Hi There, this could be a sign of moisture under the Emulsion causing the paint to flake and feel chalky, alternatively it could be due to poor original mist coating of the plaster below. Photos would help.

Hello this is efflorescence which is caused by damp penetrating through the brickwork and plaster. The cause of the damp needs to be stopped. Once dry scrape off chalky residue and apply 2 coats of Zinsser watertite then fill and paint as normal

It’s probably poor preparation use something like Zinnser to cover it up and seal it

If not due to damp, could be something spilt or sprayed on it causing a reaction?
