No Nonsense Roof & Gutter Sealant Black 310ml is rated 4.6 out of 5 by 101.
Rated 4 out of 5 by from Sticky and messy. Wear gloves A lot easier and stickier than silicone and didn't stop the leak on my first go. A bit better result 2nd time but I'm watching with interest as I don't want to replace the guttering. Not the best product that I've had from screwfix.

Rated 5 out of 5 by from Superb ! Ok it's messy (white spirit gets it off things) but it seals roofs, gutters etc superbly. Can even be applied when the felt is wet for emergencies, just 'stir and smear' it until it sticks. For a less messy repair eg where someone may come into contact occasionally such as a shed roof edge 'dust' it with fine sand,dust or similar as it does not skin over for days and does not fully set for a long time. Does it last - oh yes really well, years even in sunny positions.

Rated 5 out of 5 by from Brilliant stuff I find this to be an excellent product which is easy to work with and reasonably priced. For a really neat job I paint it into the surface with an old paint brush dipped in white spirit.

Rated 5 out of 5 by from Works fine. It's been only couple of days since, I've applied this on my shed roof as I have discovered couple of cracks and roof started to leak. It's been raining over night and when I checked the shed there is no wet marks so far. Hopefully this temporary fix using this sealant will work on a bit longer term. It's definitely a great value and easy to use product.

Rated 5 out of 5 by from Easy to apply This item does not go off like silicones so do not expect it to. This is a high grade item not to be used anywhere else other than it's intended use. Excellent product for sealing roofs and if untidy then easy to adjust without it setting too quick. Highly flexible if you expect alot of movement then this is the product you will need. Cheap as well.....
