## Description

Product Description Gold Label Underwater Sealant 290ml black Box Contains Gold Label Underwater Sealant 290ml black

Review: Underwater sealant. - I have ordered several of these, over the years, I like to keep one in, as I have a pond with a butyl liner, this stuff is brilliant, says what it does on the tube. It's got me out of a scrape, when rats have chewed my liner a few times. Speedy and safe in the water with fish. Easy to use ,but I would recommend gloves as it sticks really well.
Review: Brilliant stuff - This is brilliant stuff, almost like liquid liner. I fixed a hole in a liner by applying it thickly (e.g. 2 mm thick) to a patch piece of liner, placing the patch on the hole, pressing gently around the side of the patch (not in the middle, there needs to a thickness of goo) and hey presto, done. I also tried a test piece and can confirm that this stuff is _very_ difficult to remove.

## Questions & Answers

**Q: It says on your product Safety that it's " Harmful to aquatic life with long lasting effects." .I don't understand.**
A: No idea about it being harmful. I used it to join two bits of liner that is under an artificial bog.

**Q: I have a 6 inch hairline crack in my fibreglass fish pond, will this fix it?**
A: I haven’t used this product for that purpose but it is supposed to bond layers together and seal joints so may be worth a try.

**Q: Has anybody used it on a glass aquarium. I need to do an underwater repair with the tropical  fish still in the tank.**
A: It will seal underwater and is non toxic. I have used it in a pond. The tube I had was black sealant though.

**Q: Can gold label  underwear  sealantI have  a hole  at the bottom  of my fish pond  do i have  to completely  drain  my pond to fix the  leak**
A: On the container it states that the glue will work underwater, which implies that you don't have to drain the pond.  However, the instructions also tell you to remove all mud, silt and algae.  To do this you have to lower the water level until the damage is exposed so that you can clean up around it.

### ⭐⭐⭐⭐ Black good. Clear not so good
*by N***E on 21 August 2024*

I have purchased both the clear and the black. For some reason the clear seems not to be so good to use for wet places or under water. The black I found to be much better. Strange! I have used them to seal edges around the pond and as an adhesive in the pond. Does a decent job. Wouldn't get the clear again though.
