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

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.

Worked great to fill a penny size whole on my bathtub. Easy to use and hardened as expected. Solid stuff!

Worked great and stopped the leak! Would be nice if this came in a resealable bag or something to use later. Easy to use

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.

Don’t be fooled. This stuff absolutely is not usable under water. However, if your pool is drained and you need to seal some cracks it will work and sets very hard in a few hours but you will have to work with it if it is the slightest wet coming from the crack. Totally worthless underwater. I can’t believe they claim that.

We discovered a tear on the side of the steps of our inground vinyl pool liner last year and the vinyl patch kit held it for about 10 months. The hole grew larger so we wanted a longer lasting fix. My husband used this pool putty to wedge behind the hole (about 1.5 times the size) and used a piece of Flex Seal tape to cover it until it cured. The next day the putty was rock solid and leak dye showed no water going into the hole. He removed the tape and covered the hole with another piece of vinyl patch so we have twice the protection of any water getting through. Great solution that really worked and saved us thousands on the cost of replacing the liner!

Bought this for a leak in my pool. Wouldn’t stay on under water (which is literally what it is for” just kept falling off the surfaces and when I put it on the crack in the pipe it just fell off the pipe and ended up hardening on the ground underneath the pipe.

Great for waterproofing, must apply quickly
