We paid a highly recommended local woman to come strip the old wallpaper and hang new in our small bathroom this last Friday. On Saturday, we noticed that there are a few places around the room where there are hairline seams showing. These were not noticeable Friday night so it appears that the wallpaper has slightly shrunk. These are not big gaps but the wallpaper is much darker than the white wall behind it so they stick out a good bit.
Does anyone know if ...
1) anything can be done to fill these gaps? (soften paper and pull paper together?)
2) Is this something I should call the installer about?
I agree - call the installer about it.
It's too bad she didn't suggest it, but you could have painted the walls in the room a colour similar to the background colour of your paper. That way, if the paper shrunk (which if often does as it dries) you wouldn't have noticed the the seams as much.
