Papering over old plaster

[MidsTW]

After removing the previous paper on our 1950's semi we had to repair the plaster underneath. Mainly minor hole, and some larger areas that we diy finish plastered

I have mist coated the areas which were new finish plaster. But question is..... Do I need to do any more prep work as well as sizing to the old plaster/small filled areas prior to papering?

A light rub down with a sanding sheet to remove any nibs, maybe a light second fill, I would have given all the walls a mist coat, this helps to show up any further imperfections before paper hanging,
Go ahead and size all walls

Cheers boss. I will give them a quick mist coat before I size. I have the time so might as well!
