Been used on multiple projects and meets all needs, amazing waterproofing

Excellent product , globular like a fibrous polyfilla.Used it over gorilla gutter tape , as an extra protective layer to keep the water out after an internal leak in a conservatory. Use gloves, old stiff paint brush , have rags and don’t touch anything other than what you want to cover.I think this will do the job on the gutter crack till I can get someone out to replace the gutter.

nothing to dislike really, this item was used for garage floor

I’ve just used this stuff to tackle several leaks in my ‘lean to’ tool shed roof. Previously I’d used a hybrid sealant with variable success but this stuff has been miles better.It is a cellulose based sealant with a strong acetone smell similar to car paint but this means it cures fast. It’s very thick and contains fibres which give it structure and strength. As others have said it doesn’t brush easily but this can be overcome by warming the tin in hot water or on a radiator for a while before use. I also trimmed down the brush I was using so that it was stiffer. Having done this it went on ok and achieved its purpose. Afterwards cellulose thinners cleans up the brush with relative ease.The tins aren’t very big so be warned but it’s meant to tackle small areas not whole roofs etc.My only slight gripe is the price, but if it works I suppose that’s what’s important.

Seems to work well but follow the instructions on the tin and ware old clothes and gloves

I have used this twice, once on a roof and secondly on a tank for sealing outside. On both occasions it has worked and more importantly lasted. Make sure you have some gloves and a cheap brush...other than that as long as you are methodical, the job will be spot on. Do not be put off, the product is easy to use, just do not get it on anything else, it sticks like nothing else I have used. Super flexible, easy to apply and the job lasts. Great for sealing roofing felt etc etc.

Amazing roof leak sealer works every time. Just make sure that you fully mix before use. Have used this on many repairs and worked every time.

Hard to apply out of tin .then did not fix the leak
