Painting on bare plaster

I've had my walls skimmed and was wondering what the reason would be why the plasterer has then painted white emulsion directly on the plaster? I didn't ask him to but he said he always did it as it shows up any imperfections.
I thought you had to seal the plaster first? I'm now getting his paint peeling off, revealing bare plaster, as I'm trying to paint the room.

Alot of people will try this to save money on an appropriate new plaster paint , or pva size sealent solution !.
this "quick fix" usually always results in the paint peeling of because it reacts with the new unsealed plaster.
Not too worry tho with a good sand and prep, then a proper sealent coat before a re paint.... your walls should be fine .

Hope this helps

hi there
can I ask did he water the emulsion down or did he put it on straight from the tub?
in my experience its best to water down 50/50 to seal the plaster then allowing your top coats to be applied !
