We live in "This Old House." Our house was built in 1863.
In our 1/2 bath upstairs, the previous owners put up drywall. Unfortunately, the drywall tape they put on is peeling. They only had to use it in the corners, and in every corner the tape is peeling. (It is also peeling in the corners of the slanted ceiling.)It looks like they put the tape on without any mud! The tape does not peel completely off, though. Is it okay to just put drywall mud over the top of the existing tape? Or, do we need to scrape off the old tape and start fresh? The paint on the walls is a shiny latex. Will the mud stick to the wall or do we need to put something on the walls first?
Thank you for all of the help!
