We have a 200 yr old house in the Tarn. All rooms had lovely vinyl wallpaper on them! Underneath this in one room is a caramel coloured paint (patchy) under which is a pale blue powdery 'distemper'. Does any one have any experience on the best way to stabilise this surface prior to re-wallpapering. Can it be stabilised with weak wallpaper paste solution or should it be removed, if so how? Many thanks Tarn Addict
