Posted By: tonyI would say either over working of the top coat or drying out too fast
Posted By: tonyDelamination caused by overworking with wooden float then,
It looks to me like the basecoat was not scratched to provide a key for the top coat.
Posted By: ComeOnPilgrimThe basecoat was well scratched all over, I saw it.
Posted By: ComeOnPilgrimOne suggestion is unslaked lime in the basecoat.

I think unslaked lime (i.e. quicklime) is unlikely in a packaged product but it's quite possible for powdered lime in bags to start carbonating and so become less useful. Whetehr that's a possible cause here, I've no idea.

I don't see any sign of it in that picture where the topcoat has come off?
Have you asked the lime supplier?
How was the topcoat compressed onto the basecoat?
Find a local expert and get them to take a look.
Posted By: ComeOnPilgrimThe render was sprayed on.
Posted By: renewablejohnAre you saying the topcoat was sprayed on but not leveled with a float. It seems very smooth for a spray coat. If it is just a spray coat then its a very poor mix.
