I hope you can help with a problem I am having. I am hanging vinyl wallpaper on to a lined wall. Have used wall rock lining paper and beeline vinyl adhesive. Using same adhesive to hang a white vinyl wallpaper, Collani visions by Marburg. The problem I am having is when I have hung the paper I am getting a pale yellow discolouration/stain along the length of the butt joints. I am sure I am removing any excess paste. Would appreciate any suggestions or guidance that may help me to resolve this.
Thanks
Peter
