Yep as suggested solvite is all you need.Most UK wallpaper is hung with powder based adhesives.In fact if you are hanging a pulp paper(as many UK wallpapers are) using a pva based adhesive can give you real issues because pulps needs to be soaked,a pva based adhesive retards this which means it can blister once hung,not normally a big issue but if you have used a pva based product the blisters won't dry back(big problem).
In the UK at least wallpapering is now virtually only being used for feature walls.Poor quality cheap wallpapers using crap lining paper on back(most pulp wallpapers are duplex e.g the pattern is on one layer of paper which is stuck to another,if the backing paper is not treated ,and most aren't,you get edge curl,and it's pain to sort) means people don't really trust wallpaper manufacturers any more.
