l have a few dry patches on a internal wall that has wallpaper on it.. the wall is in the dining rooms chimney wall, it's not damp or wet .
l have pulled back some of the paper where the patches are near the skirting boards and the walls are dry but powdery, the walls are concrete/stone with plaster finish..
l've seen on here before someone mention a name for powdery/chalky walls could this be the problem with this wall and if so how can l cure it..
