Can I use emulsion as an undercoat on plaster?

'On fresh plaster, primer is normally an emulsion paint mixed with 10 per cent water – this soaks into new plaster, reducing its absorbency so new paint sticks to the wall.' An undercoat is used on a surface that's been painted or primed. Indoors it's fine to use a combined primer/undercoat.'
