In remodeling our 1977 built house, I moved a wall to make the small kitchen a bit larger and the large living room a bit smaller. I now have to "match" the two differant ceilings as well as fill in the holes where the old "above upper cabinet fill boxes" used to be (I'm not sure what these should be called).
The old kitchen ceiling was painted drywall with some sand added for texture. The old living room ceiling is a raised stucko type thick paint with deep valleys and high peaks. This makes this portion of the ceiling about 1/8" thicker than the kitchen portion. In between where the "above upper cabinet boxes" used to be will be new drywall.
What can I do to bring these 3 different surfaces together into a single ceiling that does not show the transition? Should I just bite the bullet and either put up new ceiling drywall over the old one (making sure it is anchored into the ceiling joists), tear down the ceiling and put up an entire new one (a messy proposition with blown insulation in the attic)? Is there another way I am not aware of like a bonding agent and skim coats of plaster? How about a mesh glued or stapled to the ceiling and then applying several coats of plaster onto/into the mesh (sounds crazy I know)?
