Painting newly skimmed walls

Posted by Diane Rimmer, on
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".

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.

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 Mick Emery Emery Painters Decorators

50/50 emulsion definitely, and don't leave it too long. Dry plaster will start absorbing moisture if it's left un sealed.

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. Thank you B J Lenehan

hi Diane, Don,t PVA walls as this will seal the new plaster use a 50/50 mix of emulsion and water this will soak into the new plaster and then finish with normal emulsion. Mike
