Problem with wall between living room and bathroom.

Anne Staff asked 4 years ago

Had a friend 2 yrs. ago paint the inside wall of historic home, mine, with satin paint instead of flat paint to make “area more inviting and warm” (his quote). The reason why I used flat paint in the past was because this area was known to peel very often, flat roof and air ducts are floor level not roof and we could easily scrape down and repaint.

Well, he talked me into using different type of paint in which was a lot more money and at the time it did look good. HOWEVER, not for long. The peeling and bubbling came back quicker and worse than ever. He was not a contractor so I am out of luck there. Took steps to repair, plumbing in bathroom, which he “took care of” and repainted wall between bath and living room. Had a roofer come out, no leak. Had AC man come out, all air ducts are sealed.

I do not know what to do. Should I strip off old paint and go back to flat paint. PS – do not have friends do home repair – back fired.

Definitely a moisture problem with your wall. If I understand this correctly, the wall is between your bathroom and living room. This is an interior wall.

It is weird to have this problem on an interior wall. You have already check the two major areas, plumbing and roof. Do you have a crawl space under your house? If so, this is a good area to look at. Hopefully the problem will be more evident from a different angle.

I do have one suggestion;

Go ahead and scrape or strip off as much of the paint as possible. Let the wall breath for a couple of days. Then apply a piece of 6 mil plastic, 2ftx2ft, with duck tape to the wall. Tape the edges solid. Let the plastic sit on the wall for 2 days then peel it off and see if any water has condensed on the wall or plastic.

If so, then there is water in the wall. The source of the moisture should be found before repainting. If this proves too difficult, go ahead and repaint with a flat paint. Keep trying to find the source of the water. Left unfixed this could cause rot and mold damage.
