Pool Putty, 17.6 OZ, 2 Part Epoxy for Leaks Underwater or Above, Multipurpose Sealer for Crack Repair, Tile, Fiberglass, Concrete, Cement and Other Surfaces

Simple to use. Fixed my Marcite repair took some time to patch up underwater. Once it bonded, my pool patched nicely even with periodic brushing and weekly scrubbing. Added some color to the epoxy mix to match marcite color. Pool plaster patch (before and after). The patch will harden under water and took less than 24hrs to cure. Patch is seen at the bottom of the pool below the center planter.

Had a small leak in my pressure side coming from my cleaner. Added a little of this and it’s held up great so far, no leaking through 8 days. Will update if anything changes. Heck of a lot cheaper than replacing the whole cleaner!

Very shortly after I got this, I used it to repair a large outdoor concrete planter. Note this is very slow curing so you have plenty of time to work with it, but it takes about a day to become solid. Otherwise, It was pretty easy to work with, and the repair held up very well for many months and it still almost as solid as the concrete around it. However, last week I tried to use it to repair a smaller ceramic pot. Did everything I did the first time. A little more than a day after I made the repair on the second pot I lifted it, and the pieces just fell apart. The epoxy was still a little bit soft. The conclusion is that once you open this, you have a pretty short window to use all of it. Otherwise it’s not going to be any good. So unless you have a large area to repair right away, you might want to save some money and buy smaller packages of epoxy putty.

Over paid a couple of pool guys to find a leak on our pool. All they did was seal every crack the found using a similar product. However, they missed a few spots by the stairs. I bought this product to complete the job. It was easy to use; equal parts and squeeze and mix them together until the texture is consistent. Then you’re ready to go. Sealed everything they missed and the material stuck to the existing tile grout and filled the cracks in completely. It hardens fully after a day underwater. Price is reasonable and comparable to the blue ones I bought from Amazon a couple of years ago. But I like this one better as it completely hardens and stays put where you place it.

Terrible product

No es buena calidad

Its good stuff! Used pool putty in the cylinders in the past, and this is very similar in consistency and performance, and seemed a lot better price when I bought it.

There is a 3-4" stress crack in our hot tub. We tried tape, and two other products, but a leak continued to develop. We used this product and it took a few attempts, but it has now held water for about a month without any issues.It seems to work better when the hot tub is already heated - we initially put it on and let it cure when the hot tub was empty, but it cracked when we added water. At this point, we filled the crack again and immediately added water. It cracked once again, but we continued to fill the cracks until there was no more leak. The fix isn't pretty, but it's functional.
