Would this be suitable for joining two rubber pond liners together?

Dear JSG, thank you for your question. I am afraid this is not suitable for joining pond liners; please do not hesitate to contact us for further information. Kind regards JC Plastics Ltd.

Is this 100% silicone ?

It says it is i would get the clear one 100% silicone hope that helps

Dose the silicone come with a lid to prevent drying of excess?

Sadly no. Once you’ve cut a hole for it to come out, that’s it, but I just put a plastic glove over with an elastic band to hold it in place.

Has anyone used this to glue aquarium ornaments together? Have tried sealent which didnt work.

This stuff is excellent and will definitely do the job
