Hi! I need to put polystrene wallpeper abcking on two of the externeal walls in my kitchen. What's the best adhesive to use? Wallpaper paste? PVA?
In my opinion this stuff is a poor alternative to sorting out condensation and other problems. Use a border paste but check with the manufactures of the polystyrene. Alterativly use normal paste with a good slug of pva and fungicide solution. Paul
