Quality of interior and exterior plaster

Oh sorry, I just noticed that you can also upload pictures directly ...

Attached are a few more pictures of my "main problems."

Yes, the question about the comparison, whether this passage about the GK panels can also be applied to brick walls, is justified. That came to my mind immediately as well.

We set up the grazing light to better illustrate the issue. In daylight, you don’t see the structure quite as strongly, but you still see it, and especially the horizontal joints of the individual brick rows are visible, which actually shouldn’t be the case ... I was just in another new building, where they are plastering right now, and there I see absolutely no structures. It’s really smooth and thick and especially straight, without waves and bubbles like with me

Where is the passage: "If nothing is agreed in the contract ... Q2 is considered agreed" from?
Is that stated officially somewhere?

For example:

"Q2 - This surface corresponds to the standard quality, e.g. according to section 3 ATV DIN 18350, or section 6.4.10 ÖNORM B 3346, recommendation SIA V 242/1, EN 13914-2 and meets the usual requirements for wall and ceiling surfaces."
