Spot priming on plasterboard

[NewShoes]

Hey,

I've stripped wallpaper off in my hall and filled the dents, nicks etc in with easi-fill. I've sanded smooth but wondered what is the best way to seal or prime the patches of easi-fill? Some folk say just watered down emulsion (mist coat) and some say use a primer. Every primer I seem to look at says it's for wood or metal.. anyone know of a decent priced primer for use on plasterboard that has previously been painted?

Thanks,
-SN

I would go over the walls with a mist coat of Emulsion, once dry it will show up nibs and bumps which can be filled and touched in with the remainder of the mist coat, plus if you are thinking of repapering it will give a better surface to work on.
