About 6 months ago I lined the walls of our spare bedroom with lining paper and painted with matt emulsion. After a few weeks I noticed the joins between the paper on one of the interior walls (partition type) were opening up. I duly filled them and repainted. However, they keep reappearing. Every
4 weeks or so I have to fill and paint. The gaps are only about 1/2 mm, but are very noticeable. Any ideas what is going on and how to stop the gaps opening up?Thanks
