Hello, I am finishing my bathroom however I wallpapered and painted the ceiling before I sealed the gap between ceiling and wall.

 

Should I use decorators caulk for this, or silicone? And if silicon, should it include some mould resistant properties?

Sanitary silicone. Ideally colour matched to your grout.

Thanks. Elsewhere I have been suggested decorators caulk, which can be painted afterwards.

With the colour matched silicone, you don't need to paint. Painting sucks.
