G4 clear


Price per Unit (piece): £15.50

This is an effective sealer for concrete ponds. G4 is a moisture cured, one component polyurethane product which forms a non-porous, tough, durable but flexible seal on concrete. This prevents lime leaching into your pond from the concrete and stops water leaking out. You just paint it straight onto the concrete, no primer needed.
  • Clear or Black colour sealant available
  • For a clear finish you need three coats - a total of 550g per square metre


G4 can also be used to coat flag stones, waterfalls, statues and other concrete products to make them safe for your pond.
