Evening, My wife and I recently bought our house and as it had a lot of imperfections and holes, we decided to line the walls before painting. So far, we have had problems with bubbling, the edges lifting and overall, not looking great. We filled and sanded the holes first then used a 1200 grade lining paper along with paste the paper. We pasted then left for 5 minutes to soak. It has still come up at the edges and bubbled. Having painted over the top, it still looks rubbish. We would really appreciate any advice as we’re really stuck why it’s not working. I have uploaded photos for you to see what I mean.
