Today’s post will be on one of the most common background options. Great stuff. I will also add gorilla glue backgrounds as well seeing they are both pretty similar and both start with G.
Great Stuff & Gorilla Glue
Great Stuff
Let start with the great stuff. Great stuff is the expanding foam that is typically used for insulating gaps around the house, however it has been used for many years as a background for terrariums. This material is great because you spray it on and then come back later to expanded foam and you can carve it into almost any shape imaginable. Once you are done carving you have endless possibilities for covering. People typically use silicone, gorilla glue or titebond 3 but you can use whatever you would like.
Here is a quick guide on one way to make a expanding foam background from Sambridge15 on the reptileforums.co.uk.
Step 1- Place wood & pieces where you would like them.

Step 2- Put on gloves & Foam in a little bit of expanding foam

Step 3- Apply Silicone & apply lots of substrate material

Step 4- Touch up any areas that did not fully cover on the first pass through.

Step 5- Admire work!

Gorilla Glue
As mentioned earlier gorilla glue can be used to cover great stuff, however it can also be used as a background material itself. Unlike great stuff it does not expand as much so what you have before it dries will be more similar to the finished cure. Here is a guide on one way to make a background using gorilla glue from Wolfenrook on the reptileforums.co.uk.
Step 1-pour layer of glue on glass.
Step 2- Spray glue with water to get it to foam up

Step 3- Give the glue 5-10 minutes to foam up
Step 4- Push in your substrates of choice

Step 5- Keep an eye on the viv and push more substrate in to create desired terrain
Step 6- Give the tank 2-3 hours to set & repeat on any other surfaces you would like to cover.

Here are 2 photos of tanks made by Dendrobati:

Great idea!
Evalina, This and that…
Thanks! I wanted something hard enough to challenge me, but not too hard that I would get discouraged. I think I ended up with something right in between. So far so good!
I just love all your ideas! They’re very creative! Next! H is for … 🙂
Thanks! I cannot take all the credit, as most of these ideas have been around for many years prior to me getting any frogs. H is for Hygrolon! It just posted a little while ago! Sorry for the delayed response but I was in Iowa for work!
I’ve seen Great Stuff used for terrariums before, but not gorilla glue/substrate. Mostly because I’ve always kept bearded dragons and they’re no good with loose particle substrate. Lovely set ups!

Great stuff covered in silicone is definitely more common. I haven’t tried the gorilla glue method myself yet. But it does sound like it would have its perks! I have heard it is a lot less messy than silicone.
It is crazy to hear how many people keep bearded dragons! Throughout this A to Z Challenge a lot of people have mentioned that they keep them!
They’re a really popular pet now because they’re so cool to look at and so docile. I had to give mine up when I moved to Japan though/ Saddest day of my life. 😦
😦 yeah it is really hard to give up a loved pet! I know I would definitely feel the same way!
