I find that artex ceilings can be right feckers for either sucking up the pva and still suck on the skim or it can be totally sealed and not suck at all.
You can normally figure it out when you roll on the first coat of pva whether it sucks or its sealed.

if the heating was on that could be your problem,hot air rises on yo your ceiling there could even be pipes running above the ceiling you are skimming. ive done it before myself the plaster was going off in 5 mins. turn the heating off fully let, the place cool down ,pva then skim again.

always turn heating off.

Keep your heating off , give walls or ceiling good coat of unibond 3 to 1 .
then Bonding coat walls or ceiling if artex you can then let the bonding coat tac up a bit then skim ontop of the bonding coat . JOB DONE ... IF your new to the job then you might be better of just putting the bonding coat on in one day and the skim the next day but if you do that then the bonding coat will of set so you would have to give the walls or ceiling a really good few of coats of pva as the first couple will just soak straight in to the bonding
