I currently have a large bathroom in my efficiency apartment that has your standard drop ceiling and the walls are old plaster and lathe covered by old warped panel board. I would like to tear down the panel board and put quarter inch drywall over the plaster and lathe to create a new service. However, the problem will be how to incorporate it into the drop ceiling. Is there an easy solution? Or must I take the drop ceiling down and then put it back up on top of the new surface? Suggestions appreciated. Thanks!
If it's just a bathroom, it really wouldn't take a lot of time to carefully remove the ceiling and put it back up when finished. It may seem like more work however it would make the boarding and mudding much easier. Better yet lose the drop ceiling altogether.
