Excellent sealant for Vivariums
I was upgrading two of my royal pythons and I needed a safe, good sealant to finish their vivariums. My very knowledgeable friend told me about this one. I got three tubes and I did 2 4ftx2ftx2ft vivariums comfortably with about half a tube left! I left it for 48hours, then fitted the light fittings and left another (working day) before setting them up and it was fully cured and safe. Keep it away from any animals (including humans) whilst curing; and if you can crack a window in the room it's curing in that would be a brilliant help. Good price, excellent product and a much better size than a previous brand I've used. I'll be helping my sister with her tortoise enclosure using this stuff too; I opted for clear as my finish is ash grey (black would have worked but was scared to make a mess!), however they have a range of colours. This will be my go to, animal-safe sealant from now on - highly recommend!

Brilliant
Great price and work so well Smell bad. But worth the time for the smell to go Used it for the background for a terrarium. It's held up the background covering so well and has been damp a lot.too. Id recommended it

Highly waterproof
Good stickability, but hard to remove from your fingers as it is highly waterproof. Seals well, no problems.

Works well as a sealant
Used to seal a vivarium. Would advise using in a well ventilated place and give at least 7 days to cure if using in a vivarium. Easy to use spreads well and seals well. It is sticky but dries with no issues. Does exactly what it is supposed to.
