Size: 1 qt


The Ultima Watertite is a dual-action leak seal formula that is compatible with all sanitizers. The formula causes the tiny particles in the pool water to expand far beyond their average size. The second part of the dual action formal is when the particles become large enough, they absorb the semi-soluble portion of the formula, which then makes it insoluble and waterproof.

  • Dual action formula stops leaks
  • Compatible with all sanitizers
