It’s hard to put my finger on exactly why.


It also doesn’t help that there is a lot of lint and other stuff stuck in the paint, creating a gritty and uneven wall surface.
Oh, and the texture that was rolled on is irregular and icky.

And note the ridge along the top of the baseboard. Can’t expect wallpaper to grab ahold and adhere to that.

And finally I figured out what was causing a large part of the problem … The room had been wallpapered previously. So when it was decided to paint the room, instead of stripping off the paper as they should have, they just painted over it. To me, it looks like there are several layers of thick latex paint on top of the wallpaper.

As you can see, the latex paint is not adhering tightly to the old wallpaper. The wallpaper looks like it could be vinyl … and not much sticks well to vinyl. Think Colorforms.
Stripping off all this paint and the wallpaper under it would make a HUGE mess. So, short of re-drywalling the whole room (and the rest of the house, which has the same treatment), there’s not much that can be done to ensure that the layers inside this wall are stable.
I dug out caulk and pulled off any loose areas. Then I skim-floated the whole room to create a new, smooth layer on top. I’ll post more when that process is finished and the new wallpaper is up.
