Lo-Chlor Leak Sealer – Advanced Liquid Formulation for Sealing Minor Cracks & Leaks in Pools and Spas

Lo-Chlor Leak Sealer is the ideal solution for pool and spa owners facing minor cracks and leaks in both pipework and surfaces. This advanced liquid formulation is designed to seal leaks efficiently without the need to drain your pool or spa. It can handle water loss of up to 3.5cm per day in a 50,000-litre pool, and usually stops leaks within 24 hours.

This product is not suitable for repairing leaks in vinyl liner pools, and larger defects may require professional plumbing or maintenance. When using Leak Sealer, it is important to remove any automatic pool cleaners from the water and ensure that the solution does not pass through the filtration system. Exceeding the recommended dosage should be avoided for optimal results.

One litre of Leak Sealer is sufficient to treat up to 50,000 litres of pool water. The formulation works by adapting its high pH (approximately 12) to match your pool water’s pH (between 7.0 and 8.0). Once added, it begins to solidify at the leak site in the presence of oxygen, sealing the crack effectively.

Lo-Chlor Leak Sealer is sold in more than 25 countries and is the most popular specialty pool chemical in Spain and France. Over 20,000 litres of Leak Sealer are distributed globally each year, helping pool owners worldwide maintain their pools with ease. Always follow the label instructions for the best results when using Lo-Chlor Leak Sealer.
