I went through the forum, and I did not find exactly what I was looking for. I am going to paint a friends living room. The house was built in the late 50's, plaster and button board. There are long cracks on the ceiling along the joints of the board. I see evidence that someone filled them in with just a little spackle and they came back. I want a permanent solution short of ripping down the ceiling. I was told to clean the cracks out a little and put in caulking (?). Then tape and mud the seams of the cracks, feathering it out. I am not the best taper so I was going to use the yellow self stick. Any ideas or critiques?
