but in the bedrooms it might work for you. It sounds like from your post that you are a thoughtful remodeler. I, like so many on this forum, cringe when thinking of "flippers" and the lack of care for history that many have. However, there are people who remodel who do a great job and do it not only to make money, but to improve their community. Those people are to be commended, because their vision helps create a longer history for that house in that community. I hope that you are able to bring that home to its former glory and find a family to love it.

I agree w/prev poster, do a small single room first and see what shape your wall are in. Not worth stripping if you'll have to replace or skim coat anyways. Re stripping, here's what worked for me: Get on of these scrapers... http://ace.imageg.net/graphics/product_images/pACE2-960411reg.jpg Get some FAST wallpaper remover (I like better than DIF)... http://www.cornerhardware.com/images/18/18151.jpg Mix the FAST w/hot water in a good heavy duty spray bottle. Mix it a little on the strong side. Let the spray penetrate for a few seconds, then scrape. When you have all the old wallpaper off, you can wash the walls with a mild FAST solution to get all the glue off. Then wash again with something like Dirtex... http://www.cornerhardware.com/images/20/20293.jpg Because of the paint you may have use a paper tiger to score the paint and wallpaper to allow solutions to penetrate... http://www.homeandbeyond.com/dynamic/prod-0074110-prod.jpg Or if it's real bad, maybe a rent a steamer.

Yes. However, I would not rely on Aura to self prime over non-porous wallpaper. After washing the walls, prime with Zinsser BIN and let dry. Then coat any seams with your preferred mud or spackle. Get it smooth to your satisfaction by lightly sanding it with a wet sponge. Prime over the mud or spackle and let dry. Then two coats of Aura. DO NOT MUD PRIOR TO PRIMER. IT WILL NOT ADHERE TO THE VINYL COATED PAPER. Michael

The more time I spend here....the more I can understand why the average consumer is completely confused. It's not your fault (consumer). It's just because there are so many people who proclaim so loudly and boldly their "opinions". They must be right....right? They are "professionals". This is what they do for a living...right? The one truth about the internet is that everyone is 10 feet tall, bulletproof, successful, beautiful, and amazingly intelligent. Who would have ever guessed the power that anonymity and a keyboard could create? I can read the side of a paint can just as well as the next person. If it says it....it must be true....right? Maybe that's why I currently cook every meal with the Magic Bullet...use Oxy Clean daily...the Swivel Sweeper cleans my floors...magic Asian foot pads keep me healthy...which allows me the time to be the next "no money down" real estate millionare.....you'll see. What really matters most to you, pamies, is your project and what you want to achieve. The bad news is that there are several opinions...even more on the web. That's why you are confused (rightfully so). The GOOD news (and isn't that what matters most?) is that with the shape your walls are in (already having wallpaper over them) you can take any one of the offered suggestions and, at the end of the day, you simply won't have a problem. Kilz...not really the best idea only because it's oil base and a pain to work with. Would it work? Probably so. Gardz...not really meant for the job...could "fish eye" if the old paper is vinyl coated...but will actually dry to a film regardless. Would it work? Probably so. Acrylic primer...will wet the surface and then dry to a film. Would it work? Probably so. The bottom line to you is to not get caught up in a confusion of self proclaimed experts (yes...that means me too). You just want your bathroom done and looking good. With the shape it's in...and the fact that the pressure of a top layer of wallpaper caused no failure...you can paint (prime) that space with just about anything and pull off a successful paint job. Don't stress too much, pick something...anything, knock it out and paint it the way you want to see it. Then relax and enjoy it.
