We just let a painter convince us that itls OK to paint over wallpaper and now I regret it. It was primed first but it doesn't look good at all. There are some places where the paper seperated from the wall and it just doesn't look right. He said he could fix it but if not, it all comes down. Also, you can see the seams and if you have to go through all that trouble to hide them , you might as well take it down. I sure wish I did.
