The interior window trim has silicone caulk, and paint beads up or peels where it touches. Is there a dependable way to paint it, or should I remove and redo the caulk?
Can I paint over silicone caulk around my windows?

The dependable fix is usually to cut out the silicone carefully and replace it with a paintable caulk suitable for that joint. Clean off residue as the new caulk’s instructions recommend, and take care not to nick the trim or window. Check the window maker’s guidance first, since some joints need a particular sealant or should not be altered.

There are primers marketed for difficult surfaces, but paint over silicone can still fail, especially at the edges. If you try one, test a small hidden spot and let it cure before deciding. I wouldn’t count on primer as a lasting fix for a whole window perimeter.

If this was part of recent installation work, ask the installer to correct it before taking on the removal yourself. Replacing the bead is straightforward in principle, but a neat finish takes patience, and you don’t want to disturb a seal that serves a necessary purpose.
