I have just had my house replastered and now plan to paint the freshly plastered walls. I have a couple of questions that I would appreciate advice on.
Firstly, I have received conflicting advice as to what to use as a primer. My plasterer recommended using watered down PVA but since then I have been looking about the internet and the general consensus seems to be using a watered down non-vinyl matt with a paint:water ratio of about 3:1. Which is correct?
Secondly, I know that the plaster is supposed to be bone dry before priming but assuming I am using watered down paint as a primer I don't understand the point of waiting for the plaster to dry to then just put the water back into the plaster with the primer. I was under the impression that the paint prevents the water from escaping to the atmosphere causing all sorts of problems and if the paint does allow the water to dry then what is the point in putting the water in the paint in the first place?
I hope these questions don't make me sound too stupid but obviously I just want to get the job done properly without any problems. Thanks in advance.
