Rated 5.0 out of 5.0 by RetiredMCPO Does exactly what it says it will do
This product did exactly as it was supposed to do: it worked! We used it in a large koi pond that is a split level, shallow on one end, and a deeper pool on the other end, lined with a concrete bottom and sides. We have 10 large koi, and had a leak that we could not resolve with any other product. I don't have to describe the loads of work it takes to fix a leak in such a large pond. Emptying water into large containers to conserve water, transferring fish to other holding areas to keep them healthy, and then cleaning and prepping the affected area was a lot of work. But if you use this product exactly as described and recommended, you will get results that you only hoped you could have. We have had the pond as full as it should be, and not one drop of water is evident outside of it. The leaks have apparently all disappeared, and we now have the pond we had originally: completely a place pf peace and beauty, and no annoying and costly leaks.

The product stopped the leaking of my fish pond. However, the area coverage was not to satisfaction.

Rated 3.0 out of 5.0 by Carlos Recommended with strong reservations
This product is what it purports to be: a pond liner that can be painted on. But its directions are daunting, impractical in some ways, and it just plain doesn't work in one regard. By daunting, I mean very detailed, requiring painstaking steps that present many opportunities for failure, seemingly. By impractical I mean, e.g., one step has the user cutting a thin piece of plastic with a line printed on it that is supposed to be used as a application depth gauge. This would be very difficult under ideal conditions but working under a critical time constraint inside a concrete and stone pond when it's about all one can do to just apply the material, checking its depth with this crude tool is all but impossible. Also, the product was very hard to apply, quite stiff, not at all paint-like. Finally, this was to be applied to both the bottom and sides of the pond and rocks and the bottom is not flat but bowl-shaped. Instead of staying put before it sets up it runs down via gravity puddling up at low spots, creating wavy globs that are much thicker than needed—and of course thinner where it ran from. I only recommend this product with reservations. It works but with great difficulty and far from ideally.

Pond Shield is an excellent sealing product. I have tried colored and clear and both types have worked well. One caution is that it starts to set up rather quickly, so you can mix only as much as you can apply in about 15 minutes. I used it to seal a concrete based stream and small pond I built in our yard (see photo).

Rated 4.0 out of 5.0 by Jerry Clear epoxy sealer
I used the clear sealer to keep the same color scheme for my fountain. With clear, make sure you take care of all imperfections during prep. I don't think this product will ever were off. Make an application plan before you mix. My product started to harden up in my mixing container in about 10 minuets. The product also became very tacky on the fountain. Waited the allowed time per instructions, but this might have been too long. Keep checking the product surface. I probably didn't need a second coat anyway. All in all, it seems to be a very good, durable product, just a little pricey.

We have a concrete fountain that had a leak due to a crack and we could not use the fountain which is a shame as it is a beautiful fountain. Application of epoxy was a fairly easy process. We used a thinner to clean the surfaces and used it to thin out the epoxy as it was a little thick. After we applied the 2 coats to the fountain we let it completely dry. It gives a natural look after drying up and the fountain is holding the water well for almost 2 weeks now :-)

Rated 5.0 out of 5.0 by lynsi2 Restoring historic water feature
I bought the clear Pond Shield to use on a 1926 concrete water feature I found buried in the yard of our 1910 bungalow. I used a liner last year after digging it out, but wanted to have it restored to its original historic look and could see some hairline cracks in a couple of places. We put fish and plants in the pond so it was important that it be non-toxic. After using hydraulic cement to repair an obvious crack where the wall and bottom meet, I acid etched and scrubbed the walls and coated the pond with the clear sealant. I used the two step process for rough surfaces and applied the coating with an 8 Inch paint roller. The first coat soaked in so much that I could barely finish -- the pond has about 50 square ft of surface area -- but, as stated in the directions, I was able to completely coat the surface with a generous layer in the second coat. The weather was warm and dry and the first coat tacked up within just a few hours and I was able to do the second coat which also dried to the touch in about 4 hours, so the dry time varies a lot depending on the weather conditions. The finished surfaced has a "wet look" and is thickly coated. Once filled with water, the wet look blends right in. There was almost no odor and the product was pretty easy to work with so long as the instructions are followed carefully, which I did do. The pond has been filled for 24 hours and the water level is constant. This product is exactly what I had hoped it would be, and I am extremely happy with the results. It was particularly important to me that I not obscure and, in fact, protect, an impression of a NY 1926 license plate in the concrete that dated the pond -- which this product appears to have done perfectly.

Rated 5.0 out of 5.0 by Katie Excellent product
I purchased this to finish a raised, concrete koi pond. I etched the interior, and applied this product as directed. It sets VERY quickly, and is pretty thick, but sets like glass. I am buying another batch, as I underestimated my square footage, and missed a few spots. This is a reliable product, and much more pleasing than using a liner. Note to user: plan to finish your job in 15 minutes....it sets after this and your bucket and brush will be unusable.
