BenA Posted August 12, 2021 Share Posted August 12, 2021 I need to attach 2 pieces of wood. Tried superglue but it didn't work, Is epoxy glue safe? Thanks Link to comment Share on other sites More sharing options...
Taco Playz Posted August 12, 2021 Share Posted August 12, 2021 I wouldn’t try it just to be safe, although you probably could do it. Instead I would get some of this https://www.google.com/aclk?sa=L&ai=DChcSEwjDo_v-qqzyAhXGbm8EHUXxBLIYABAEGgJqZg&ae=2&sig=AOD64_00zjPhEKUImU_8czpeR-THZXACGw&ctype=5&q=&ved=2ahUKEwiB7Oz-qqzyAhWXPM0KHYgmAqkQ5bgDegQIARA-&adurl= Link to comment Share on other sites More sharing options...

Gator Posted August 12, 2021 Share Posted August 12, 2021 BenA; There is a type of epoxy glue made for underwater applications such as attaching coral frags to rocks or whatever. This epoxy is a putty that you knead together to activate and is pretty strong. If your LFS also sells saltwater fish, I'll bet that they'll have it, an LFS that doesn't sell saltwater fish may also have it. Why didn't the superglue work?

I second this. Just do your research. Majority of big fish store tanks are sealed with silicone. 1 Link to comment Share on other sites More sharing options...

Patrick_G Posted August 13, 2021 Share Posted August 13, 2021 Did you get the gel super glue or the liquid? The gel is much easier. 3 Link to comment Share on other sites More sharing options...

I used gel superglue and for whatever reason it has never hardened/dry. My LFS does sale marine fish so I will check about the patty. I wanted to use a DIY glue but didn't feel comfortable about it.

I thought about household silicon, I don't understand why clear silicon for home use can't be used for an aquarium but I don't want to take the risk.

Home improvement stores have about 15-20 different silicone products for different jobs. Clear 100% silicone can be had at these places for ~$8 a tube. It's what I use. Just gotta make sure there are no additives. 2 Link to comment Share on other sites More sharing options...
Gator Posted August 13, 2021 Share Posted August 13, 2021 BenA; Why pay a high price to buy a small tube of silicone glue at your LFS when you can go to the automotive department at your local Wally World to buy a much larger tube of the same silicone for about the same price. As long as it says 100% silicone, it's the same, and you can still get the silicone in clear. The automotive silicone is the only silicone I use except when I'm repairing an aquarium, then I use a caulking gun to apply clear construction silicone, it's the same silicone that aquarium manufacturers use to build aquariums. So save yourself some money. Sincerely Gator 2 Link to comment Share on other sites More sharing options...
BenA Posted August 14, 2021 Author Share Posted August 14, 2021 Ordered from Amazon and will have it Monday. In the UK we can't get the GE Silicon but found another, BOND IT CLEAR HA6 RTV Silicone Sealant Marine Aquarium Safe Water Fish Tank Adhesive : Amazon.co.uk: DIY & Tools Thank you all Link to comment Share on other sites More sharing options...
ArtemisCai Posted August 15, 2021 Share Posted August 15, 2021 I just bought these and used them to bond rocks together for my aquarium. I got them on Amazon. Link to comment Share on other sites More sharing options...
Gator Posted August 15, 2021 Share Posted August 15, 2021 ArtemisCai; Both of these are well and good, but you paid an arm and a leg for each of these, including the shipping. The tube on the left is 3 ounces while the tube on the right is 2.7 ounces, and both will do well for the applications you mentioned. My points are that you can get a larger tube of the same quality silicone in the automotive department at your local Wally World and you can get an even larger amount of the same quality at your local hardware store. With this you'll also need a caulking gun that allows for a precise application with less mess, we don't like a mess in our tanks.
