wait until all the dark pink/grey plaster has turned pale then your ready to decorate. decorators used to "size" the walls prior to wallpapering using a solution of wallpaper paste as a primer. i guess you can seal the plaster with either a solution of diluted pva or emulsion usually 50% water 50% emulsion. best to ask the guys at decorating forum for confirmation though!

Emulsion gives a better surface IMHO. Mist coat first diluted with water, then at least one finish coat. This levels up any colour differences, especially if there are filler patches, and enables the eye to spot any surface defects so you can fix it before papering. It stops the absorbency of the plaster grabbing your pasted paper. It doesn't build up or come off like size, and is easy to wash clean next time. And if you don't get round to papering for a while it looks decent.
