Hi everyone! I am making a bio active setup in a 30x30x45cm vertical terrarium and I want to make a backdrop with cork bark and some driftwood to make it look nicer and have some good climbing surface.

I’ve read a lot of different opinions and watched different build videos but I couldn’t get to a consensus on how to proceed with the build.

Some say put silicon as a first layer and then foam on top, some say foam first and then cover it with silicone…

In the pictures are the foam and silicone I got. Please help with an advice and let me know if the you have any experience with this foam(Pond Boss – pond and stone sealant)

Thanks!
