Flex Glue, Super Strong, Rubberized Waterproof Adhesive, Works Underwater, Use on Pools, Showers, Outdoors, Concrete, Brick, Pavers, UV Resistant, 9 oz Cartridge, Clear, 1-Pack

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.

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!!

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.

Worked as advertised I have received flex glue that was unusable as it was hardened. This was good to go! Fresh and soft and sticky and waterproof. It only lasts a couple years in the sun But I just do it over every few years. Pretty good if you need it to stick in not perfectly dry or clean conditions. Pretty much worked for me. I use it to keep water out of seams or joints etc

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.

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 want Goes 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.

This product actually does work quite well. TV ads show a man squirting the white liquid adhesive between his shoe & his shoes sole, pressing the 2 together & then walking away. For my tennis shoes I had to do this: Squirt the adhesive glue in place, apply pressure to the area being glued by "taping the shoe - binding it all the way around with masking tape in order to keep pressure on the part being glued, so it would sty together, than waiting 1 week for the glue to cure and become super stable. It worked like a charm, but its' usage is not as advertised on TV...!

I bought this to repair a waterfall; to glue some rocks so it was a one-shot deal once I got everything assembled. I don't know what the shelf life of this stuff is but what was sent would not flow out of the pump gun. After cutting the tip I used a nail to puncture the seal. It would not go through so I used a hammer to drive the nail through the seal. The glue would not flow out of the pump gun. I did finally get a small glop that I picked off with my fingers and stuck to the rock surface. Actually it was so dried up it didn't stick, not to my fingers or the rock. I was committed to the project by then and I had to cut open the side and scoop the glue out with a putty knife and applied. But it was so dried up that I have no idea if it adhered to the surface of the rocks, gravity may be holding them in place. I suspect the merchant had this on their shelf for about 20 years. I think this is a merchant issue and not a product issue, I've read to many good reviews. If you are going to buy any Flex Seal product I encourage you to go to the local hardware.
