For both our non woven wallpaper and MuralTex you always apply the glue to the wall, not the wallpaper. Make sure the glue is evenly and properly spread over the wall and always use glue suitable for the type of wallpaper you ordered. Also ensure that the strips align nicely with non woven wallpaper to avoid gaps and achieve a smooth and perfect result.
For self adhesive wallpaper Peel and Stick no glue is needed. Thanks to the adhesive layer on the back you can start sticking immediately.
