Hello,
I'm about to install paneling on the ceiling. The paneling is a regular facade (small edge) with tongue and groove from Optimera, manufactured by NoviPro (norrlandsträ). They were delivered last week and have since been stacked evenly 95mm off the floor in my garage. Due to the heat, the garage maintains about 18-20 degrees with good ventilation.
Now, as I start nailing them up, a large number (so far) are shaped like a banana. That is, they lie flush at the outer ends but the tongue and groove barely meet in the middle. With force, it's possible to press some together, but if you hit them with a block and hammer, they spring back. So it feels like it's the planks that are warped. I'm shooting the nails into the tongue at an upward angle, so they don't obstruct.
What the heck do I do now? I'm afraid to open more packages to "test." It feels like a nightmare to return 500kg of paneling, if that's even possible. And how do you prove that something is "too warped"? Or do you just have to accept that they are like this? That this is the quality one should expect?
I thought this would be quick and easy compared to drywall. Any help and tips are greatly appreciated!
Kind regards
