We also have our Underwater Magic Putty™ 56 g in white for small underwater repairs, we recommend it for temporary repairs. Our scientific and field test team statement: our epoxy based product will stay flexible under the influence of swimming pool water but like other flexible epoxy products it will get rock solid hard and then brittle away over al long period. That's why we recommend epoxy for temporary repairs only.
Our technical support team of pool pro's and scientists is 365 days a year here for you to make your pool repair easy.
