Rated 5 out of 5 by Fixed leaky roof from inside! I used this stuff in my loft where a tear in the roofing felt was allowing water through from a gully on the roof. The surface was was wet when I applied this stuff but it adhered perfectly with no issue. It is very messy to apply (wear gloves!), make sure you have something disposable underneath where you are painting as this stuff goes everywhere. I applied it with a cheap, disposable brush which helped to get it into all the cracks and gaps. It constantly falls off in bits as you apply it (if you're doing it from underneath as I was) but just keep slapping it on until the whole area is covered. I've had 2 lots of rain now and my leak is completely fixed. Still going to do a 2nd coat in a few days just to be sure. Recommend this stuff! 14 Jun 2016
Rated 4 out of 5 by Shed roof repair I bought this to repair a shed roof as the roofing felt had split in a few places. I bought it on a hot day so it was easy to apply. It was a gloopy consistency and I found it was easier to scoop it out and then brush it in. Using the brush did not pick up enough. Went on well, will have to see how it performs when it rains. Use a cheap brush and expect to dispose of it and make sure you wear golves/overalls. 8 Jun 2016
Rated 5 out of 5 by Garden post waterproofer I used this in the grey colour to cover the bottom couple of feet of pointed garden posts 2 years ago. I have just recently taken the posts out to re-use elsewhere and they are perfectly intact and there is no rot on 12 posts. It works on roofs as well! 5 Jun 2016
Rated 4 out of 5 by It stopped a leaky roof used this on a felt shed roof that had 2 huge leaks been 2 weeks now and no leaks so hopefully will last a good while, not the cheapest but if it lasts will be worth it. 6 May 2016

Answer: 
The Cementone Roof Repair Compound Grey 1 Kg is a fibre reinforced acrylic waterproof roofing product that is designed for application to various roof surfaces including bitumen, asphalt, roof felt, concrete and asbestos cement. The product needs to be applied at a rate of 1 to 2 kg per m², the coverage for the product can vary depending on how rough or smooth the surface is that it is applied to. Also, consideration will need to be given that with corrugation, the actual surface area to be covered will be greater than for the same area for a flat roof. In general, only one coat is required.

Answer: 
Thank you for your recent enquiry relating to our product.
Unfortunately I have to advise that none of our roof waterproofing products including our Roof Repair Compound are suitable for fibreglass surfaces. As Fibreglass is already a waterproof surface the roof repair compound is unable to 'wet out' on the surface.
Please accept my apologies that I am unable to offer you a product from our range on this occasion.

Answer: 
Thank you for your recent enquiry relating to our product.
I can confirm that our Roof Repair Compound will seal lead flashing. You just need to ensure the surface is clean and sound before application. If the surface is particularly difficult then you may need to consider the use of a penetration primer.
I hope this helps.

Answer: 
The Cementone Roof Repair Compound Grey is a fibre reinforced acrylic waterproof coating designed for exterior only application to roof surfaces such as roof felt, asphalt, concrete, wood, slates and roof tiles. In general one coat is required and needs to be applied at a rate of 1 to 2 kg per m², the coverage will vary depending on the texture of the surface so for a smooth surface you will get a better coverage rate for a rougher surface you will get less.

Answers

Answer: 
The Cementone Roof Repair Compound Grey product ( Flexacryl ) is a fibre reinforced acrylic waterproof coating designed for application to roofs typically constructed of roof felt, asphalt. concrete or wood. In general the product cannot be applied to a previously applied sealant unless it was a bitumen based sealant. This will include sealants such as silicones and MS Polymers where you will get a chemical reaction that liquefies the products after a short while.
