In my living room, there is plaster on three walls. The plaster is quite wavy with relatively large level differences (1-2 cm). The walls together with a few arches give a clear feeling of a pizzeria... We will remove the arches and replace the plaster with wallpaper. The question is how I should do this practically? The house has aerated concrete walls under the plaster. Is there any stratification that I could use to simply hack it down...
