Adding a partition wall in a finished room. New wall meets finished wall,
so
need to mud & tape the corner.

How do you do this? With latex paint on existing wall, mud won't stick
well.
Sanding latex isn't a clean solution, and anyway, using abrasives to get
down
to the sheet rock paper risks going through it.

Is this just a matter of patience and lots of sandpaper? Or is there a
better
solution?

Suggestions?

Thanks,

Just tape into it. The only adjustment that I make with paper joint tape is
to not force all of the compound from under the tape on first coat...the
latex paint makes it slide out more easily than with fresh gwb.
