Reliable and handy

Does well!

[This review was collected as part of a promotion.] This epoxy does what it’s supposed to do, and it does it well. The consistency is thick but still easy enough to work with, and once it sets, it really holds strong. I used it on a small repair in the garage and it bonded nicely without any mess or sagging. The black finish blends in better than I expected, which is a bonus if you’re using it somewhere visible. You do need to work fairly quickly once it’s mixed because it starts curing pretty f...

It works!

[This review was collected as part of a promotion.] I put this product to the test! We have a 100-gallon fiberglass water tank that had a leak. We looked at patch and repair kits but thought for ease and cost, this might work. And indeed it sealed the crack and stopped the leak. It has been a week and no issues. I was pleasantly surprised how easy and effective this was! Highly recommend.

This stuff sticks! 🤣

[This review was collected as part of a promotion.] I had a cap on one of my bats come off during a game. I tried a few other epoxy’s that didn’t last very long. After using this Flex Seal Epoxy, I have swung this bat over 100 swings and it is still holding strong! Highly recommended!

Good product.

[This review was collected as part of a promotion.] This stuff has provided a 'final solution' for certain outside wood on my home. Good product, pours smooth,seals great. I hope it last longer than other things I have tried.

Works but keep the package you need it.

[This review was collected as part of a promotion.] Step 1 be sure to not discard the packaging! The kit includes a double syringe a mini wood craft stick and it says plastic tray but it’s actually the the package. The plus side the syringe does come with a resealable twist top so you can use more than once. The downside you can’t just squeeze this into a crack it has to be put in place using either the craft stick provided or something else. To use it you must squirt it into the plastic packag...

Awesome!

[This review was collected as part of a promotion.] Pretty neat! I fixed several things around the house and the barn with cracks and it holds up great. Now I don’t need to buy new things all the time.

Came just in time!!

[This review was collected as part of a promotion.] I received this complimentary product in exchange for honest review. I had just nearly lost the sole covering of one of my favorite pair of shoes and this showed up just in time. Holds tight! The black blends in with the shoe. It is a little messy though. It’s not coming off of anything else it gets on so be careful!

Husband loves it

[This review was collected as part of a promotion.] Well my husband stole this so I guess it's awesome😂 He was like, "oh thanks I've been seeing to try this- yoink" But apparently he used it to repair all kinds of things that he is very excited about and he dared me to figure out what things that had broken are now fixed, and I can't tell. So this stuff clearly works fantastic.

Not just any glue, it's as strong as my DIY

[This review was collected as part of a promotion.] If you have DIY projects in mind but need something steady and durable - so.ething you can truly rely on - then this epoxy bond is for you. It is so diverse and valuable that you can use it on a variety of materials, from metal to tile to wood to brick. I used it on a cute birdhouse that had been on my mind for a while. There are bluebirds and cardinals that visit my front porch now. They don't mind the smell, and neither do I. It's packaged so...

Quality

Seals everything!

[This review was collected as part of a promotion.] This is a versatile product which can be used in multiple areas and different type of materials as well. Once the liquid is applied it dries sooner than other similar type of liquids and helps gets good coverage and is highly durable not to mention the odor is not unbearable.
