5.0 out of 5 stars Dependable Sealant and Adhesive: A Review of J-B Weld 31319 Black RTV Silicone Sealant
Reviewed in the United States on February 29, 2024
I recently had the opportunity to use the J-B Weld 31319 Black RTV Silicone Sealant and Adhesive, and I must say, I am thoroughly impressed with its performance and versatility. As someone who frequently tackles DIY projects and repairs around the house, finding a reliable sealant and adhesive is essential, and this product certainly delivers.

One of the standout features of the J-B Weld 31319 is its exceptional durability. Once applied, it forms a strong and resilient bond that withstands a wide range of environmental conditions, including temperature fluctuations, moisture, and vibration. Whether I'm sealing gaps in plumbing fixtures or bonding materials together, I can trust that this silicone sealant will hold up over time.

Another aspect of this product that I appreciate is its ease of use. The nozzle allows for precise application, minimizing waste and mess during the sealing process. The consistency of the sealant is ideal—not too runny, yet smooth enough to spread evenly and fill in cracks and gaps effectively. Cleanup is also a breeze, as the excess sealant can be easily wiped away with a cloth or sponge.

The black color of the sealant is a nice touch, especially for applications where aesthetics are important. It blends seamlessly with dark surfaces, providing a clean and professional finish that enhances the overall appearance of the project.

Furthermore, the versatility of this product makes it a valuable addition to any toolkit. Whether I'm sealing leaks in automotive components, repairing household appliances, or even crafting custom projects, the J-B Weld 31319 proves to be a reliable solution time and time again.

In conclusion, I can wholeheartedly recommend the J-B Weld 31319 Black RTV Silicone Sealant and Adhesive to anyone in need of a dependable sealant and adhesive for a variety of applications. Its durability, ease of use, and versatility make it a standout product in its category, and I will certainly continue to rely on it for all my sealing and bonding needs in the future.

The seal on the backend broke causing glue to shoot out the wrong end. Used as much as I could on a few different things. The glue itself works amazingly well. Just bought another 2 tubes.

Used this to fill in holes on my homemade solar charged 12v battery pack. Squeezes out of the tube easily and seals very well but is nice and thick. Color is clear and clean. There's not an extremely overpowering scent. Seems like it will work well and last a long time.

4.0 out of 5 stars The good, the bad, and the sticky.
Reviewed in the United States on November 5, 2024
Overall, this product works well and is safe for aquarium use, which is great peace of mind for fishkeepers.

The Pros: It's definitely aquarium-safe, and the set time is accurate as advertised.

The Cons: Be aware—it has a strong chemical smell. While it's expected for silicone, it's quite intense.

The Caution: The silicone is sticky, which is normal, but the real issue is the packaging. The tube is made of metal, and if you squeeze or roll it a bit too hard, it can split open, leading to silicone spilling onto your hands. I’d recommend wearing gloves to avoid a mess.

In terms of functionality, I would recommend this product for aquarium applications. However, the packaging could be improved, as I ended up losing a fair amount of silicone due to leakage.

I needed some silicone to cover some cable holes and it worked great. Easy to squeeze out and get into tight places with the cone tip. No mess at all and stored away for the next use.
