    Default Mysterious leaching of painted wall

    Hi

    When we first moved into our house, one of the bedroom walls (adjacent to an attic)started to "leach" in the winter as the temperature drops.

    The "leach" visually looks like long drips running from the top of the wall to the bottom. At the bottom of the drip sometimes an "oily" like substance can be felt. This has been ongoing every winter for the past 12 years. The wallboard itself is structurally sound as is the paint surface.

    The rest of the walls in the room are fine. And the wall that is leaching is colder than the others.

    Any thoughts on what this may be? Thanks

    Could be a number of things, though from your description it would seem humidity and temperature have a roll in the appearance of the mystery goo.

    Have you ever noticed a similar issue in your bathroom? Here's what's happening, warm moist air is condensing on the walls. This is "washing" the dust and dirt from the air as well as the walls, and as the moisture collects enough to run, the goo forms these telltale tracks.

    A similar thing could be happening in this room. Odds are it's a cold room that's not used much (or well ventilate ). When you open the door, a blast of warm are from the rest of the house enters and forms the condensation. Over time, it builds up enough to drip and run. Try leaving the door to this room open so that it gets more heat as well as a little ventilation.

    room is a bedroom - its heated of course and relatively warm and door almost always open.

    we have baseboard heat - not forced hot air. no ventilation near the area behind wall.

    once in a while i see it in bathroom, but not that often - though we used paint in the bathroom that is supposedly bathroom paint..

    Your description sounds fairly complete, so my $$$ is on a lack of a vapor barrier between the attic and the bedroom and the lack of sufficient insulation. Any possibility that it might be a roof problem. Having complete access from the attic side would be a big help. Jim
