Can you plaster over paint?

We've had the walls painted and then decided we want to skim them to get a perfectly smooth finish. Does the paint need to come off first? What are the steps that a plasterer would take here?

"No, you don't have to scrape the paint. PVA or SBR would do the trick and then skimming. Hope that helps"

"Do not listen to people just saying apply PVA Cheryl , either use Pink SBR Before hand that is a brilliant product or failing that apply a blue grit (your local builders merchants will stock)
Then leave for 24 hours before you skim and you won’t go wrong.
All the best ."
