Are you sure about this? *All books I've read on the topic as well as some online sources (say,http://www.diydoctor.org.uk/projects...newplaster.htm, for example) say only to do this with special paint such as Wickes New Plaster Emulsion or Dulux Supermatt.

Well, my standard method of painting bare surfaces is to wet it, give
it 5 mins to soak in, then paint without diluting. Its always worked
