J-B Weld Multi-Purpose Putty - 1 Gallon - Home Exterior & Interior

It came without the hardener but I contacted jb weld and Natalie took care of it within 3 minutes and told me to expect it, and an extra tube, in the mail in a few days.From previous experience, I know this product is awesome, and almost as hard and strong as straight epoxy . And much cheaper

I used this to repair some rot in a windowsill. There are many videos out there explaining how to do this. The product is a 2 part putty that, once mixed, gives you about 5 minutes to work with. As the reaction occurs, the putty becomes thicker and thicker giving you ample time to shape it. After it sets for about an hour, you can actually shave it with a putty knife to reduce sanding later. Finally, after 24 hours, it sands like wood. Sand it, prime it, paint it. The repair is invisible. I even used it to fill minor dents in exterior steel doors. Be sure to sand it down to bare metal before applying it. Sand, prime, paint. Awesome stuff.

I needed to repair some edging of my concrete fireplace. The putty dries VERY quickly so you'll have to do in super small batches. Don't be misled by the helper video which used a LOT. It dried super solid within a couple short minutes. Once I figured out the timing, I spread it on, smoothed it out and after drying and a quick sand, the result is awesome.

Great product that sets up fast and yields a lasting tuff bond!

I used to do body work on cars and sometimes had to use Bondo to fill dents. This Wood Filler Bondo is AMAZING! I highly recommend this product for small areas of dry rot or damage to exterior wood. Make sure to remove any rotted debris, sand the area and use a liquid wood restore product, like JB Weld 40001 or the Bondo brand, prior to applying the Bondo Wood Filler. One of my favorite wood repair products so far! Saved me hundreds by allowing me to repair small areas instead of replacing wood siding.

I built a wood banister and my dog chewed through it in multiple areas. I thought I would try this so he wouldn’t be tempted to chew again because it doesn’t smell like wood and is hard as a rock. It’s working so far 🤷‍♂️. It does dry fast and is kind of difficult to mix but well worth it imo

We've used this for many projects around the house. It works great, is easy to use & to sand smooth, dries quickly, is waterproof once dry & gives a great finish. Definitely will buy again & do highly recommend it.

This stuff is amazing and just plain works. You need to work in small batches. Gets hard very quickly.
