Fresh plaster is extremely porous, and any moisture will be quickly absorbed into the wall. This is why you need to water down your first paint layer (known as a mist coat). Fresh plaster needs to be able to breath underneath the paint to allow any moisture to escape, so make sure to use a non-vinyl water-based paint.

Newly plastered walls/ceilings always need to be suitably sealed before painting begins (otherwise the paint will sit on the surface & come off very easily).
