Thicker than I expected and therefore a bit tricky to use without it looking a mess. Hopefully will do the trick of stopping the leak.

Great solution for leaky gutter. Make sure you clean surface thoroughly before use. Works well

We have had a leak in our guttering which we could not see with the naked eye. I was watching TV and saw an add for CRC leak stop. We couldnt just pop down to our local Mitre 10 as it was lockdown so we ordered it via click and collect. We followed instructions with several applications snd several weeks later no leak. Very happy customers.

Used this product on a garage gutter, the translucent seal fast became a yellow colour that looked terrible on the blue gutter. I had to use to plastic paint scraper to remove.. Do not recommend in visible places.
Bought this product about one year ago to fix leaky brick mailbox. It never worked and after 10 months or so, the membrane changed from translucent to yellowish. The failed membrane is also difficult to remove.
Attempted to use this to real a leaking aluminum ice box, but the product won't go off or dry and is super sticky and almost impossible to remove.I've even used warm and cool air fans in an attempt to get it to dry but nothing has worked - useless
I brought this product to stop the corners of our gutters on house from dripping. Just cleaned the guttering and sprayed it on. Easy to use and has sealed the corners. Fantastic.
Quick fix - easy lockdown solution to a minor garage roof leak. While initially slightly dubious, it would seem this product has done form of foaming capability that meant it readily blocked all gaps
The product seems to have worked, however it got blocked just after 4 seconds of spraying. Cleaned the nozzle and once again blocked. Haven't even used 1/4 of the can and it blocked so many times I gave up.
good stuff...sealed fly screen on padio door to stop wind coming through..Worked like a beauty and didn't have to buy a fully new door and light still gets through which is what i wanted..Winning
