The white side of the plasterboard is the side that should be plastered this side is designed with tiny holes in the board which creates a key for the plaster another reason why boards should not be left for long periods of time on walls with no plaster on as they gather dust in these holes which again effects the adhesion of the skim coat. If you wet the brown(paper) side of the board for one you are weakening the board and if you plaster this side it is likely that when the paper is wet it will peel off the board and take the plaster with it and Ive seen it happen many times before it does clearly state on the paper side to plaster other side for this very reason

At one time the plasterboard was all brown faced to be plastered. The reason they changed to the ivory faced plasterboard to be skimmed, was because on the brown side the paper join can lift when plastered. It shouldn't do and you've no reason to use any PVA, because all plasterboard is a low suction background. Just make sure you scrim tape all the joins of the plasterboards before plastering.

Hi there, either side of the plasterboard is fine to plaster on and if you've put pva on aswell even better.

It does say on the brown side "PLASTER OTHER SIDE", I wouldnt PVA or wet it, you may find when you start to plaster it the brown paper divorces its self and you will end up with lumps...if you cant unscrew the board and turn it around you will just have to plaster it and hope for the best....

Its ok to skim either side but you may find the paper joint may come away ,and it takes a bit more trowel to get a good finish.
I have turned up to jobs over the years where the tacker boarded upside down instead of getting in removed ,scrim along the paper joint and skim ,

It is ok to skim either side of plaster board, ivory is slightly smoother than brown side, better for decorating on.
Google Lafarge or ring them direct, they will tell you the same.
