Hi Diane, 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 RJB Construction Quality, Honest & Reliable Building work Specialist in Plastering and Decorating.
