J-B Weld 31310 All-Purpose RTV Silicone Sealant and Adhesive - 3 oz. - Clear

Used J-B Weld 31310 clear RTV silicone to seal a shower door and fix a cracked plastic light cover. It adhered well to both glass and plastic, cured evenly, and held up to water without peeling. No strong odor, and easy to smooth out. Only complaint: the tube split near the bottom halfway through, which wasted some product. The sealant works great

I recently used this silicone sealant for some minor household repairs, and it turned out to be a fantastic choice! 🛠️ The J-B Weld All-Purpose RTV Silicone Sealant & Adhesive is perfect for fixing leaks, sealing gaps, and even some automotive jobs. 🚗 🔧 The application process is straightforward, and the product works really well on a variety of surfaces, including glass, metal, and plastic. The sealant dries clear and provides a strong, waterproof bond that’s resistant to the elements. 🌧️ I especially appreciate that it doesn't shrink or crack, ensuring long-lasting durability. 💪 🧰 Whether you're fixing a leaky pipe, sealing around a window, or working on your car, this sealant provides reliable performance. It's also safe for use around sensors and is resistant to mold and mildew, which adds to its versatility. 👌 I highly recommend this product to anyone in need of a versatile, durable sealant. It’s especially useful for DIY projects, household repairs, or automotive fixes. 🏡

We recently purchased a new car. It is parked in the garage every night. The other day I noticed that a plastic trim panel on the passenger door had some scratches on it. Time to investigate! Mounted on the wall next to the door there’s a 2 inch pipe with a clamp fitting that has a protruding piece with a rough edge. This was scratching the trim when the door was opened. I took the JBweld silicone sealant and built a bumper over the rough metal. Took 3 coats to get what I wanted, but it works perfectly. This stuff is easy to use, durable and well worth the price.

Overall the product is great. The Good: It IS SAFE for aquarium usage for those wondering, and set timing is fairly accurate The Bad: This product SMELLS, it has a very very strong chemical smell ( Yes I know it is silicone and doesn't smell like roses) The Sticky: The Silicone is very sticky too be expected but the real sticky part is the fact that the tube that the silicone comes in is a metal material and as soon as you roll it or squeeze too hard the tube splits and silicone will go all over your hands, so I would wear gloves. So I will recommend this product as far as aquarium usage goes, the material of the tube is really what took the star away simply for the fact that I lost a decent amount of the product on my hands and gloves.

Works as expected.

Exelente

I went to go use it and it exploded out of the back end..I didn’t even apply that much pressure either. I was disappointed but then they gave me a replacement for it so changed the review to five stars. Thanks!

Not the most easy to use or get out of the tube... did its job though!

This product is a great product for sealing leaks, bonding materials, or weatherproofing. I used it on a cracked window frame, and it held up perfectly against rain and wind. The clarity is excellent, and it doesn’t shrink after drying. Works on glass, metal, and plastic very handy to have around

As a silicone sealant it does an adequate job, and the tube style makes convenient for home repair use. I was able to patch up a small pipe leak with it, among some other repairs. It isn't particularly easy to spread smoothly, however, and tends to clump up. Curing time is reasonable. The included application spout is not very useful. It takes a bit of effort to get it working, and then it ends up full of solid silicone that needs to be removed before it can be used again. Very inconvenient and wasteful of product. The stuff has has a very strong acrid, vinegary smell to it, until it cures. You should probably be careful to keep adequate ventilation when using it. Wear disposable gloves, too, if you can, although that can make application even more awkward. I didn't notice when I ordered it that it had to come all the way from the UK, so delivery time was long. I would probably have searched harder for a more local choice if I had.

At first i used it with the nozzle but its hard to squish it out so I had to cut it from the second circle to make the hole bigger which worked, please do not force it through the smallest hole since Ive seen some comments complaining that it bursted open and made a mess. I would recommend you remove the nozzle when you are almost done and clean it properly by passing tissue through it, using some of that product leftover. While this might be messy and a bit wasteful it will prevent both the tube and the nozzle from drying up since the nozzle doesnt have a seal. Now i use it without without nozzle and it still works nice for areas that dont require precise application or tight areas and its an amazing adhesive, it says it dries in 1h but id recommend leaving it at least half a day, do the work at night and leave it overnight maybe. Ive used it to glue some shelfs in the kitchen and put spices and sauces which can be quite heavy, left milk and other heavy items to test the durability and its been 3 weeks holding all that weight, also used the glue to seal corners in the bathroom and its completely waterproof once dry. The next time u open the tube there will be a dried up crust on the top, if u squeeze a bit it should come out, i didnt throw it away and actually placed it back once im done using the product and this actually works as a second seal that prevents another dry crust. Overall amazing product.

Quality products

The product arrived as expected and on time. I used this glue to stick a drift wood with a stone for my aquarium decoration. So far, it is holding it well and it is not causing any trouble in my aquarium. Good product.
