Bondaglass G4 Pond Sealer is ideal for waterproofing your pond. It is made from moisture cured polyurethane which forms a non-porous seal. It is ideal for waterproofing rendered brick ponds.

When using the green sealer, the first two coats must be G4 clear. This is because the G4 clear provides the maximum non-porous seal and adhesion. A further two coats of G4 green can now be added.

If you have a cracked pond, then the crack must be filled before then G4 can be used to waterproof it.

  • Polyurethane sealer forms a non porous seal

  • First use clear G4 then coloured G4
  • One can (1kg) is 1 litre
