Paint over wallpaper, or remove??

LOL We once tried to paint over a supposedly well-attached wall paper on a bedroom ceiling with disastrous results. It seems the moisture in the paint was just enough to loosen the wall paper and gravity did the rest.

I’m a retired a painting contractor with over 20 years experience. The danger is that the wallpaper underneath will lift, causing bubbles.

And, as the previous poster says, there so much prep either way, why not do it right.

I’d opt for stripping the wallpaper, sanding the walls, priming and two coats of finish. It’s the right way to do it.

Break the steps into smaller projects if it makes it easier.

Short answer: it depends.

Best of luck.
