Hi, I have been steaming paper off of the bedroom wall recently exposing perfectly dry plaster...no problem. I go back to it in a couple of days and discover a damp sticky band about 15 inches wide running from floor to ceiling. Oddly follows exactly the line of a wallpaper strip. Scraped away a section of the affected plaster and found it to be dry beneath. Three days on its still there. So can anyone tell me what it is and how to deal with it. Been told it could be an existing damp problem that has reacted once the strip of wall paper was removed. Sounds plausible. Thanks.
