Bonda G4 Pond Sealer Clear 1kg

Bonda G4 Pond Sealer Clear is a moisture-cured polyurethane, which forms a non-porous seal on concrete, brick or porous stone. G4 uses the moisture in the air and substrate to cure or harden. It can be applied onto slightly damp substrates. However, it is important that the substrate 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 0°C. G4 seals out lime. G4 will not seal concrete or lightweight blocks, these must be rendered before application. G4 Cannot be used on bitumen or pond liners.

Preparation: Ensure cement render is clean, dry and porous - highly trowelled surfaces are not advised. New render should be allowed to harden for 21-28 days depending on conditions. Reinforcing fibres in the cement must be burnt or sanded off before coating. Repair cracks and damaged areas.

Application: Apply first coat by brush, avoid thick coats, and allow to become fingerprint dry or dry enough to walk carefully upon, approximately 60-90 minutes, depending on humidity.
Apply subsequent coats following above instructions.
Do not allow longer than 4 hours to elapse between each coat. Normally 3 coats of G4 Standard are sufficient but on very porous or rough surfaces a 4th coat may be required.
Rain will affect uncured G4 so make provision for covering if rain is expected.
Allow to harden for 72 hours before washing down with clean water.

Coats: With Coloured G4 the first two coats are G4 standard followed by 2 coats of coloured G4. Follow instructions as detailed above.

Consumption varies slightly depending on porosity. On normal porous cement renders.
G4 Standard - 3 coats = 550g/m² (for 3 coats)
G4 Coloured - 2 coats G4 Standard = 410g/m² (for 2 coats)
- 2 Coats G4 Coloured = 400g/m² (for 2 coats)
