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.
Review: 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!!
