Rated 5 out of 5 by Fantastic product Tried this stuff after reading other reviews, it is easy to use even for a DIY amateur. Works even in the rain, without having to prepare the surfaces too carefully. As others have said, use gloves and a cheap brush & bin it afterwards. A part-used tin kept for over a year with no apparent problems, this is a really useful product. 12 May 2016
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

Answer: 
The Cementone Roof Repair Compound Black 1 Kg is a solvent based fibre reinforced acrylic roof coating designed for application to substrates such as asphalt, roof felt, fibre cement and concrete among others. Ideally the product should be applied to a dry surface but it can also be applied to a damp or wet surface. In such a situation you will need to make sure that the substrate is of a sound nature and is clean, free of contamination, also, brush away any pooling or excess water first before application.

Answer: 
Thank you for your recent enquiry.
Unfortunately, we would not recommend the use of this product on your balcony. The Bostik Cementone roof repair compound remains soft and tacky and therefore not designed to be applied in areas that will take traffic.
I trust this helps.

Answer: 
The Cementone Roof Repair Compound Black is a fibre reinforced acrylic waterproof roof coating that can be applied to roof surfaces such as roofing felt, asphalt, concrete and fibre cement. Once applied the product goes hard on top but remains soft underneath. When in service the product is intended as the final finish and so consequently it cannot have roofing stones applied on top.

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.
