Product Information

If you have decided to make your pond from concrete then you will need to seal the top layer of render to stop the water getting in and the lime, which is harmful to fish, getting out.

The best way to do this is with G4 Sealer. You don't need a primer; just paint it straight onto the concrete. You can also use G4 to coat flagstones, waterfalls, statues and other concrete products to make them safe for your pond.

  • 4 colours available: Clear, Black, Green and Blue
  • For any coloured finish you need two coats of clear and two coats of coloured sealer. Thats 440g per square metre of clear and 400g per square metre of colour.

To work out how much you need, use our handy G4 calculator
