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.
Garden ponds can often be over looked once the sun goes down, but with a few simple accessories your pond will transform your garden into an incredibly atmospheric space.
