Never had any problems with mud taking to latex paint. In fact if I have raw
gypsum edges that need mud to stick to them, I always paint or prime with
latex to make the mud stick. Also after priming with latex one often finds
divots or rough spots, adding mud to smooth these out is standard practice.

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,

ask a question here if I hadn't done that already.
