I have been helping my daughter all weekend to line heavy duty lining paper on a bedroom wall, of an old house after she removed 4 layers of old paper and paint which left the walls looking a mess. However the lining paper, now we have painted it all, is starting to peel away at the joints and we can see all of the lines in the paper. We were careful not to overlap and in some places left a small space where walls ran out. How can we stick the paper back down to the wall as paste does not seem to be strong enough? And how can we then get rid of the joint lines?
