Rated 4 out of 5 by Time will tell Have now applied the stuff, and time will tell whether it does the job, which is the only reason why I've not given 5 stars. Well worth trying it out for the price though. 18 Apr 2016
Rated 5 out of 5 by Just the job Bought this product to fix a whole bunch of leaks in my garage (asbestos) roof, I've got to say it was wonderful for sealing all the joints and old screw heads, the fibres really give it some strength and thickness its was water tight by the next day. Just make sure you've got a nice cheap pair of disposable Gloves to throw away after your done, and same to be said with a brush, if you need to do the Job over a couple of days like I did, store the brush in a plastic bag and make sure its air tight (an old painters trick) that way you can use the brush for the whole of the job. 18 Feb 2016
Rated 5 out of 5 by Roof emergency repair Used this to fill a few gaping cracks along an edge of a flat roof. To be frank this product is not easy to work with and everything which touches this stuff can be thrown away. However it fills even large gaps easily and settles quickly and nicely, once you get the hang of it. How effective it is remains to be seen as it has not rained in earnest yet... However the gaps and cracks seem completely sealed up... 7 Dec 2015
Rated 5 out of 5 by Fixed and watertight I had a couple of small leaks in my workshop roof. After having read the glowing reviews on here I decided to pop down to Screwfix and give it a try . The assistant showed me the 1kg tin on the screen.I chose the blue one labelled Cementone /Flexacryl.He bought out one by Bostik so I asked him to get the other one. I later realised this is made by Bostik so they must be the same. The roof was still a bit wet and damp so I brushed away the small stones and using a paintbrush started applying the sealant.I had an old piece of asphalt and used it like a patch .Used some small roofing nails to hold it down and sealed is all up. You can do all this in the wet and damp and it still works. Re checked today and its all watertight and saved me a lot of stress and hassle.Great product would thoroughly recommend this . 14 Nov 2015

Answer: 
The Cementone Roof Repair Compound Black 1 kg is a fibre reinforced acrylic waterproof coating that is designed for general application to roof surfaces such as bitumen, concrete, fibre cement and roofing felt among others. The product needs to be applied at a rate of 1 - 2 kg m². The actual rate for a given application will vary depending on how rough or smooth the surface is, but in general for a rougher surface you will get less coverage, for a smoother surface you will get more coverage.

Thank you for your enquiry.
Unfortunately we do not believe this product would be successful on UPVc. It would perform on well prepared aluminium.
I hope this information helps.

Answer: 
The Cementone Roof Repair Compound Black 1 Kg ( also known as Flexacryl ) can be applied to a damp surface as long as any excess wet or pooling water is brushed away first and as long as the surface is of a sound nature. However if the surface is highly porous or friable then it will need to be dry and have a thin bitumen primer applied first such as the Evo-Stik Flashband Primer 500 ml. This should be allowed to dry before applying the Flexacryl. The product is not designed to be applied to rubber roofs or fibreglass.
