My daughter wants to have one wall of her Georgian flat papered. This wall has previously been papered with a very lightly mottled paper and emulsioned to my certain knowledge with at least three coats of matt emulsion. I would guess that the original wall in this Hove flat would be lathe and plaster. The current emulsioned condition and appearance of the wall is good with no apparent obvious defects. We cannot contemplate removing the existing emulsion covered paper with all the problems that might entail. Can anyone please offer advice as to whether we should be able to successfully paper over the existing paper and whether the wall should be sized and allowed to dry. Also if the instructions with the new wallpaper state that the paste should be applied to the wall with the paper being applied directly from the roll is this the best course of action? ie the paste not being applied to the paper prior to hanging.
Any and as much advice as possible would be much appreciated.
