Rated 5 out of 5 by Brilliant porridge Great product and does the job. Can be messy - a bit like stodgy porridge -.so rubber gloves and old chuck away clothes are best. It`s an outside-use item and does give off an odour, not unpleasant, but may get you high if used in an enclosed area! I used it last year for the first time for repairs on cracked and torn felt and it was a great success and saved a fortune from having a new roof. Just checked it a year later and it`s lasted fine but just giving a light coating for prevention. 28 Sep 2015
Rated 1 out of 5 by Wate of money I have applied several coats / layers of this to a garage roof. first couple of weeks are ok but eventually the crack opens up again. I had to fix the leak with silicone before buying the ISOflex liquid rubber. I suspect if the surface is covered it should be ok but crack when exposed to sun light. 14 Sep 2015
Rated 5 out of 5 by Flexacryl Cementone My flat-roof extension sprung a leak on Friday with water trickling down through the light fitting. I didn't know how bad it was and with bucket in place under the light I hoped it didn't rain too much during the night. Up on the roof on Saturday morning I found a pretty decent sized crack about 20cm long and 2cm at the widest. With more rain expected I picked up some Cementone from Screwfix and went about applying it. This stuff is great. Messy, but great. It's like liquid fibreglass that you sort of push around with the brush rather than painting it one. You don't need membrane sheets as it has fibre in the sealant; very easy to apply and I would echo the other reviews on here - be prepared to throw away the paint brush and wear gloves & old clothes or coveralls. After continuous rain overnight and throughout Sunday, the bucket is dry even though it only had less than a day to set and didn't have time to fully cure. Highly recommend. 26 Jul 2015
Rated 5 out of 5 by Great for small repairs If your entire roof is leaking then you need a new roof! However if you have small annoying leaks this stuff will go along way to helping sort them out. I applied some a year ago to area that appeared to be letting water in and guess what? no more leaks! 3 Jun 2015
