How do I get pond liner patch to stick? I drained a half-barrel with a
leaky liner and bought some of the really sticky one-sided patch to
cover a hole. I scrubbed the liner and let it dry, applied the patch,
waited a few hours, and filled the barrel.

It's been a couple of weeks and the barrel is leaking again. I drained
it and found that the patch is coming off.

I'm not sure what kind of liner I have. I think maybe its EPDM. I
bought it as a "remnant" at a pond store to line the barrels. It's
black, fairly flexible, and has sort of a woven texture to it.

Thanks for any help.
