Being a DIY novice, I've recently had my wall replastered. I was told that I could paint it after a few days. Anyway, I waited about 3 weeks before I painted, but someone has just told me that I should have sealed it first. I don't know what to do now. Whether to just leave it and hope, or to strip it off and start again. Any help greatfully received!! :oops:
the first coat of emulsion on new plaster is usually thinned at a ratio of 2 parts emulsion to 1 part water and is known as a mist coat and this is sufficent to seal the plaster prior to painting, however if youve already painted the plaster you shouldnt need to do anything else to it unless you have any problems, cracking or flaking paint etc.
Doesn't sound like you will have a problem to me. All that happens is that you are using yuor expensive paint to cover the plastered wall.... for next time, as topdec suggests, a thinned coat of paint first or alternatively you can use PVC glue watared down ratio 1 part glue to 5 parts cold water. Mix it up and then just paint all your walls using a brush or a roller. You can do a couple of coats if you want to be thorough. Let it dry over night and then start your painting.
Your coat of paint will do exactly the same as this, but glue and water is cheaper! (method recommended to me by a plasterer).

i would strongly disagree - emulsion paint does not take very well to PVA'd surfaces. if PVA is used then add it directly to the diluted paint in very small quantities to help adhesion. painting over dry PVA often fails.

Fair comment... but I have used this method several times and it works fine. Each to their own i guess!
