## Description

JENOLITE Stop Leak Sealer Spray | WHITE | 400ml | Leak Sealer for Gutters and Flat Roofs | Waterproof Gutter Sealant | Fills, Seals & Stops Leaks | Long Lasting Waterproof Sealant : desertcart.co.uk: Business, Industry & Science

Review: Really works - This stuff really does do what it says on the can. Like anything from this manufacturer, it’s high quality, dries fairly fast if applied in small quantities. Provided the area is cleaned reasonably well it seals without that awful stickiness of mastic. One tin will seal multiple small leaks. A note of caution, this is a temporary fix and would not be strong enough for any pressurised system for any extended period of time, if at all. Its function is mostly to stop that annoying dripping gutter, or a small crack in a flat roof. It will stop a leaking pipe at a poorly fitted union provided the thread isn’t too badly cracked and the leak isn’t huge or the pressure isn’t too high. It’s superb for its primary function and I’d recommend keeping a tin in the garage.
Review: Good for small jobs - This product is only ever going to seal the smallest of leaks or cracks, being in liquid form as it comes out of the can, drying to a plasticky finish. But in these cases it seems to be quite effective, if layered as suggested. You need to spray thinly, leave for 15 minutes and then do several times more to build an effective covering. If you're using inside I'd advice the use of a face mask. It has a strong aroma and being an aerosol does fill the air, which is not only bad for the lungs but has a strong pear drop aroma. But overall, if your gap fills the criteria it works well, though I have no idea how long it will last.
