I have laid laminate flooring in the kitchen and will continue into the hallway. I realize I will have a 13mm gap, and it doesn't seem like it will hold if I cut the floor so narrow. The alternative is to put up a 13mm plasterboard. The wall behind is lightweight concrete with 3-4 layers of wallpaper.
How do I attach the board easily without removing the wallpaper, as it is holding well? I read on some different tubes at the hardware store and thought that PL600 might work. But at home, I started to have doubts. Tips?
