I have just put some plaster coving up (the paper covered stuff - like plasterboard) and now I need to paint it. Question is - can I paint directly on with a few coats of emulsion - or do I first need to seal it with a few watered down coats first?
I guess the same question applies to dry-lined walls where you will be paiting directly onto the plasterboard - do you have to use the same prepareation that you use for painting onto new plaster?
Thanks, Mark.
