Cork flats

[CrestedRick]

So I assume I’m not the only one that has experienced a bowed cork flat panel. Who do all of you get them to flatten out? I’m trying to attach a long piece of cork round to a panel and it won’t adhere due to the bow. The bow will also effect integrity when adhering it to the back of my conversion. It’s a 12x18 panel if that helps. I’ve seen some people steam their rounds and others soak them in boiling/hot water. What are some methods you guys have used? Soaking mine isn’t ideal due to its size.

I had a bowed one, and set it on a hard table with the bow side up, and put a very large, heavy book on it and left it for 3 days. It did flatten out enough to adhere it to the terrarium without a problem. I did the same when I put the adhesive on - kept the really heavy book on it for 24 hours until the adhesvie hardened.

I ended up just steaming it in a large pot and then screwing it to a piece of plywood for a yee days while it dried out.
