This is an effective sealer for concrete ponds. G4 is a moisture cured, one component polyureethane 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.

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

For a black finish you need two coats of clear and two coats of black. Thats 440g per square metre of clear and 400g per square metre of colour.

G4 Pond Sealer is a deep bonding plastic coating for all cement rendered ponds.

G4 provides a tough, durable but flexible coating and being moisture hardened it can be applied to slightly damp substrates, although the cement render must be dry enough to be porous.

G4 Pond Sealer is available in G4 clear translucent finish or in Black.
