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

Hello dear building experts,
For the facade cladding, we have chosen large-format, anthracite-colored HPL panels.
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 expected and have seen in photos of similar claddings.
The initial response from the contractor was basically "it can’t be done any other way" – which we do not want to accept.
A handover has, of course, not yet taken place.
Does anyone know this issue?
How could these dents have occurred?
How can the damage be repaired or prevented in a reinstallation?
I look forward to your insights!
Best regards,
Janine

We had suspected something along these lines as well. Our builder is now trying to get in direct contact with the roofer and will get back to us. However, I expect confirmation of the statement "there is no other way because otherwise the panels will rattle." That’s what we heard most recently.

.... we are waiting for a response from the roofer regarding which manufacturer they ordered them from.I also think it’s as @danixf says. It’s possible that the substructure is insufficient. In any case, the screws must not be tightened too much.Miezekatze schrieb:
"there’s no other way"Yes, there is! Don’t let anyone convince you otherwise, this is shoddy work—you can clearly see it. Just imagine an entire wall of a school or office building installed like that... 😱 The manufacturer will also explain something about “rattling”... if that was the case, whole neighborhoods would be rattling... oh dear.
Miezekatze17 Feb 2021 20:15We are also quite shocked by the initial reaction... another manufacturer mentioned that when drilling, you need to be careful not to let the drill bit get too hot.
Our experience so far, with only one exception, is that you can no longer rely on any company—no matter how reputable they are presented to be.

Trespa is not the only manufacturer; even if it is a different one (Resopal or similar), they all provide precise installation instructions and various alternative fastening options (to prevent rattling). It is simply poorly executed workmanship, so the contractor needs to make corrections.

Baubaubau18 Feb 2021 11:39For us, the Trespa panels are screwed every 50 to 60 cm (20 to 24 inches) both horizontally and vertically, and they don’t warp at all. However, ours are 8 mm (0.3 inches) thick. From your pictures, it looks like the screws are much further apart; are they even fastened in the middle? Usually, there should be absolutely no denting right at the screw, as the panels are very hard.

This is simply a case of poor workmanship, so the contractor needs to fix it. We are indeed insisting on remedial work here. Last night, our builder suggested a “meeting” between him, the roofer, and us – but we see little point in that, since it’s clear to us that this is a case of substandard performance. We have now instructed the builder to sort this out with his subcontractor and ensure the necessary repairs are carried out.
