Flex Seal Liquid

[PDRed302]

Just don't try to mix the spray and liquid on the same project...

You could ask me how I know this is a bad idea, or follow just the link in my signature "345 rebuild". Spoiler alert; big failure, huge mess and a waste of time.

While the liquid may actually be a good product, after the time and money I wasted using it, I won't be using it again.

If you want liquid rubber, then try a product called "Rubberize it", I've used it in the past with great success, I'm also fairly sure you can get it in different colors.

Just test it with some goldfish.

I have intention of doing just that. will let you know

Bump. My aquarium canopy started molding I'm thinking about giving it a good cleaning and apply some liquid flex seal. Any concern? Will it harm the fish if vaporize water drips back into the tank?

i used flex seal to fix a leak in my sump.

I have not had one problem. While it was curing The fumes were pretty bad.

Hope that helps

Hello everyone This is my first post.

I've been a fish enthusiast for close to 10 years.
I currently work with Lumber, so decided to build my own fish tank stand for nearly free out of wood.

So I found this post about flex sealing a wooden aquarium stand & I did it!

It was a great experience and is working out well so far. I've had the tank setup for a little over a month.

Here's some pictures for the curious.

I used liquid flex seal only. Not the aerosol can.

Looks good, Bro!

I just used polyurethane for my stand, I had built 7 years ago. Still solid after all these years, even after a number of water change floodings.

My First Big Boy Tank!

Picked up this used 180 gallon from a member of a local fish forum in August . Tank has been stored outside, standing vertical on side exposed to direct sunlight. Glass appeared intact, but the external silicone seal is shot. For $100 I was willing to take a gamble, especially since this...

I know this is an old thread, but I just found it... I would like to add my 2c.
I don't know about the liquid form of Flex Seal, but the tape does not work at all for aquatic use. I had a small hole in my pond liner. I cleaned the area (the water level had drained and evaporated below the hole). I applied the tape (thick stuff which likes to stick to itself). Once the water touched it, it lost all stickiness. ALL. The sticky side became slippery.

Wow that sounds like an epic fail for the tape form at least.

To catch up this thread with my experiences with flex seal, I find that liquid flexseal has a few good qualities for aquaria use:

-It is easy to use and apply. True one step application.
-it is indeed non-toxic to fish once cured ime. I've used it in fresh and salt in 3 tanks with no apparent negative results. Please note I have not tried to keep coral in any of these tanks.
-it looks rather nice when cured. My latest build has the bottom and manifold panels coated with flexseal black. Gives a sort of "slate" appearance.




I plan to use it more in this capacity in future builds simply since it's available locally and seems to work for cosmetic purposes. I do not recommend it for structural sealing. My plywood build using only flexseal (minimal framing, no fiberglass) only lasted around 6 months so i consider it more of a durable aquarium safe coating than a sealant.
