## Description

Product Description NEW! Easy Squeeze Formula (Tubes). Our legendary adhesive with instant grab and hold now dispenses easier and flows evenly for precise application with minimal effort. Pro Formula (Cartridges). Features even more instant grab and hold power for super-fast adhesion. (Caulk gun required.) Bonds almost anything. Fills gaps in uneven surfaces and adheres to both porous and non-porous substrates for a superior bond. Works on wet and dry surfaces… even underwater. Repair almost anything, anywhere. It even cures underwater. UV and chemical resistant. Won’t shrink or crack. Great for indoor and outdoor repairs that will last for years. Made in the USA. Flex Glue is proudly made in America, using globally sourced products. DIRECTIONS: (Caulk Gun Cartridge) Unscrew the nozzle and cut off tip, leaving thread intact. Insert cartridge into a standard size caulking gun and squeeze trigger. Apply to one side of the surface being bonded and apply firm pressure for 10-30 seconds for instant grab to take hold. After use, squeeze a small bead from the opening to form a plug. Simply cut the plug when you want to reuse.

Review: 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。
Review: 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.
