Facade defect: mortar residues and smears - defect or not?

I'll put it this way, with a normal joint smoothing, you would have noticed edges everywhere on the bricks. And honestly, now it's too late anyway. If they cut out the joints again, you don't want that mess. And as for the dirt, it doesn't look that bad here on the phone. But as I said, acid washing doesn't really work properly on these rough stones anyway.

Correct, etching is also prohibited. It may not look "tragic" in the photo, but when you stand in front of the facade, it appears poorly finished.

I have edges in this form everywhere as well, but as already mentioned, the damage is done.

Here is another picture again. I can't imagine having to get by with this.

I can understand the frustration... even if a third party might think someone is making too much of it, as the client you naturally take it seriously and expect (rightly) that work is not or was not done carelessly. I find it difficult to judge whether the dirt is still within the tolerance range or already constitutes a defect, and I estimate that even experts would not all answer this question the same way (especially in such cases there is always a subjective component). But would there be anything against initially claiming it as a defect during acceptance and seeing if the general contractor is reasonable and willing to make a concession? By the way, I find the stone incredibly great, may I ask what kind it is?

The main contractor has already twice reluctantly tried to make improvements. I will, of course, declare it as a defect again during the building acceptance. If necessary, an expert must then intervene as a mediation body if no agreement is reached. Financial compensation would not be an optimal solution for me either, as I will be looking after it for the lifetime of the building owner.

Of course, the stone comes from Röben. Sand yellow multicolored!

Hm, then we should perhaps reconsider the Lehm-bunt from Röben after all :). But would a rework even be feasible (that is, without having to replace the entire facade)? I thought the only option left would be financial compensation, since the possibilities are exhausted...

According to the opinion of our GU and the companies Röben and Quickmix, it should be possible to brush it off, but so far this has not been successful, unfortunately. The next question would then be what amount of compensation we are talking about. This too can only be clarified by an expert. We will probably have to take this detour, as we do not assume that our construction company is willing to make further efforts.
