I just finished installing drywall on the underside of a winding stairway for a client. Lots of pie-shaped pieces of drywall and funky angles, but it came out looking ok. My question is does anyone have any tricks to reach into deep, low angle corners to mud/tape where the the new drywall “ceiling” meets the existing wall. I thought about simply squeezing some caulk into the joints but I’d need at least a 12″ extension on the caulk gun tube to reach in there. Even if I could get mud in there, not sure how I could ever sand it smooth. Any ideas would be appreciated.

Buy a piece of 1/4" plexaglas and make your own, knife, tape a piece of sand paper on to sand.

If you thought what you need...you can come up with something.
Here is an idea......a 12" extension on the caulking gun tube?
good luck.
some times you can use a "long handle" brush to reach the spot.
You can even apply and smooth the materials with a wet brush.
good luck
The plexiglass Idea is good but it is hard to cut. In Myron Fergussons book he recommends cutting an old taping knife to fit into tight places. You could tape and extension onto the handle if necessary. As was said in an earlier post, you can tape sandpaper to the special knife to sand.
I'm not sure about the shapes, but can you use a wide knife (14") to get into the corners with one side of the knive? Also they sell really wide concrete steel floats that might work to smooth the compound. I use a 14" steel concrete float for all my outside corner beads as I get much better control and it can be used in conjunction with a smaller knife as a hawk.
Good luck
