Works underwater - my main issue
I have a pool lined with one inch square ceramic tiles that line it on all sides and the bottom. Over time some tiles on the side thats gets the most sun fall off due to vacuuming, settling or possibly really hot sun on the tiles and then cold that makes the tiles expand. Be that as it may, I've used at least a half dozen products to re glue the tiles. Few work well, if at all, none underwater and few can take the effects of the elements. I bought Flex Flue (the 6 fl. oz tube) as a last resort and have used it on the sides of the pool as well as underwater (obviously this is tricky to apply and you probably need somebody to hold you down!). It's been nearly 5 months and none of the re glued tiles in or out of the water have fallen off. Ive vacuumed (inadvertently) over the ones at the bottom of the pool and they've stayed in place. The product works as advertised and is reasonably easy to apply, though it dries fast and you'd be advised to have the job set up before opening the tube. It is also progressively harder to use as the product becomes harder in the tube so if you have several spaced out jobs you may want to consider getting several tubes, even at the expense of throwing out those half empty. In conclusion, it's the only product i found that gets a water job done.

Good Product worked well
Few pointers- You need a caulk gun- You need to cut the top instead of poking a hole after you unscrew the top dispenser plastic- You need to cut the top dispenser plastic to the desired size to match the stream you wantGoes on very well - used it to seal around the shower pan. Used a box cutter to snip off the plastic and the top, unless you do this the product will not flow properly and you will need a lot of pressure to get results.Let it dry for 2 to 7 days depending on your application. For me 3 days were enough, even after 24 hours the product was firm to the touch. The product dries but does not completely harden which does not appear to impact the adhesion.Would buy again.

Great for pool repair
Works as advertised. I use this to repair tiles on my swimming pool that need to be reattached. Works well on dry and wet surfaces.

RATHER DISAPPOINTING I'M SORRY TO SAY
I've purchased this item twice. The first tube arrived broken, leaking and had dried up. Amazon was true to their policy and quickly replaced it. I was happy.A few weeks after receiving the 2nd tube, I glued a wrist rest to my keyboard support. Note: I use an articulating keyboard which extends out from under the desktop. The wrist rest needed to be glued down so it wouldn't constantly fall off.The tube says "super thick formula" and it is. So I squeezed out a generous amount, set the wrist rest on top and pressed it down - it stuck firmly right away and seemed dry enough to use the next morning. I thought "Great!"But a month or so later the wrist rest just popped right off. The glue was dry (of course) and very yellowed, I have no idea why. So I got out the tube, opened it up, discovered it was thicker and stiffer than the first time and very difficult to squeeze out. After the first use, I had carefully followed the directions for sealing it back up, i.e., squeezing out a bead of glue to form a seal, then replacing the cap. There were no leaks, so I don't know why it seemed drier.The tube label says (among other things) that it's "Excellent for: Home & Garden, Automotive & Marine, Plumbing & Electrical, DIY Projects & Hobbies, and so Much More!"The bottom line? I've used other Flex Seal products and been quite satisfied because they worked as promised. This one however, I'm disappointed. But I've glued the wrist rest back on and I'll see how it goes.

FLEX Glue is AWESOME!!!
This is the best glue I ever used. I used it to hang shelves and the shelves support a fair amount of weight. I've used it to seal the shelf holders onto the side of my old fridge. There's nothing you can't glue with Flex Seal Glue!! Two Thumbs up and 10 stars!!

Flex Seal
The product definitely did what it was suppose to. I wanted to repair a pair of golf shoes where the soles separated from the shoe. I have tried other products to repair them to no avail. This glue worked like magic. I was a little disappointed because this tube of adhesive is different from the others. I did not realize that you must remove the dispenser prior to use and cut the end of the tube. When I tried to use the product, the glue started to come out of the seams of the tube therefore I wasted some of it. I think the company should warn the consumer that you must cut the cap at the end of the tube for it to work properly. My fault for not reading the instructions but I assumed it worked like the other manufacturers with similar products. Ease of use not the best but the product performed beautifully.

なぜ、日本にこの商品がないのか・・・良い商品です
なぜ、日本にこの商品がないのか・・・良い商品です耐久性や質感も良いです。粘度が高いので伸びにくいですがしっかり防水されています劣化が国産に比べて長く、良い商品だと思います。
