Ultima Watertite

Unique dual-action formula that stops leaks for spas, hot tubs, pools and fountains.


Watertite leak seal formula uses a dual-action process in which tiny organic particles expand many times their size when added to water. These particles then absorb the semi-soluable portion of the formula, becoming insoluable and waterproof.
