Flex Tape , 4 in x 5 ft, Gray, Original Thick Flexible Rubberized Waterproof Tape – Seal and Patch Leaks, Works Underwater, Indoor Outdoor Projects – Home RV Roof Plumbing and Pool Repairs

My from patio plexiglass that is above my grill cracked. The crack turned into a hole because of the sun and humidity and expanded. This tape adhered to the plastic and I live in FLorida where we are having tropical storms everyday and I havent had any leaks since it was applied 2 weeks ago. Great product.

This product was recommended to me when I was looking for a vinyl repair kit for my above ground pool. I placed a large piece on each side of the hole and it did not do the trick. I took it off and tried again with new tape and it still didn’t work. The wet piece I removed didn’t feel nearly as sticky after getting wet. Not the right stuff for my job. The shipping was lightning fast and arrived overnight! Great shipping but expensive and didn’t work.

Meh. It’s kind of hard to work with and didn’t live up to expectations. The glue is very tacky, which I was initially pleased with, since I planned to use this to seal a crack in the pipe that runs to our garden spigot until my landlord could get a plumber out to fix this (the garden spigot isn’t exactly a priority for him, so this wasn’t going to be done soon). This stuff didn’t work at all the first time, which I thought was just an application issue on my part, so I tried again… then again… Then I went to the hardware store like I should have the first time.For the first attempt, I cleaned the pipe thoroughly and it was completely dry. I cut off enough to wrap around the pipe, covering the small <1/4" split with the entire width of the tape and wrapped about 3" of tape around the pipe to securely hold it. I wrapped it tightly and smoothed out any air bubbles as I went to ensure the tape was making good contact on the pipe for it's full length. The moment the water turned on, it started spraying out of the ends where the tape met the starting point.I tried doing it a second time, this time drying the pipe again, new piece of tape about the same length, but this time I used a screw driver to use as a kind of bone tool to press the tape together at that first seam, thinking the tacky glue just needed to make contact and seal the little spot where the tape met itself. I also smoothed out air bubbles as I wrapped it. Still no luck.Third time, I took off the tape from before, cut only enough to warp around the pipe, so the ends didn't touch each other. Oddly enough, this worked... for a couple of hours of use. I had been turning the water valve on/off as I needed the hose, so the tape wasn't under constant pressure, thinking I could prolong it's use, but it lasted about 3 hours before a water bubble formed under the tape. Just like a balloon, once it started inflating, it continued until the bubble reached the edge of the tape and it was done for.If you need this for plumbing, I'd recommend against it. Just go to the hardware store and buy a pipe repair clamp and be done with it. The repair clamp was about $11 and has been holding like a CHAMP for 2 weeks now, this was $13 and seems like it doesn't meet even their own claims.Also note the description says the bond is permanent after 24 hours and cannot be removed... That's not true. It's as easy to remove after 2 days as it was after 2 hours.And if you have trouble getting the adhesive off of your scissors or knife, just use Goo Gone and it'll come right off. The adhesive oddly enough sticks to EVERYTHING you don't want it to stick to and scissors WILL get gunky after the first cut. Goo Gone will save your tools from this mistake of a purchase.
