We have lived in our home for 15 years, and I noticed some small ceiling cracks in the bedroom and bathroom. Hoping that there was nothing seriously wrong with the foundation or something, I decided to fix it myself.
My ceiling is not textured, so this made the process a little easier. I watched some videos online to see what was the best way to go about repairing these ceiling cracks.
It just took a few supplies from the hardware store. I mixed up some mud, applied to the cracks and let it dry. Once it was dry I lightly sanded it down and then painted over it.
While it would have been easy to just paint the area where the cracks were, I took this opportunity to put a fresh coat of paint on the entire ceiling. This made the room seem much brighter and the cracks have not returned.
