Varnishing new plaster. Can anyone help??

[thedavidnicholson]

I have had a room newly plastered with plasterboard and a plaster skim.
I love the colour of the dried plaster and want to varnish one of the walls with a clear transparent sealer.
One possibility is to use PVA with the first coat being very diluted(50-50 water?) then gradually building up with more coats of pva. I assume that because pva is transluscent when dry that the more coats will give a greater depth to the finish. However I have read on some forums that pva shouldn't be used on new plaster as it is not breathable etc.
Another alternative would be to use a water based varnish and dilute that although this could end up costing a bit more!
Lastluy if I don't like the effect of the varnish/pva will I be able to repaint the wall with flat white emulsion.
Any help greatly appreciated.

Personally...Dont. it will change colour anyway to quite a darker shade of pink, may seal it too much so the wall cant breathe.......and basically look abit naff.

Your best bet would be to have an emulsion colour-matched to the new plaster and paint that on for a uniform finish.
Most decorator trade outlets do this if you can give them a sample of the colour.
