Bloody worktops

I'm having a bit of a mare with worktop edgings.

Firstly they're not the standard 0.25mm laminate edgings that you just impact adhesive on and nearly trim and file.

The problem is they are a thick plastic, probably 2mm thick and they are concave slightly, probably from how they have been stored etc. But this means that when you try to stick them the pressure of the concave just lifts it off the worktop (down the center) , even leaving it overnight with weight on it.

The next issue is you cannot use standard Evo Stick impact adhesive because the solvent literally eats at the pattern and removes it from the edging ( the pattern is on the inside of the edging for some reason.

So issues are, I'm having difficulty cutting and trimming it Because it's too thick.

And I can't even stick it to the worktop the usual way

I'm going to get some unika tape and try that but I think I need to heat the edging up and remove the concave first.

Any suggestions?
Anyone seen this issue before?

 

Thank you both for your replies.
I too have just seen their website about the application with hot glue and the edge banding machine.
Wish I was alerted to this before it was purchased! Going to have to heat it up and try to remove the concave then I might stand half a chance.

Maybe to some sash clamps and a straight edge would help to secure it with mitre fast or tape?
