Pond Shield Armor SKU-GRAY-QT-R Non-Toxic Epoxy Paint, 1.5-Quart, Gray

I gave this 5 stars, but I feel like the suggested coverage is on the high side, so maybe 4 1/2 stars. However if you have a pristine smooth surface that you're coating, maybe it'll cover like they say. We were coating concrete, and so it the coverage was definitely reduced. The coating looks good however, and brushed on pretty good. We did 2 coats. Like many other reviews state - mix only what you can apply in 15 minutes, and not a drop more. I've never seen anything harden so fast... One sec it was like latex paint, then within 15 seconds it was like tar on the brush, and about 30 seconds later my brush was permanently glued to my paint tray. Would I recommend? Absolutely, just order about 30% more than you think you need. And work fast. No, work really fast. Looks great, and sealed our leak. Thank you

Worked perfectly for the fountain we had that was too porous to hold water. Great price for such a quality option. No leaks now and fountain will last many more years than any other cheap fix we could have done. Instructions were great. Had no issues making several batches over a few hours and 2-3 coats were done on all surfaces for the perfect finish. Be sure to use alcohol and this product will absolutely cover the m2 mentioned on the tin. Would order again!

I purchased the Pond Armor Gray 1.5-Quart Kit (SKU-GRAY-QT-R) to seal a custom-poured concrete water fountain feature. I wanted an alternative to ugly rubber liners that crease and fold. After a full cure cycle and testing, this two-part epoxy coating performs flawlessly as a heavy-duty waterproof barrier, but it is a highly unforgiving product if you try to cut corners on preparation.Preparation & Surface CompatibilityThe Prep Work: You absolutely cannot skip the acid-etching or mechanical grinding phase if you are coating concrete. I etched my fountain base with muriatic acid, rinsed it thoroughly, and let it dry completely.Self-Priming Power: The self-priming chemistry works precisely as advertised. It grabbed onto the porous stone and concrete substrate with an incredibly aggressive mechanical bond, requiring no separate baseline sealer.Mixing, Application, & Pot Life RealitiesThis is where most negative reviews likely originate: this is a true space-age polymer epoxy, not standard outdoor paint.The Flash Time: Once you mix Part A and Part B together, you have a very narrow working window (roughly 20 to 30 minutes depending on ambient temperature) before it starts to kick and harden in the bucket.Application Tip: Do not try to apply the entire 1.5-quart kit at once unless you have a helper. Mix it in small, measured batches. I used a high-quality nap roller for the flat basin floor and a stiff-bristle brush for the vertical corners. It flows thick but self-levels beautifully to an eggshell/gloss finish.Curing, Coverage, & Biological SafetyThe Footprint: The box claims coverage up to 60 square feet at a 10-mil thickness. If your concrete is highly textured or porous, expect that coverage to drop to around 45–50 square feet. Plan on buying a touch-up kit or a second box if your dimensions are right on the line.Aquatic Safety: The 24-hour rapid cure time is exceptionally convenient. After letting it sit for a full day, I did a water flush. Because it cures to a completely non-toxic, inert plastic state, it did not alter my water pH levels or harm my goldish and pond plants. Algae wipes off the cured gloss finish with a simple sponge brush.Final VerdictThis is an absolute 5-star waterproofing system that completely seals hairline concrete cracks and withstands freeze/thaw shifts. However, it gets a warning for novice DIYers: read the instructional sheets twice, mix in small segments, and respect the chemical clock.

I have an old concrete pond and waterfall in my backyard. I had drained it and stopped using it because the concrete had small cracks and it leaked so badly. A membrane style liner isn't practical due to the shape of the waterfall. I was about to have it demolished....then I discovered Pond Shield, which came highly recommended online. Three packages did my entire pond/waterfall. See the product description for coverage recommendations. It's been almost a year, and there is zero leakage, and my waterfall runs 24/7/365. Pond Shield is a two part epoxy that you mix and apply. Clean the substrate thoroughly, and use an etching acid if the surface is smooth. Then mix it up according to the instructions and apply with a disposable brush or small roller. The one caveat is to mix up small batches....no more than you can apply in about 5-7 minutes. It begins to harden quite quickly. If you mix up too much at one time, it forms a skin, gets clumpy, and cannot be used. And it gets extremely hot if it sits for long. Ask me how I know! The instructions warned of this....and I quickly learned to follow them. Do so, and all will be well. I'd mix up a cup or so at a time until you get a feel for it. Wear thick rubber gloves, eye protection, and old disposable clothes. Pond shield comes in a variety of colors. I chose gray as it compliments the natural stone of my pond. This is a fantastic product, and I strongly recommend it.

First time I have used this to paint my concrete above ground pond. Great product that was easy to prepare and use. Nice finish as well. Very happy with the results!
