Had a concrete pond that had been sealed 3 years ago with an epoxy paint for ponds. I meticulously caulked all the cracks and pits to assure a good bond and seal. It worked great for 3 years. The crack broke through the epoxy paint. I thought I could use flexseal to seal it. I chose clear, so it would be inconspicuous. WRONG! It sort of worked, I'm using the pond, but, it looks like some kid was spraying glue all over the interior... spots here there and everywhere. It sealed the bottom ok, but, evidently the sides are still leaking as I can't fill it more than 3", just covering the pump. Anything deeper (pond is 6" deep) water just seeps out to the 3" level. The can does say "temporary seal only." Bottom line: My gut told me to re-caulk the crack, sand the surface of the whole pond and re-coat with the original epoxy pond/pool seal. That is what I will be doing next Spring. You just can do short cuts anymore!

not as good as I hoped
The good: easy to apply to surfaces using the spray can. The bad: takes too long to adhere to surfaces and dry. Ive been waiting over four days now and its still not completely set up all the way. It is still tacky and peels off. This is the first time I’ve tried this product so it’s only been less than a week. It did not meet my expectations. Please hit thumbs up if this was helpful.

Works as it says but not much paint in the can. One can was not enough to get good coverage on 3 wooden crates used as planters that I painted white with regular paint first. A couple of the slats were cracked and Flex Seal sealed the cracks.

My new sealer
Customer review from logo
I received this a few days ago. I was anxious to try it out. I decided to try and seal around my vent pipe on my roof because it seems to be leaking a little It was very easy to use just spray around and make sure you cover it all. I will be getti g more to do other projects around my house. It has rained so I am thinking it worked. [This review was collected as part of a promotion.]

Not Completely Clear
Customer review from logo
Flex Seal Mini was extremely easy to use (although it does drip a bit). I imagine that the one where you brush it on is easier to control. This is the spray can one. I am including pics of the directions and of what the spray looks like immediately and then after it dries. I used it to fix a leaky pipe under my kitchen sink. The pipe is no longer leaking and I probably will have to get it replaced at some point, but for now, Flex Seal did what it says it will do. [This review was collected as part of a promotion.]

Our community has steel park benches which had begun to rust & lose some of the original finish. The typical rust inhibiting spray paints did not provide a durable finish. FlexSeal went on easily,and once dry, provided a great finish. An added benefit is that even after sitting in the hot sun, the new finish remains cool to the touch. I'd like to suggest that FlexSteel consider formulating a dark British Green color that would correlate with many metal garden accessories on the market.

I didn't use this to seal my house, I used it to repair a 2 meter ham antenna. worked very well to reinsulate the radiator and ground plane separator. I haven't seen any corrosion due to this product, so maybe this is the last time I have to take the antenna down to clean and recoat it.
