I am completely new to anything like this. We are renovating our living room and had a plasterer come in and skim over 3 rough/chipped walls. They look good and smooth now, but when I asked his advice re prepping and painting them, he said that after they have dried, sand them down then use use pva mixed with water on all the walls, then after that has dried put on a couple of mist coats then emulsion.
However...
Everywhere online seems to say dont pva straight on to new plaster when its dry as it will seal it and not let the paint absorb into the plaster.
What is the correct way? I don't want cracked newly skimmed walls!
ALSO....
One of the walls was not skimmed as it was good and is just smooth old plaster - do I treat this differently? It hasn't ever been painted.
