Sounds like an old stain so should be fine, just spray some stain block on it first, let it dry then its good to go. George.
Signs of damp...

I am about to wallpaper a wall and have been aware of water marks on the wall... Despite ridiculous deluge (recently and over past 2 years), the water damage hasn't worsened or changed... CAN I therefore assume that it's old damage (before my time at the property) and that I can simply wallpaper over it?

hello. good answer by richard the other way ive found that is a bit cheaper is to use a p.v.a.glue mixture to seal the wall prior to papering.

Hi Anthony. Yes it sounds like an historic leak which has left a damp stain. Probably a good idea to stain block it either using a dedicated Stain block or simply an oil based undercoat. Then hang the paper. Hope this is helpful. Richard
