Is the appearance of the new facade faulty or not?

He bought a house from the developer.

Hello,

the problem with ETICS is always that you see EVERY panel. You will have that no matter how good they are. Since only about a 5mm thick plaster layer is applied, you see every little unevenness. In a normally plastered house you have 1-2cm, which compensates much more. Walk through a new housing estate and look at the façades in raking light. You immediately see who used ETICS and who built solidly.

I think you won’t achieve much there, but trying never hurts...

Let us know what came out of it.

Regards
Tom

Not wanting to come across as an ETICS fan, but this is utter nonsense. The work here was done extremely poorly. Probably the substrate was already uneven and therefore not suitable for bonding the panels. The next step would be sanding the panels to remove unevenness. Ultimately, the plaster can be applied accordingly to smooth things out as well.
The panels also shouldn’t show through later if you used tongue-and-groove panels instead of butt-joined ones. But a developer will gladly save the extra €300 for that.
And that is a defect even a blind person can see. Imagine all the things the developer has probably covered up that you can’t just see...

This example has nothing to do with raking light anymore. Raking light is the enemy of every large, plastered surface. What we see here is visible even in normal daylight.

Hello,

I mean if someone builds with 24cm Ytong and ETICS, you can basically only say it doesn’t get any dumber ...

If ETICS then sand-lime brick but as mentioned, ETICS facades are ALWAYS recognizable. Maybe not as extreme as with the OP but you will always see it. Even if boards with tongue and groove are used, you can tell, that is the nature of the thing because the tongue and groove does not prevent the boards from tilting when glued. The usual plasterer only fills once. If you fill twice, you can get it done pretty well but you will still see it. I’m often in the new development area here and I can show you every house with ETICS even if they are nowhere near as extreme as the OP’s.

Alternatively 36cm Ytong WITHOUT ETICS, then he wouldn’t have that problem now (that’s how I built).

or simply KS+WDVS+cladding, then you can't see anything either

When I already read the questions of the OP here, it actually becomes clear what is going on. Not knowing how the general contractor or developer built but then wanting to plead for a hidden defect.

- Is a defect present, so that the function is impaired -> A clear NO!
- Did you accept it -> A clear Yes
- Does it look terrible -> A clear Yes

Something like that should really have been noticeable to you. Weren't you on the construction site every day?

Just ask the people here whose windows were installed 10 cm incorrectly or who now have some balcony steps that shouldn't be there, if they have received anything as compensation?

We live (still renting) in a 3.5-story solid house with ETICS. The entire side is plastered in such a way that I cannot recognize any unevenness, not even in the sun. Really amazing.

Ytong with ETICS is very cost-effective to produce and provides thin walls with high thermal insulation. In this respect, it is understandable, but for the builder, it may not be so great.
This wall construction is more frequently encountered here, for example from Town & Country or from developers.
