Review: Strong grip and easy to use - Wow. Just wow. I used this stuff to glue a handle back on to my fireplace door after replacing the glass panel that had shattered. The handle only has two small posts that connect it to the metal door frame, and I was uncertain whether there was enough surface area for the glue to hold. After applying the glue to the handle I let it set up for 24 hours, and MIRACLE - it is holding strong and tight! This stuff works. A great product that solved a difficult problem, I am very happy that I bought this.
Review: J-B Weld High Heat Syringe, Dark Grey - This stuff is awesome. I recently discovered J-B Weld. I'm a 60 ish year old woman who knows just enough to be dangerous when it comes to diy repairs. I used it to seal a crack in my concrete furnace pad. I taped off the concrete surrounding the crack and used a throw away sponge brush to fill the crack and smooth out. I then removed the tape and it looks like a professional job. Was quite pleased. Wish I would have known about this product sooner. Also, mixing the product is extremely easy with the provided plungers that squirt the exact amounts of liquids simultaneously.

### ⭐⭐⭐⭐⭐ Easy Fix for Cracked Chimineas (and More!)
*by F***A on May 9, 2024*

I'm really impressed with the J-B Weld High Heat Epoxy Syringe. Fixing cracks can be a hassle, especially when you need something to hold up to high heat. This epoxy syringe made the whole process so much easier. The One-Step Syringe is a Game Changer - Forget messy mixing and imprecise measuring! The one-step syringe design is genius. Just dispense equal parts of the epoxy from the dual plungers and you're good to go. No mess, no fuss, and no chance of messing up the ratio. The epoxy sets up in about an hour at room temperature, and cures completely in 24 hours. That's plenty fast for most repairs. But the real winner here is the heat resistance. I used it to fix a crack in my chiminea, and it's held up perfectly through the first few fires. I'll definitely update this review after I've used the chiminea for a longer period, but so far, I'm very happy with the J-B Weld High Heat Epoxy Syringe. It's easy to use, bonds like crazy, and can take the heat. Highly recommend!
