Moisture Issues: Cracks in Ceiling Paint


A crack formed on the ceiling of the bathroom.  The crack got gradually bigger through a 1-year period.  There is an exhaust fan in the bathroom, with a window that is usually opened when showering.  This bathroom had been remodeled in the past, and was plaster originally.  not all the plaster was removed.


1) During remodel, texture skim coat was applied directly to the old plaster.

2) The brand of paint used to paint the bathroom during remodel was discontinued and could have been bad and assisted in the cracking of paint and texture.

3)  Exhaust fan was dirty and was not clearing the moisture appropriately


1)  Remove paint and texture at source of crack, scraping until the paint does not chip away easily

2)  Skim coat scraped area, making the scraped area blend in with rest of the surface

3)  Texture and paint to match

Hints and tips:

1)  Clean your bathroom exhaust fan monthly with “can-o-air”, a small wire brush makes it easier to scrub in the fan blades.

2)  If your exhaust fan sounds louder that usual, or sounds like a baseball card in the spokes of a bike, it is time to clean it

3)  When doing a skim coat, make sure you work in the mud into the edges where you stopped scraping away to ensure adherence to the old mud/plaster.

4) Home depot did a great match of this paint, especially because the original paint was discontinued.  Remember, when going into match paint; take the old can, or the largest paint chip you can get.  Typically, they say quarter size is big enough, but I have gotten some bad matches taking in this size.

5)  If you have a window in bathroom and can open during showers, this will assist in clearing moisture out more quickly.
