Pool and Spa Leak Sealer
Seal your leak in your pool or spa with LO-CHLOR Leak Sealer!
Advanced formula that is ideal for fixing minor leaks in pools and spas
Seals minor leaks in concrete and fibreglass pools
and spas. 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. This advanced Leak Sealer can seal leaks losing up to 1" of water per day. No need to empty pool or spa.
Fast acting - usually stops leaks in 24 hours. 1 qt bottle. One quart treats 15,000 gallons pool water.
