Hi I am wallpapering the long wall of a stair well of a bungalow with a dormer floor. The wallpaper is currently varnished but cracked where the wall material underneath changes from skimmed walls to hardwood walls upstairs. The old people that own it don't want me to take down the wallpaper that is currently there in case the walls fall down, but I am pretty sure that if I fill the cracked areas I can wallpaper over the top. In order for the wallpaper to take, I am guessing that the best thing would be to pva the wall first. If so, how diluted should the pva be or are there any other things I should do to prepare the old wallpaper for the new wallpaper?
Any help would be gratefully appreciated.
Thanks
Annie
