What is Lo-Chlor Leak Sealer?

Lo-Chlor Leak Sealer is a compound that has been developed to help seal minor cracks and leaks in swimming pools. A leaking pool is every pool owner's nightmare. Lo-Chlor has developed an easy way to plug minor leaks. 

How does Leak Sealer work?

Leak Sealer has a very high pH (about 12) so when you add it to your pool it takes on the pH of pool water (between 7.0 and 8.0). It now no longer functions as a liquid and starts to solidify in the presence of oxygen at the site of the leak. To ensure best results, please follow the instructions outlined below. 

Did you know...?

  • Lo-Chlor Leak Sealer is sold in more than 25 countries around the world
  • Lo-Chlor Leak Sealer is the fastest selling and most popular specialty pool and spa chemical in Spain and France
  • Lo-Chlor Chemicals distributes more than 20,000L a year of Leak Sealer to all corners of the globe.
