Why do you have to wait for the first coat of mud that the tape is set in to dry? What happens if you topcoat paper tape as soon as its set in mud?
Who told you you have to wait? You don't.
The cheap stuff I use shrinks a little when it dries. 2nd coat over not fully dry = shrink shows thru on 2nd coat as all shrinks together vs just the tiny thin topcoat shrink.
Why even bother with 2 coats? Some folks just glop it on thick and sand off the excess.
Use 45 minute mud and it's no longer an issue and you'll get a better job.

Use timed taping compound in a bag-Durabond from USG for example (for first and second if you can handle it, and you can re-coat after it's set..........for the same reason as overcoating bucket mud.
Unless the bucket mud is set pretty good, you [JOBSITE WORD] up what you did, doing what you are doing................or, stand a good chance of [JOBSITE WORD] ing it up.

I am not concerned with getting it done quick in this case. I guess its just curiosity. Any pro taper I have seen always sets their tape one day, then comes back the next to start topcoating, even if its a really small project.
What do they bed the tape with?

Regular bucket mud.
Then that is your answer. It needs to set, shouldn't be rewetted/topped until that takes place. Bubbled tape is one possible result if coated too soon.
I asked this same question to the fine folks at USG - Tech Help to be precise - years ago. I was told that if a new coat of readymix compound is applied to a coat which is not dry, it will not bond properly. On the microscopic level, it actually "floats" on the previous coat.
A dry prior coat actually sucks the moisture from the newer coat and pulls the new compound tighter to it thereby creating the better bond. Their actual words were "The compound needs to be dry so it can suck in the subsequent coat and create proper bonding."
Hope this helps.
