Why do I have peeling paint in the living room of a stone house?

The 2 outside walls in my living room has paint peeling. I live in Canada in a stone house. There is a vapor barrier with insulation and there is no problems with the other walls. Any suggestions?Why do I have peeling paint in the living room of a stone house?
your getting moisture behind the paint. Where?? that's the kicker. Some way, some how moisture it getting to the wall. Being the outside wall naturally it's cooler and moisture condenses there and the paint is peeling so it's between the paint and the moisture barrier. So.... it may be a bad moisture barrier or it's coming from the top or the bottom. You've got no water stains or wet spots. Check to see if you have moisture in the window frame area. Check above , like in the attic to see if moisture is condensing up there and saturating down through the wall. And check for any places it could be coming up around the sills and the basement. It could also be that it wasn't prepped properly before being repainted or maybe a slightly incompatible paint put on over an existing paint and the extremes of winter temperatures is causing an expansion and contraction at different rates between the two different paints. What a pain, good luckWhy do I have peeling paint in the living room of a stone house?
The stone is emitting a product called efflorescence and will not allow any paint product to adhere. Step one, rinse area with a mild solution of muriatic acid and water. This will neutralize the bare spots on the wall and will NOT effect the surrounding painted surface. Let dry for a day or so, and then prime with an alkyd primer, topcoat with a latex paint. Cover all flooring materials with visqueen and a tarp to prevent damage to all other surroundings. good luck.
