Do you need to wash new plaster before painting?

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.
