Normally we need to fill plasterboard joints if we like to see a plain wall which is going to be painted...but what if we are planning to use wallpaper or plastic panelling?
What if we fill the gap (if any) between plasterboard with low expanding foam (sanding it) and then PVC on top (to prime the surface) and the wallpapering?
