- Used to seal concrete ponds
G4 Pond Seal is a moisture cured polyurethane which forms a non-porous seal on concrete rendered ponds, G4 uses the moisture in the air and the render to harden, it can be applied to slightly damp surfaces, but it is important that the render is sufficiently dry to be porous so as to enable the first coat of G4 to bond and obtain a mechanical grip,G4 can be applied in poor weather conditions, high humidity and at temperatures down to zero degree's.
As a general rule the pond should be constructed to be structurally sound since the G4 only provides the waterproof seal, on no account use a P.V.A based sealer to seal or prime any surfaces, these materials can contain ammonia and also stop the G4 from adhering to the render.
- G4 Standard - 3 coats = 550g per sqm for the three coats
