It works, but follow safety instructions carefully

[This review was collected as part of a promotion.] I used this to seal up a window in my basement that was both leaky and drafty. You need full body protection to work with this chemical- mask, eye protection, gloves, probably can’t hurt to use a disposable gown or jumpsuit. After you’re properly protected, you must also make sure that the area is well ventilated. Since I planned to seal the window frame, I had to open other windows. I didn’t realize it would be so strong smelling, or last so long. I had to leave my windows open for 2 days in cold/wet weather. I should’ve done more research. After it cured, the window stopped leaking and I no longer feel a draft. It was easy to paint to match the rest of the window pane. It does work, but you have to take precautions to use it safely.
I would recommend this to a friend!

Perfect

[This review was collected as part of a promotion.] I was sceptical about trying this product as it seemed too good to be true. However, I used it on a leak and it seems to have fixed it. I know it is just a temporary fix but it seems to be holding great now. Just make sure the area is dry where you use it.

[This review was collected as part of a promotion.] Love the flex seal black! this stuff works like a charm, I have a leaky gutter right on the corner of my front porch. its get colder and when it leaks it turns the front wall into ice. I got the flex seal black and as the gutter was dripping away I sprayed the area generously with the flex seal, even wet it sealed it right up, jo more leak! I truly am a fan of this product!

Good for the right applications

[This review was collected as part of a promotion.] I must say I was a bit hesitant about the claims of this stuff. This stuff is pretty good though. Make sure you fully understand what this stuff is, how it is supposed to be used (safety especially), and have a realistic expectation of what it can "fix". I was able to use this to seal a cracked pot with a plant in it. It worked fine for that but I would not expect it to work on anything that is under "pressure". I've not tried their seal tape but would like to.

[This review was collected as part of a promotion.] I used it on the interior of my gutters at all the joints. it worked great! but when i used it on the exterior of a shed where i had water running directly into the base and it would leak into the shed. i applied it to the bottom of the shed hoping the flex seal would divert the water. but it did not work the water seeped through the bottom.

Easy to use, good for sealing home leaks

[This review was collected as part of a promotion.] This Flex Seal is easy to use around the home. It is useful for sealing leaks or cracks and seems to work well to stop leaks and prevent future leaks. It comes in an easy to dispense can. Be warned it does have a dangerous chemical warning.

[This review was collected as part of a promotion.] A good invention. I have used some of the can. It sprays well and coats evenly. Is an easy thing to use as a waterproofing fix Be sure to follow all instructions and ventilate room as much as possible.

Great product, but can make a mess in humid areas

[This review was collected as part of a promotion.] It took me a while to get the hang of using Flex Seal in the spray can. The directions on the can are really good and do a good job explaining how to apply it, even for someone like me who does not do well with DIY type stuff.
I first used it to repair a leaky gutter. I ran into problems with this project because the gutter is always wet. I knew the product needed to be dry for 24-48 hours for it to be effective, but this seemed impossible due to an all metal roof and high humidity. I rigged up a high powered fan to point at the leaky spot and this seemed to work. It has not rained yet so I am not sure how well it sealed the leak.

It did work wonderfully for repairing some cracks in some flashing on my roof. The cracks were not causing leaks in doors, but the area covering my porch was leaking and now it appears fixed. I used to see sun through those cracks and now I cannot. It took several layers to get them sealed.
