I agree there is nothing wrong with just
taping it and widening the mud a bit.
However, I have, on occasion, done the
following: Using a utility knive (box
cutter type) I cut the surface paper at
an angle away from the joint on both
piece of drywall. Then, the paper can
be pealed off. This give a depression
for the new tape and mud. Not as messy
as grinding!
