About two years ago, I repapered a room in my house with a textured paper intending to paint it. For various reasons, I didn't paint it until 6 months later. The paper has now started to come away from the wall in various places, mostly either side of a few joins on walls and ceiling. I've tried working a pva glue behind the paper on either side of the joins, but the paper is so stiff from being painted it will not stick back to the plaster. Can anyone suggest a way of sticking the paper back? Also, where the paper is loose away from the joins, I was wondering if I could use something like a hyperdermic needle to squirt glue behind it? Any ideas anyone?
I'll be grateful for any suggestions. Thanks
