I applied Pond Shield and my pond still leaks. What is wrong?
Simply put, you missed something. After your initial coating is applied, you need to go back and inspect the entire surface are for flaws in your application. Ares like cracks, crevices, voids, concrete showing through and any similar areas need to be corrected before you call the job finished. Once you have successfully applied a 100% coating to the interior of your pond, it will not leak.
