Gold Label Pond & Aquarium Sealer – Black

Fix leaks and bond materials even underwater with Gold Label Pond & Aquarium Sealer in Black, a fish-safe sealant and adhesive that works without draining your pond or aquarium. There's no need to remove fish while it cures, whether you're repairing a leak or adding new features to your pond.

This versatile sealer seals underwater for an instant repair, and it's solvent-free and isocyanate-free, so it's safe to use around fish and aquatic life. It bonds almost all surfaces, including butyl rubber, vinyl, glass, ceramic, stone, concrete and wood, which makes it ideal for pond liner repairs, fixing rocks and features in place, and sealing around pipes and fittings. The black colour blends in with dark pond liners, rocks and aquarium backgrounds, so repairs stay discreet.

The sealer forms an initial tack in 2–3 hours and reaches a full cure in 24 hours. It can be painted over within 4 hours, so you can blend repairs into your pond or water feature for a seamless finish.

How to Use

1. Clean all surfaces so they're free of grease and algae.
2. Apply the sealer directly onto the surface you want to bond or seal.
3. Where materials may move (expand and contract), leave a bead at least 2mm thick between surfaces.
4. Allow 2–3 hours for initial tack and 24 hours for a full cure.

Please note: Where fish or other livestock are nearby, protect the sealer from being eaten while it cures. For major structural repairs on glass aquariums, such as failed seams, seek professional advice.
