Product Information

Bondaglass G4 Pond Paint is ideal for waterproofing your pond. It is made from moisture cured polyurethane which forms a non-porous seal. It is ideal for waterproofing ponds crafted from rendered brick. G4 Pond Paint uses the moisture in the air and substrate to cure and harden.

When using the black paint, 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 black/green can now be added. If you are looking for a product that sets clear we recommend buying Bondaglass Seal Clear, this is ideal to use when painting stone water features for that clear discreat look!

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

  • First use clear G4 then coloured G4

    Only reason for 4 rather than 5 stars is that key safety information was buried in the small print.
