i have just had all 3 bedrooms in my new house re-skimmed on all the walls and ceilings etc as just rewired so want just painted walls as opposed to re-papering,the plaster work is still drying out and i am preparing my materials/tools list for the job of painting it all with emulsion...my question is do i apply a coat of pva to the walls 1st for the plaster to absorb or do i mix some pva in with the emulsion in the bucket and then apply the 1st coat...cheers
