Review: Stops leaks fast - I used the sealant for a crack in a hot tub. Having already used a different product, I wasn't convinced that this would work and we would have to drain the tub and fibreglass the crack. After mixing the putty I applied the putty to the inside of the tub underwater, and it did just what it should and stuck to the tub. It was easy to mould and I was able to fill the crack. The leak stopped without having to apply it on the out side of the fibreglass, although I did for extra bonding. Thoroughly recommend this product, wear gloves when mixing, I didn't and the chemical burns a bit. I couldn't get gloves to enable me to apply this underwater, but would find some in the future. Excellent product.

Easy to apply and has worked well at stopping the leak so far

### ⭐⭐⭐⭐⭐ Does the job even better than expected
*by S***N on 12 August 2025*

This stuff does exactly what it says on the tin. Have a crack in my toilet cistern top to bottom and it was leaking. Google said I’d have to replace the cistern. Found this and thought I’d try it. Emptied the cistern (though I don’t think you even have to) took 30 seconds to break some off and mix it in my hands. Applied it like putty to the crack. Waited an hour and it was hard and set. Refilled the cistern and not a sniff of a leak and this was a few weeks ago and it’s still perfect. I’ve since even used it (as I had loads left) to fill a hole where a top fixing blind fell down then drilled right into it, wall plug in and the blind is back up and stable. Poly filler wouldn’t have held it. Not often I review stuff but it’s done the jobs for me, and better than expected.
