Application Hints:

INSTRUCTIONS FOR USE FOR GEBOLIQUID XL:

1. Determine the volume of water present in the heating boiler – see “water volume in heating systems”.

2. Shut off the connecting lines from the heating boiler to the radiators, by creating only a small circuit.

3. Filters and strainers must be removed.

4. Shake Gebo Liquid XL well and add undiluted via the heating filling valve into the heating boiler (1 litre of sealant to 100 litres of water) – see „dosing instruction“.

5. Bring boiler to an operating temperature of min. 60 °C. The sealant must remain in the boiler or in the small circuit for 4-5 hours at min. 60 °C. If the operating temperature of 60 °C is not achieved, the duration of the sealing process may extend accordingly (by several days). It is essential to ensure that the circulating pump operates continuously during the sealing process, because the sealant can only reach the damaged areas by circulation.

6. Fully open thermostatic valves.

7. Open the connecting lines to the radiators once more.

8. Thoroughly vent circulating pumps and radiators.

9. In order to prevent undesirable crystallisation, all working equipment and objects, which have come into contact with the liquid sealants, must be rinsed thoroughly with water.

10. Once the sealing process is complete, reinstall strainers and filters.

11. The sealant can remain in the system.

geboliquid - two-component sealant for heating systems

geboliquid is an innovative silicate sealant based on silicates, developed to quickly and permanently seal leakages in the water-bearing parts of heating systems from the inside - without any time-consuming dismantling or drying work. The geboliquid Micro, S, L and XL variants are each tailored to the amount of water leakage: from a maximum of 10 litres per day (Micro) up to 800 litres per day (XL). This means that the right solution can be found for almost any size of damage. The product range is supplemented by geboliquid Clean, a cleaning concentrate for removing lime, rust and sludge from the heating system, and geboliquid Protect, an anti-corrosion agent in accordance with VDI 2035. Both products are compatible with common materials such as steel, aluminium, copper and plastics and ensure reliable and permanent operation of the system.

geboliquid is the practical solution for skilled tradespeople who want to repair heating systems economically and protect them sustainably at the same time.
