How do you fix wonky wall to ceiling corners pictured

[platforminc]

Hi All.

I will like to know how to fix wonky ceiling/wall corners like the one pictured below. My thinking is that if i caulk it to make it nice and straight then i can paint it, on the other hand I am thinking the walls are new stud walls and not sure if its a good idea to put caulk on it.

Thanks in advance.

Frog tape and then paint as you suggest... or buy coving!

That's what coving was invented for

Thanks. Do I need caulk or not ?

IME caulk will crack. Look for a paintable silicone. Or white if you have a white ceiling.

When I had a problem with wall/ceiling joints, I worked from above and injected expanding foam (preferably pink fire grade) along the edge to hold the wall and ceiling together, after hoovering out all dust. I don't know if that is generally considered good practice.
