How can I remove difficult wallpaper?

I don't know about this, neither what your bathroom looks like... But I would certainly think about faux brick pannels or barnwood walls... Maybe both!

Home Depot is selling faux barnwood planks for a fraction of the price of real barnwood!

Good luck! :)

First off what type texture are you going for? I have taken wall plaster and just troweled it on the wall ,making swirls with the trowel. When plaster is dry, I painted with semi-gloss wall paint. Still on and still looks great....you might like that idea...no oil based primer needed.

Just make sure that whatever texture, etc you decide to use does not cause the wallpaper to bubble and peel from the moisture or you will have a mess on your hands. Have you tried scoring the wallpaper with a little roller called a wallpaper tiger? Then, spray the paper with warm water and wipe it with a damp sponge to soak the water into the paper....then peel it off. Usually this method works pretty well.

Yeah I would do the work to remove the old wallpaper, you can't be sure it won't lift from the moisture in the bathroom, and then its going to be twice as hard to remove. Rent a steamer from a tool rental place, and douse with fabric softner after you score it. Then put your steamer on it, and after a few minutes see if it will budge. If not steam some more.

Use 1/2 water 1/2 clothes softener into a spray bottle...score the wallpaper and already the softener solution...wait about 20 minutes and start peeling off the wall paper

diff or soapy water and Spray n let sit peel off before starts drying

spray with a light oil and like soak in overnite, it will loosen the glue and you should be able to scrape off.

any oil olive oil works a bit messy

I have never had much luck with DIF, but some people swear by it. I always use either plain water, or plain water with a bit of vinegar added. Sometimes, for really stubborn paper, if you warm the water up a bit, it will help dissolve the wallpaper flue. Good luck to you!
