Have to agree with Dextrous as newly plastered walls only need a mist coat and away you go. The lining paper gives the surface an even absorbancy rate if its going over different surfaces like plaster, filler, old plaster etc.
The newly plastered wall will already have one even absorbancy rate.
If the wall is to be papered, then certain papers require that the wall be lined first. If its to be painted then there is no need for the lining paper.
