I am getting frustrated. I'm using paper tape and not the fiberglass mesh. I saw a YouTube demo to get this tape and float thing down. The guy put joint compound first and then wet the tape before applying it. The problem I'm having is, now that it's dry, there a places where the tape has bubbled up. I'm guessing because of the wetting. 1. Is there anything else I could be doing wrong to cause bubbling? 2. Do I need to rip out the tape, sand and reapply or can I peel the tape shove compound under it and smooth? 3. Could anyone provide better instructions or a link for taping the corners?
