Gold Label Underwater Sealer does exactly what its name promises: it provides a rock-solid, waterproof bond in fully submerged conditions. A truly remarkable essential for both pond and aquarium owners, this sealer lets you instantly patch a cut in your pond liner or seal a heavy-duty fixture without the hassle of draining your water. Whether you need to bond stainless steel to plastic or wood to stone, the Gold Label Underwater Sealer ensures a permanent, leakproof bond for complete peace of mind.

How to Apply Gold Label Underwater Sealer

  • Preparation: For the absolute best results, ensure all surfaces are thoroughly cleaned and free of heavy grease, dirt, and algae before application.
  • Application: Squeeze the sealant directly onto the surface you wish to bond. If you are joining materials that are prone to movement (expansion and contraction), ensure you leave a minimum 2mm thick bead between the surfaces to allow for flexibility.
  • Curing Times: The sealer will develop an initial tack in 2-3 hours, can be painted over after just 4 hours, and will achieve a full, heavy-duty cure in approximately 24 hours. (Please note: It is not suitable for use in temperatures below 10°C, or on Polyex, HDPE, or LDPE plastics).
