Product overview
Butyl Rubber That Chemically Bonds To Your Pond.
PondPro 2000 is built on a flexible butyl which is solvent based, allowing for significantly higher elongation and tensile strength than other pond products. As it cures the product will literally chemically cross link and bond to the surface it is applied over.
That is why it goes over existing EPDM liners, fiberglass, vinyl, concrete and any third-party coating that has already failed, without stripping anything back and without the need for a primer. It just cannot be applied over silicone or PVC. A thirty-year history of success has made it the choice of thousands of pond owners.

No more loss of water, for the first time
Put Pond Pro 2000 on the liner of our waterfall pond. Works wonderful, no more loss of water for the first time. Our contractor will not use a liner without putting Pond Pro 2000 on it to seal.

We were sceptical about one coat
We make it a habit of testing any product first before we apply it to our customers ponds. We were somewhat sceptical about it being a one coat application, as the other products we use require a primer. It did what it said it would.

Simple to coat, even at 72
As a first time user of your product I am so pleased at how simple it was to coat our pond. Adrienne helped me get the seal off the cans and answered a couple of questions. The pond looks amazing, and my children and grandkids are impressed with my results. I am 72.

The calculator told me six gallons and six gallons is exactly what the job took. I have ordered enough coatings in my life to appreciate not guessing.

I could never find the leak. Sealing the whole liner was the answer nobody else was offering. Fish went back in the following week with no issues at all.

I saw after I purchased my PondPro materials that if I sent in my before and after pictures I could receive $25 back. Well, here you go. Thank you again, and it turned out great.

Our fish are thanking you
We had an artificial pond that leaked, and rather than replace the entire lining we were looking for a product we would not have to worry about fixing later. Our fish are thanking you.

The Questions Asked Before Every Order.
Still want to talk it through? Seven days a week.
855-788-5836How much product do I need?
One gallon covers roughly 40 square feet. Simply enter your pond's dimensions into the calculator above, and it will automatically calculate the total surface area, gallons required, and most cost-effective package combination.
Do I have to drain the pond first?
Yes. The surface has to be clean and dry before you coat it, so the pond is drained and the liner or shell washed down. Fish go into a holding tank for the day, and back in 72 hours after the coat has fully cured.
Will it stick to a coating that already failed?
Yes. PondPro 2000 chemically bonds with the surface beneath it rather than simply sitting on top, allowing it to be applied directly over most existing coatings — even failed third-party coatings — without stripping or primer. It adheres to virtually all surfaces, with the exception of PVC and silicone.
What if it rains before it dries?
Assuming temperatures are 55°F or higher, PondPro 2000 becomes waterproof in approximately 4 hours and is fully cured within 24 hours. For best results, wait 72 hours before refilling the pond to allow the coating to fully set and perform as intended.

Do It Once. Do It Right. Then Stop Worrying About Your Pond.
Price is often the first thing people consider. But when you compare the initial cost with the expense and hassle of repeating a cheaper repair every few years, the long-term value becomes clear. PondPro 2000 is an investment in doing the job right the first time.
