Question: Axolotl friendly sealant? DIY Background

[Spartacus]

Hi guys

For ages now, I've been working on a 3D background for my axies. It's the typical foam and concrete combo. I want something safe to seal all the concrete/concrete oxides in?

Heaps of people say either epoxy resin, or polyurethane coatings, but others say no to these. I'm wondering if any axie keepers have experience with this? Cause axies are extra sensitive to chemicals, and I don't want to risk something that is ok with fish, but might not be for axies.

Advice anyone?
I don't need product names (i.e krylon fusion paint), just what type of thing it is (i.e epoxy resin), because in NZ, chances are we don't have it by that name, and I just really need to find something! It's almost done

Thanks

I'm using pond sealant. You may have it in NZ, just make sure on the back it says that it's safe to use. The brand I'm using is pH neutral, non toxic to aquatic life and plants and can be used with areas that collect and store drinking water.

Thanks, I found some stuff like that, paid $100 for it, only to open it and realise it's black! I haven't managed to find a clear kind yet its a shame cause the black works really well, but I need a clear one for this project

Wow that's so expensive. The brand I used only cost I think $26 and comes in clear. It's called cromellins waterproof sealer, bought it from bunnings. Maybe if there is a bunnings in NZ or perhaps you can get it delivered?

After a lot of searching round, I found some "pond paint", which is just a sealer that is aquarium safe. Still a wopping $80 though. I think some chemical in all these products must be banned here, because I can barely find anything that isn't sold in large quantities for industry work. Bunnings Australia had the cromellins but nowhere in NZ *sigh* og well, at least I've finally found some clear stuff thanks!
