Marlig® Fix-A-Leak is a concentrated liquid formula designed to permanently seal leaks in shells, plumbing, fittings, and filtration systems in pools and spas. It is effective for holes up to 1/8″ in diameter and can be used across multiple spa materials. This 32 fl oz size is formulated for typical spa sizes and heavier leaks in pool systems. It works safely with salt chlorine generators, pumps, heaters, and filters without damage. The sealant sinks to the lowest point and must be kept in suspension during treatment for full effectiveness. It cures in 24–48 hours, after which the system can return to normal operation. Show more
