## Questions & Answers

**Q: Will it be ok for bonding my pond liner to a plastic bottom drain in my koi pool im building**
A: I want to reseal my fish tank just wondering do I seal it from the inside or the outside. Thank you

**Q: can this rebond a large silicone button to a circuit board/electronics below? (The original manufacturer adhesive became soft and peeled away.)**
A: noooh! you need a hot glue gun for such a job or superglue /gorilla glue .This stuff is like what you get around your bath and sinks .It bonds but not enough to be used to hold a button stable .Ht h

**Q: i want to "glue" large pebbles to pond liner making a stream i need to stop the pebbles rolling into the middle would this be suitable .. fish free ar**
A: I used it as aquarium silcone, and it was perfect for that. The pebbles should have at least one flat side in my opinion to stick nicely, otherwise you have to use a lot of stuff to glue them to the liner. Once it dried it is strong enough though...

**Q: How big is the tube... I have 120ltre tank to reseal will 1 be enough**
A: The tube is the same size as any sealant tube you buy from any DIY shop .. the ones that fit in the regular size guns .
My tank is 160ltr and it was big enough to resell that and also convert it into a turtle tank with different layers .
As long as you don’t go daft and use absolutely loads to resell your tank I would say 1 would be enough .. but just get two .. I have a spare one in my shed all the time .. it’s great to have the peace of mind knowing it’s there for an emergency.
