Sellador de silicona negro para acuarios - cartucho de 10.2 onzas líquidas

Easy to use and it lasted a long time

I didn’t use it yet, but I’m sure it is very good

works really well, aside from the horrible smell it gives off so I had to turn on fan when doing my enclosures.

Works great but smells strong. Use in a well-ventilated room. I would but this again for another vivarium build!

I used this when reconditioning my 2006 50 gal aquarium, which has now been setup for a year after application. I used the clear, it's none yellowing and it's still mostly clear. It's actually mostly opaque in the thicker areas and clear in the thinner feathered out areas. It's easy to apply, well maybe not as easy inside of an aquarium, you need to move quickly and not touch the same areas twice. You may also need some paint thinner or similar solvent based thinner to clean up any mess. It's best to just let it dry, and use a new razor blade to scrape any excess off. Just make sure everything is prepped and very clean prior to application. One tube was plenty for the tank, I used 1" blue tape helping with straight lines. It's not necessary, but it does help make things look better. Cures

I used this to water seal some spray foam I put in my geckos 🦎 tank. The product dried pretty quickly for the application I used it for. I cut and sanded the spray foam so The absorbent product I put it on might have been why it dried so quickly. I also didn’t want the glossy look that you get with product so I tried to dust it with some dry soil, but half was already dry & to had to put another layer to get it tacky enough for the dirt to stick on there. This is not the main use for the product, but it works and my DYI project turned out great! And I have a happy gecko, a humid tank and no soggy decor, so I’m satisfied with this product and will use it again if I ever need to!

Before you throw away the shipping box, make sure to check for the nozzle. It comes loose in it's own little bag. I almost missed it as I had several other items in the box. The nozzle already has a hole in it to start, which I imagine would work nicely for traditional caulking means. The tube of silicone itself was easily opened above the threads with a razor blade.I feel it is important to note, I used this in the construction of a background for a reptile enclosure. It was applied over cured spray insulating foam and then coated with eco earth. If this is your intended purpose, make sure you shave off the skin of the foam, it'll give better adhesion. I used about a tube of it in a 20 gallon long.If you are able to, I would definitely use this outside and then keep your project outside …

Only giving this product 4 stars because of the terrible smell. I've used clear silicone before, and it did not have such a strong smell as this product. I opted for black as I was using it to build a dart frog terrarium, and if any if the soil washed away, I would prefer to only see some black spots in the background. It took literally 4-5 days for the smell to disapate. Do not apply this product in an area where people or pets are forced to breath near, until it has cured. I built my terrarium down in my cellar, with the back door open, and fans on, and I still had a headache for days due to the smell. The smell even seeped upstairs!That being said, the product worked well! I siliconed heavy peices of driftwood, and also rocks to my tank, and nothing has budged since! After foaming in …
