I have recently had several rooms newly skimmed which I intend to paint. However have received conflicting advice as to whether should use "watered down" pva prior to painting as it will prevent the paint cracking. Advice please : "to pva or not to pva that is the question".
Do not use PVA prior to painting as this will create a seal between paint and plaster and will only make the paint peel.
The steps to follow would be to water down some white paint and use this as a base coat on the newly plastered walls.
Wait for this to dry and then you can go over the base coat with your desired colour/paint with 2-3 coats as you would normally.
If you do not feel competent to use watered down paint you can also go to B&Q where they sell off the shelf plaster paint which will be the base coat and no watering down will be required.
However this option may be a bit more expensive.
Hope all this helps

Hi Diane, i fully agree with Rhys, you should not apply P.V.A as it will create a barrier for the paint, you actually want the opposite to happen ie, the thinned base coat(white matt emulsion) to penetrate the new plaster, and then your desired colour and finish.

I use a mixture of pva/emulsion for miss coat before applying to further coats of a good quality vinyl matt emulsion,
alternatively Wickes do a very good new plaster paint.
Do not put silk paint directly on to new plaster

Hello... I would think that the skim has had pva added when applied so you would not have to use it.
The first coat of emulsion should watered down by about a third then two subsequent coats applied to achieve a super finish.
