We have a bedroom with lots of cracks in two of the corners. It's an internal corner (it's not on the inside of an external wall) and there's no reason I can see to think that there is any damp.
What's the best way to smooth the walls prior to painting? I guess it can be caulked but I don't know how to get a decent corner afterwards nor how to spread it well for the entire width of cracks. I'm also not sure if the cracked material needs to be flaked away first.
Any tips gratefully received, thanks in advance.
