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.

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...
