Review: It does the job correctly, just prep and works - The JENOLITE Stop Leak Sealer Spray is a great solution if you have irritating leaks in your gutters, roofs or other surfaces. Honestly, I was sceptical. We have had a 15mm Perspex joined roof leaky on and off for the last two years and I just did not want to replace it with so much other DIY going on. All my other fixes, tape, sealant, more edging, larger flashing, worked for a while, but started leaking again within three to four months. Then I used this spray over a year ago and it has not leaked since. I was so impressed that I even bought some to help my mother-in-law with a similar issue. You MUST properly prepare the area—I mean really prepare it. I learnt this the hard way. The first time, I just wiped it down and sprayed it and within four weeks, it started peeling and looked like fish scales! If you take an extra 20 minutes to ensure that the surface is clean and completely free of oil and dirt, this stuff works. The spray dries quickly. Just shake it up and apply in small, thin layers; do not try to empty the can in five minutes. Let each coat dry properly. Unlike some other sealers, it creates a semi-flexible, watertight seal that will not crack over time. However, I am not sure how well it would perform in areas with a higher movement. I have used this on metal, concrete and plastic. A week after application, we had significant rain—no leaks, no peeling… nothing. It is also UV-resistant, so I am not worried about it breaking down in the sun. When I inspected the area about 12 months later, while doing other work, it was still in good shape. I suspect this is because the spray seeps deeper into the gaps compared to tape and general sealant. This is a solid leak fix. I originally thought it would be just a small-scale temporary solution, but it has lasted more than 12 months and gave me time to focus on other house projects. It saves money on repairs, is durable and is easy to use. If you have leaks, grab a can and try it; you might save yourself hours of frustration!
