Printed on WallSmart wallpaper (non-woven fleece). WallSmart wallpaper is a new generation of non-woven wallpaper that is easier and faster to hang. When hanging the wallpaper, apply the ready-mixed wallpaper paste to the wall and than hang the sections by butting the edges tightly together. For the best result, we advise you to buy enough wallpaper in the same order. As the colours are blended by hand on each print run, there may be slight colour differences between the different batches. We make sure that rolls of wallpaper ordered at the same time have the same batch numbers.
