When plasterboard is manufactured the gypsum core is formed by pouring rapid setting liquid gypsum in between an upper and lower layer of paper which is squeezed between rollers to form the different thicknesses of PB comes in.
So in effect it permeates the paper layers and as such it's characteristics are factory controlled and on site uses can be predicted.
When you tile onto 'wallpaper'.....what are you actually tiling onto..... a vinyl covered layer of wallpaper? ,a coat of paint covered wallpaper? and so on and so on.....
Quickest way to deal with wallpaper direct onto plasterboard is to remove the plasterboard! ,believe me, it's not as hard as you think.
