Product Information

Bondaglass G4 Pond Paint is ideal for waterproofing your pond. It is a moisture cured polyurethane which forms a non-porous seal. It is perfect for waterproofing ponds made 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 can now be added.

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

Key Features:

  • Polyurethane paint forms a non porous seal
  • Suitable for ponds made from rendered brick
  • Hardens in the air
  • First use clear G4 then coloured G4
  • One can (1kg) is 1 litre


1st and 2nd coats = clear 410g / metre sq.(for 2 coats)

3rd and 4th coats = black 400g / metre sq. (for 2 coats)

    Have used G4 plenty of times in the past and is usually a great product. This sample was rubbish. Almost too thick to get out of the tin. Impossible to paint on properly. One bad coat applied to a veg filter and the remaining half a tin left to be thrown away at some later date.
