Hi Folks,
We've been putting pond armor in an upper pond for years but every 2 or 3 years it fails and it begins to leak. Now I'm going with a new product Pond2000 which they claim can last 10 years but I'm having a heck of a time removing the old layers of Pond Armor.
The Koi are in the lower pond.
I've tried sanding, wire brush, scraper, all met with limited success. I'm wondering if there is a solvent I can put on to remove it and get to the bare concrete.
Here are some pics
