I used it to repair external copper piping line that had split in the winter. Worked well but I needed a couple of coats to make to fill the holes completely.
After installing roof anchors for fall protection, needed while installing hurricane-protective home window covers, I used Flexseal to re-seal the roof at the roof anchors. The Flexseal was also effective at hiding the brightly-colored roof anchors, coating them the same color as the adjacent roof shingles, which are charcoal/black in color. The initial liquid consistency of the Flexseal seeps into and around the screw-down holdings of the anchors, then dries to provide an excellent seal to the roof around the roof anchors.
It works just the way it describes it does. What else can I say?
It's been effective in sealing some small cracks in my concrete basement interior walls. It DOES take several applications, though. I ordered two more cans.
Needed something to seal the gap between the concrete front porch and the siding. Forget about finding someone to come and fix it. I bought the flex seal and did it myself.
Love the product but received 2 defective cans. The nozzle tip malfunctioned and I am left with 2 cans with more than the half the product still in it. Bummed.
Whn I ordered Flex Seal I had high hopes to fix a leak in my swim spa. I emptied the water out, cleaned the area and applied the Flex Seal tape over the crack with 2 1/2" edges refilled the swim spa and STILL had the leak. purchased the spray Flex Seal, emptied the swim spa cleaned area well, sprayed 3 coats of the Flex Seal spray to the leaking area (on top and underneath). Filled the swim spa back up and it was as if I had not done anything. As far as being water proof this product is not. The tape is very difficult to use, hard time getting the clear plastic cover off the tape.
The product worked as advertised. My problem was the length of time it took to get here . Times kept changing, delays etc .
I received old product that seemed to be laying around in a warehouse somewhere. I ordered several colors and all of the colors were old. Some had damaged lids. I was very unhappy with my purchase. The colors did not seem vibrant when I attempted to use them. I shook the cans for about 15 minutes at some point and still had the same result. Very disappointed.
I purchased this because I had a plastic pet drinking fountain that had a mystery leak that was increasing. Besides inspecting it myself, I enlisted the help of 3 friends. Not one of us could locate the leak, though it was clearly evident it was leaking! I thought well, I guess I will try FlexSeal and just spray the entire bottom of the fountain and hope it holds...Best. Decision. Ever. It is still holding fast to this day - Thanks!
