J-B Weld 8277 WaterWeld Underwater Epoxy Putty - 2 oz by J-B Weld

Used it to fill a crack in my RO unit. It's really safe for potable water tanks and does a great job

Used it to seal a persistent leak along the edge of tiling abutting a lift well wall that was getting damp. It worked well .

I was used this product on pvc water tank leak repair. But after applying this pest leakage not repaired. Not useful for the product. I don't like.

घटिया सामग्री है मैं तो फंसा कोई भी मत फँसना pvc पाइप पे काम नहीं किया 900 रुपए गए पानी मे

Bought this to repair a cracked external 90 degree drain pipe. Easy to use...just cut of the amount required & mould together on you fingers. I recommend wearing some protective plastic / rubber / silicone gloves as this suff stick to you like a limpet... Easy to mould and apply but be quick...once mixed you can actually feel it starting to set as you use it. Full Setting time is dependent on temperature but mine went hard within 15 minutes at 15C. Once set, it is never goes 100% solid like some other epoxy products so keeps a bit of flexibility (95%) and doesn't go brittle. I've also found it useful for filling oversized holes in various materials and re-drilling for screws and rawplugs. Highly recommend this product if you have a water pipe needing some long term or temporary repair and more...it works...

Ich habe den J-B WaterWeld Epoxyd-Kitt für meine Pool-Filteranlage benutzt, weil am Deckel ein Riss war und ständig Wasser austrat. Obwohl die Anleitung nicht auf Deutsch ist, war die Anwendung absolut selbsterklärend: Stück abschneiden, kneten, auftragen – fertig. Meine Erfahrung: Sehr einfache Anwendung, man braucht kein Vorwissen. Nach dem Aushärten absolut dicht – 100 % erfüllt, was ich mir erhofft habe. Ideal für Notfälle im Pool- oder Sanitärbereich. Wichtig zu wissen: Das Ergebnis sieht nicht unbedingt schön aus, eher wie ein grober Flicken. Wer Wert auf Optik legt, sollte das bedenken. Handschuhe sind Pflicht – das Material klebt stark und ist schwer von den Händen zu bekommen. Fazit: Der Kitt macht genau das, was er soll: abdichten. Für mich hat er ein teures Ersatzteil gespart. Klare Empfehlung für alle, die schnell und zuverlässig etwas reparieren wollen.

Works as advertised. Easy to use and waterproof.

Just what I needed

Tiny crack on a brazz nozzle in the garage needed mending. It's an old school, solid brass part so replacement is expensive and it hooks up to a water hose in the garage so I didn't want to waste money. Bought this on a whim, followed the simple instructions, put a layer over the crack and voila....it's fixed and holding up nearly five months later. Wear disposable gloves when working with this. It's a bit of a pain to take off after contact with the skin.
