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?

Perhaps use a J bead at the end of the new partition and allow a
clearly defined joint to be visible.

If you choose to use a conventional right angle joint, it only takes a
couple of minutes to scarf off the area where the taping takes place.
Most people would just use an angle grinder with whatever abrasive
disc is handy. Keep your shop vac handy and the small amount of dust
won't be a problem. HTH

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.)

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. Finish with regular joint compound...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...

the way to the ceiling or just below it then slip new peice in and
tape up to it

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

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.

Go all the way to the ceiling...Corners are MUCH easier to tape than
joints....
