Ceiling Slabs too dry for plaster

Antofair

Hi
Building a new house and started to plaster inside and have the ceiling slabs done and all the ext walls done with insultaed slabboard.
The scratch coat is done on the inside now and when the plastered when to skimcoat the ceiling slabs he was saying that the skimcoat was drying too fast and becoming hard being unworkable .
The ceiling slabs were installed about a year ago I the house.
The skimcoat is brand new in the bags well with indate, the water is fresh and he have nearly 20 years exp plastered.
Have the slabs become too dry in the house and are absorbed all the water from the skimcoat
What can I do to fix this issue , like apply a fine mist of water and let it dry in to raise the water content of the slab first as the only alternative is to replace all the ceiling slabs

Any suggestions or ideas would be great

Thanks

You could thistle bond the slabs

Looked up thistle bond , it seems it might do the trick
Will talk to plastered tomorrow to discuss

I'm curious, didn't the plasterer advise on what to do? Surely with almost 20 year's experience he must have some idea of a suitable solution.

There can be a massive difference between someone who has 20yrs exp at a trade , and someone who has 20yrs worth of knowledge at a trade

Well he did suggest thistle bond as well , but said it was only design for small areas , if he had his way he replaced all the slabs
90% of the house is now thistle bond and being plastered with no issues
