This Gold Label pond repair sealer will allow you to patch or repair cracks, holes, damage to your pond or aquarium, or to join liners together, and is completely fish safe!

The clever non-toxic and solvent-free solution can be used safely above water or underwater, even while fish are still in the pond or tank, whether it be saltwater or freshwater. Meaning that you don't need to disturb your fish by emptying them out and draining your pool first. It can even be used on pools that contain chlorinated water to patch up any pesky cracks or holes.

With the strength of four times that of a normal silicone sealer, it will bond to almost any surface including stone, concrete (concrete primer required), wood, butyl rubber, glass, and composite plastics. It starts to work instantly and will be fully cured in around 24-hours. All you'll need for quick and easy application is a cartridge gun (not supplied).
