Underwater Sealant will seal & bond just about everything to everything:

  • PVC Pond Liner
  • EPDM Pond Liner
  • Vinyl
  • Rocks
  • Coral
  • Wooden decking
  • Concrete
  • Glass
  • Stone
  • Ceramic
  • Slate and the list goes on and on

It will even stick and seal underwater! Repairs may be made to wet gutters and roofs; leaks fixed in a chlorinated swimming pool without removing the water; or leaks fixed in a fish pond without having to remove the fish or plants. You can even use it to stick coral onto living rock.

Underwater Sealant is Non-Toxic

Underwater Sealant is non-toxic to fish & aquatic plants, inert, solvent & isocyanate free and has 4 times the bond strength of silicon.

How to Use

For best results clean all surfaces, to be free of Grease and algae. Place sealer directly onto the surface you wish to bond or seal. For bonding where there is movement (expansion & Contraction) of different substrates, leave a minimum 2mm thickness of bead between surfaces. Where there is livestock near the sealer, protect from ingestion while it is curing. Full cure within 24 hours, and initial tack takes 2-3 hours. Can be painted over up to 4 hours.  

To Join and Repair Pond Liner

For joining liner, use two beads 150mm apart and leave to cure for 36 hours at ambient temperature and for a patch, run a continuous bead around the edge of the patch and gently press into place. DO NOT PRESS FLAT. Use a 5mm bead for optimum cure and bond strength. Initial cure 24 hours, continuing to harden up to 7 days. For use on concrete, first use a suitable primer.
