Product details

Stops water intrusion in seconds and seals leaks in emergencies. Immediately ready for use on all materials. Can also be used in underwater areas.
Wax/fatty sealant that is immediately ready for use in an emergency on board such as water ingress and leakages. The sealant is applied directly to the damaged area by hand or pressed into the hole in an emergency. The inflowing water doesn't impere adherance to the surface and the leak can be closed up in seconds. Perfect for easily sealing cracks in GRP or wooden floors and leaky valves. After use, LEAK HERO can simply be wiped off with a cloth or scraper. It's no wonder why LEAK HERO should be carried in all emergency tool boxes on board.
Content: 625 ml. / Shelf-life 10 years

Tip: After application, the sealant can simply be washed off the skin with water and washing-up liquid.

suitable in temperate zones but becomes too soft in the tropics

These ratings are not really helpful. A product can only really be rated once it has been used. Here you should really create a choice with which this can be expressed. Hope I never need it and can therefore not say anything about the quality and satisfaction.

small leak into a boat
We had a small drip into the hull in the summer. tried to apply Sealant LEAK HERO. We put quite a lot on the hole, kept dripping through. The only achievement was that when it came to glassing the hole everything was greasy from the Leak Hero.
Then we bought an under water epoxy stick which worked like a charm.

Completely useless! LEAK HERO gives a completely false sense of security!!!
I had a very small leak at the bow thruster (2 drops per second), at most 10 cm below the waterline. Leak Hero didn't work at all.

Leak Hero gives a completely false sense of security!!! - Completely useless! Fatal in an emergency!

Completely unusable
A tiny hole in the bridge deck needed to be sealed because water had penetrated the electrical system underneath.

The product sticks everywhere, especially to hands, but not where it's supposed to.

Not in dry conditions, and certainly not in damp conditions. It's unthinkable if a serious leak were to occur and we had to resort to this extremely defective product. The can goes in the trash. Rating: 0 points; in my opinion, it's even a safety risk. It should be withdrawn from sale.

I also don't understand how anyone can give it a full score without ever having tried the product.

Reply from YACHTCARE
** wir bedauern sehr, dass Sie mit unserem Produkt YC Leak Hero in der Anwendung nicht die gewünschten Ergebnisse erzielen konnten. Wie Sie beschrieben haben, wollten Sie ein kleines Loch mit Fett verschließen. Dabei kam es jedoch zu einer unerwarteten und für Sie ärgerlichen Situation, da Ihre Hände stark mit Fett in Kontakt kamen. Wir verstehen, dass dies für Sie sehr unangenehm war und Ihr eigentliches Anliegen dadurch in den Hintergrund geraten ist.

Da es sich offenbar um einen sehr speziellen Anwendungsfall handelt, bedauern wir, dass das Fett in diesem Fall nicht die gewünschte Haftung entwickeln konnte. Grundsätzlich ist es so konzipiert, dass es auf nahezu allen Untergründen haftet und als Notfallhilfe dient.

Sollte ein Schaden wie ein kleines Loch bereits im Vorfeld erkennbar sein, empfehlen wir grundsätzlich, sich auch professionelle Unterstützung zu holen, um eine dauerhafte Lösung sicherzustellen.

Wir hoffen dennoch, dass Sie inzwischen eine gute Lösung für Ihr Anliegen gefunden haben.

I got this product in June 2020 and there is only one date in the bottom of the product and that is 03/2020. I believe that the validity period (5 years) starts from that and will end 03/2025. Hopefully I don't have to use this product...
