HPL facade panels show dents in the center and around the screw holes

Hello dear construction experts,

we have chosen large-format, anthracite-colored HPL panels for the facade cladding.
Part of it has already been installed, see photos.
The substructure is made of wood.
At first glance, it is clear that the facade does not have the smooth appearance we envisioned and that we also know from photos of comparable claddings.

The initial statement from the craftsman company was basically "it can't be done differently" – which we do not want to accept.
An acceptance has, of course, not yet taken place.

Does anyone know this issue?
How could these indentations have occurred?
How can the damage be repaired or prevented in the case of a reinstallation?

I look forward to hearing from you!

Best regards,
Janine

These are Tre*pa boards (may I mention this here)? What thickness do they have?

Hey, thanks for the question.

I also believe these are Tre*pa panels, but I cannot confirm it for sure.
I just measured them, they are about 0.55 cm thick, see photo.
I am also attaching a photo of part of the substructure.

I would ask the same question directly to the company Trespa with a few pictures attached. There you should get reliable information that also holds up against the craftsman. Nice is something else.....

It would be interesting to see how the plates looked upon delivery. I suspect that the screws were tightened incorrectly. The assembly instructions also clearly state that the screws should only be tightened by hand. You could try testing this with a few. The fact is that this is not acceptable as it is. Go to the company with corresponding example pictures and ask them to explain why others achieve a flat surface.

Thank you for your reply, Pagoni2020.

As I said, I am not sure if these are exactly the ones - our construction company could not say either, we are waiting for a response from the roofer about which manufacturer he ordered them from.
