I have a very small half bath and the existing drywall is messed up. Specifically, the previous owner thought that it was a good idea to apply several coats of paint over old wallpaper paste. It looks like alligator skin which is not the look I'm going for. Suffice it to say that I cannot fix this problem. I've never hung drywall, but i'm very familiar with the patching process. A guy at Home Depot recommended that I apply 1/4 drywall over the existing drywall and essentially start from scratch. Here's the problem-the ceiling is textured. I don't know how to tie the new 1/4 walls into the existing ceiling- i can't just tape it. It would be difficult for me to replace the ceiling. Any thoughts? Im actually thinking about having a professional do it. I dont enjoy home improvement like I used to.
