new drywall joins to existing painted wall

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.)

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...

I have to repair a wall and wonder if I should cut out the drywall all the way to the ceiling or just below it then slip new peice in and tape up to it

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

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.
I use Durabond to put
