ᐅ Fine skim coats can reveal cracks after plastering.

Hello,

I wanted to ask if anyone has an idea.

I applied fine filler on gypsum plaster. Now small cracks are forming. What could be the reason?

Did the material not cure properly, or should I have applied a primer twice?

I primed the wall beforehand.

Regards

Dirk

Did it dry too quickly, or was there a draft or something?
