Hey all, I was just wondering where the best place to purchase some vivarium and frog safe black silicone is. I’m aiming to attach eco earth to a DIY background made from expanding foam.

The total surface area to be covered by the black silicone is approx:

30cm x 45cm for one side wall and,
30cm x 45cm for the back wall

Suggestions would be greatly appreciated! It's causing me a headache at the moment :-(

Thanks a lot in advance!

p.s. I live in the UK, so a UK store would be fantastic, or an online order that can deliver to the UK.
