Description Seal, Fix, and Bond – Even Underwater! Need to make repairs without draining your pond or tank? This powerful, fish-safe sealer does the job. Whether you’re fixing cracks, sealing holes, or bonding materials underwater, it’s non-toxic, solvent-free, and contains no isocyanates – making it completely safe for aquatic life. Stronger than your average sealant—up to four times tougher than standard silicone—it sticks to just about anything: plastic, wood, metal, PVC, glass, concrete, decking, boats, tanks, drains, coral, and more. (For concrete, be sure to use a PVA or concrete primer beforehand to stabilise loose surfaces.) It grabs fast and cures fully in 24 hours, depending on the colour and thickness of application.Gold Label Pond Aquarium Sealer
