Yes, you could just tape it, but you will probably get better adhesion
if
you scrape off the paint down to the sheetrock paper on the adjoining
wall. Then, use your paper tape in the corners. (I hate those metal
inside corner beads.)

In a bedroom, I need to build a new interior partition 90 degrees off
an existing wall. The existing wall is painted (Benj. Moore eggshell
latex) and the new construction will need to be taped at the corner
where they join together. Can I just tape this corner like it was all
unfinished drywall, or will I need to prep the existing painted
surface to affect a good bond and sound tape joint?


Sheetrock Brand Durabond Setting Type Joint Compound will bond to paint.
It comes in a bag with
varying setting times..45,90,210...You mix it in a CLEAN joint compound
bucket with CLEAN water with a drill and paddle. Make sure
paddle,tools,bucket are cleaned BEFORE it sets.And yes the durabond on
the
paddle WILL set up HARD submerged in a bucket of water..LOL...Keep in
mind
that Durabond CAN NOT BE SANDED so don't get carried away and ONLY use it
to
embed the tape.

??? It can be sanded, but not very well.

Really..with what? A belt sander with 80 grit...LOL...your an idiot...Try
reading the bag for starters...

Finish with regular joint compound...

Only if you spray the primer on as if you use a roller you will loose the
taper on the mud and the joint will be visible.

BULL****....you have no idea what you are talking about....

I use Durabond to put
ALL the tape on in a house as well as the first TIGHT coat on the
cornerbead..I don't get callbacks for cracks...LOL...
