I was planning to remove the old ugly cove moulding on my stair stringers. 30 years of lazy paints jobs have left it in a very bad state.
My initial plan was to just sand the stringer and wall, get them all cleaned and patched up and looking good, then caulk the right angle where they meet.
However, when I started prying off the moulding I discovered the drywall doesn't actually meet the stringer. It's about half an inch short.
Is there any durable, secure way to fill this void and achieve the clean finished angle I was hoping for, or am I going to have to resort to covering it back up with quarter round?
