I've had success with Flex Tape products in the past, but hadn't tried their glue formula until recently. What took me so long? There's so much to love. Application is easy, using a caulk applicator. I was impressed with the viscosity of this glue. It stays put, and doesn't drip or run. It helped me repair one of the original windows to my home, dating back to 1950, which had a broken glass pane. I was able to set it in place in the garage (always be aware of off-gassing in adhesive products and use in a well-ventilated area), and within a few minutes, it was firmly in place. It's recommended to work quickly, as it won't move much, if at all, 10 minutes after application. Still, I let it sit for a week to fully cure, and installed it into the home. It's ... MoreI've had success with Flex Tape products in the past, but hadn't tried their glue formula until recently. What took me so long? There's so much to love.

It's crystal-clear and doesn't impede my view. I have peace of mind knowing it will not budge in the ice-cold Upstate winters, where we get the occasional -20°F wind chill a few times a season, as it is rated for temperatures as low as -40°F. All in all, it's a phenomenal product. I'd recommend it to anyone who needs a permanent bond in their projects and doesn't want unsightly visible glue marring appearances.

I am truly impressed with the quality and strength of this flex glue. This glue is exactly as described; it is super strong and truly waterproof. With summer comes hot weather and what better than a pool to cool you off. Well our pool stairs stared to split a little at the seam so this glue came at the perfect time. We have tried many different things to try to patch them but have not had any luck. I thought what do we have to lose and gave this a try. I am so thankful I did because it sealed the cracks and left the stairs super strong, even to the stairs in the water. The glue has stayed in place and not given away. I would definitely recommend this glue to anyone who is looking for a strong and durable glue as you will not be disappointed but his one.

Just got my Flex Seal -- Flex Glue 9oz. cartridge Pro Formula Clear recently. I am reworking my bathroom and I have a couple of things that needed the flex glue. First of all, I used the flex glue for the back splashes and chair rail wood. I put a few blobs of the glue on the backside of the boards and used painters tape to hold in place. The application was smooth and easy. I waited a couple of hours and they were nicely in place. Great because I was wanting to skip the hardware into the dry wall, and just glue in place. Saved me alot of time and effort (plus easier to remove later if needed -- no patching). Excellent for the moisture of a bathroom. Also used to set/hold the walls for the shower enclosure. There are countless areas to use this product. Great for ... MoreJust got my Flex Seal -- Flex Glue 9oz. cartridge Pro Formula Clear recently.

I did a couple of tests with my Flex Glue adhesive just to see if it worked as advertised. I used the Flex Glue to glue four ornamental rocks together, pyramid style. The glue held the stones together and the adhesive remains flexible.I then glued two pieces of cedar lumber together, without clamping. 48 hours later, I cannot pull the pieces of lumber apart.Finally, I took a small plastic pail and drilled a 1/4” hole in the bottom of the bucket. I filled the bucket up with water. I took the caulking gun with the tube of Flex Glue in it and put the tube into the pail of water over top of the hole and squeezed the Flex Glue over the hole. It stopped the water from leaking out of the pail. Flex Glue really does work under water.
I flexed out my muscles, so much trying to get this glob of glue out. I've had positive experiences in the past with other Flex Glue items, but this time it was more work than it was worth. The main project that I got it for was impossible to do with it. I needed a nice flowing constancy, but it was very hard to get it out. When I originally went to use it I needed to cut off the plastic top. It was pretty thick, so I had to use a knife with a serrated edge to open it. It cut open easily enough with the right tool. I made sure that it was a nice round and well opened before putting on the screw cap that you squeezy the glue out of. The cap is nice it has some premeasured circumference areas that you could use for an ideal flow. Unfortunately that did not come in ... MoreI flexed out my muscles, so much trying to get this glob of glue out.

I did however have another very small wood project that required a little glue that I used some for. It did hold well for that repair. The glue is said to work under water, be mildew and UV resistant, paintable, solvent free, VOC compliant, and will not shrink or crack. On another note it didn't work that well for me and it can cause cancer and reproductive harm. I still like Flex Glue. I've had other positive experiences with a different sealer of theirs. Maybe I'll give this one a try again with a different tube, but so far I'm not impressed.
Love this caulk. Worried it would mold..so far so good. Used to caulk windows Just used last week. Used with caulk gun. Little difficulty getting hole to access just because I did not remember I had the access rod on caulk gun tried to punture with nail.. Easy to use. Just needed to cut end larger access for distrubution. After that, profect completed
I recently purchased the FLEX GLUE - 9 oz Cartridge Pro Formula - Clear, to use on a wood working project I had planned that would need to have a water tight seal. Before I got around to starting that project, I’d noticed that the drivers door on my truck was sagging and popping, due to a couple of stripped out bolt holes on one of the hinges. I’d seen the claims about how strong snd durable Flex Glue Clear was, and got the idea of using it to repair this, and man did it work out great. I removed the door and hinges and cleaned the surfaces, then applied the Flex Glue Clear to the back side of the affected hinge, then put the bolts back in and let it sit overnight. The next morning when I checked, it seemed to be pretty solid, so I put the door back on to see how it ... MoreI recently purchased the FLEX GLUE - 9 oz Cartridge Pro Formula - Clear, to use on a wood working project I had planned that would need to have a water tight seal.

The next morning when I checked, it seemed to be pretty solid, so I put the door back on to see how it did. To my surprise, it held great and there was no longer any sagging or play in the door whatsoever, and it looked and worked like it had just been factory installed. That was almost a month ago and even with all the opening and closing, vibration from driving the truck, and through the elements outside, it still looks and works as good as new. I’ve already purchased more Flex Glue Clear and have several projects planned for its use because this adhesive has got to be the best thing ever invented since sliced bread!
This is a good product for miscellaneous construction projects or repair jobs. I used this in a few applications and while it works very well compared to others on the market there are some that are better depending on what you are using this for. while the info commercial shows the instant gripping a brick to another brick that is not entirely accurate. They use excessive amounts and also don't hold it up for very long. The instructions clearly state you need to apply pressure for about 30 seconds. It will hold decent if you hold for 30 seconds or longer or in some cases temporary bracing. I used this to glue wood to the wall for making shelves and if you do not hold for 30 plus seconds it will sag of fall off. I also used outside to fix a veneer stone that was ... MoreThis is a good product for miscellaneous construction projects or repair jobs.

If you base it solely of the commercial it may not live up to your full expectation but it is darn close.

No need for screws or nails, it’s perfect for all types of repairs. Flex glue is super thick, it wont run or drip during application. This can also be used on dry or wet surfaces-and even underwater. Which is amazing. It is strong and has an instant grab adhesive that works like a magnet, locks into place and holds on tight. It is mold, mildew and weather resistant and remains flexible.

Flex Glue isn't just a gimmicky product that only works on the TV commercials. It works in real life! I found it easy to spread and it always dried to a clear, matte finish. I used Flex Glue to put up a small tile border around my kitchen, even behind my sink where water is constantly being splashed. Not only did it stick the tiles up quickly and permanently I was also able to use it to create the bead to seal between them and the counter. In addition to that, it is mildew resistant so I have now worries on its durability in the location I chose. I also used Flex Glue to glue colorful glass beads onto concrete stepping stones for my garden; the application possibilities are endless! I did encounter two minor issues.

Second, make sure to seal it correctly according to the instructions so it won't dry out! I highly recommend Flex Glue and am more than happy to add it to my crafting arsenal as my go to adhesive for wood, glass, tile and more!
