Tape the joints first with scrim tape-

Then skim the ceiling with finishing plaster-

You have to be fast with ceilings as they dry out fast and so two coats is preferred.

Answer 2

What goes on the plasterboard now is cement similiar to stucco cement...which has to dry. Plaster is just a thin white coating that goes ontop of the cement.
I know this because this is what I have been taking out of houses that are being renovated, using a hammer to break all this crap down and replace with drywall(gyproc) which is soooo much easier, faster, lighter and more resistant to cracking.

Answer 3

You would be better off with an overcoat and will provide good insulation.
