Product Description

Perfect for sealing block built / rendered ponds

Concrete based ponds need the final render sealing to stop the water getting in and lime leaking out. G4 has been long established as the market leader for this task. You need 3 coats of clear G4 when you apply it to a pond. This is a total of 550g per square metre.


  • The amount of G4 you will need depends on the internal dimensions of your pond. For example lets say the pond is 3m x 2m and 1m deep.
  • 1) Work out the area of the bottom (in our example 3x2m = 6sqm).
  • 2) Find the area of one of the sides. then multiply by 2 to cover both sides (in example sides 1 = 2x1 = 2sqm x 2 = 4sqm)
  • 3) Find the area of the other pair of sides: (in example sides 2 = 3x1 = 3sqm x 2 = 6sqm).
  • 4) Add up sides and floor (6sqm + 4sqm + 6sqm = 16sqm)
  • 5) Multiply total by 550gsm = 16 x 0.55kg = 8.8kg
  • Leave for 45-60 minutes after first coat
  • Do not leave for more than 4 hours between coats
