I've got a damp cellar in my c.200 year old stone-built house - not a particular problem as I have no plans to use it for anything other than storing junk. However, one section of the ground floor wall seems to have rising damp. Most of the ground floor walls have no covering - the original stone is exposed and painted - however the particular section that is damp is in a downstairs WC which has been tiled. The reason I discovered the damp (apart from the musty smell) was that the grout around the tiles had a white (salty?) deposit on it after the winter and it appeared that the (thick, powdery) plaster behind the tiles was expanding causing a couple of the tiles to crack.
Having read this site a bit I am guessing that the problem may have arisen because the tiling will not let the wall breathe, so I'm tempted just to remove all the tiles and the plaster and expose the stone, like in the rest of the ground floor - might this solve the problem?
If so, is there a particular paint that I should use to paint the exposed stone?
Thanks a lot in advance
