Sealing pool pipes: remove all nozzles/vents and close all pool water intakes. Bypass all filter systems. Circulate the mixture in the pipes for 48 hours using an external pump, possibly with at least 1 bar of pressure. After sealing, empty the pipes and rinse thoroughly with water. Reassemble the nozzles/vents and reopen all the water intakes of the pool.
1-2% (1-2 liters of sealant to 100 liters of water) for sealing swimming pool pipes.
