Rated 5 out of 5 by from DIY Excellent buy does what is says on the tin. Used to fix garage roof the cement and tile had cracked causing damp in a corner. Applied one coat and so far no problems all seems well. will give it a second application to be extra sure not that it seems to need it. Much cheaper than getting a roofer in to quote a big bill.

Rated 5 out of 5 by from Good stuff I bought this to tackle a substantial leak in our flat roofed porch. Although I removed most of the pooled water from the roof, it was still very wet, but that wasn't an issue as this stuff went on no problem - even through what water was still there. Dried fairly quickly and just in time for a downpour following which the water pooled again on the roof but without any hint of a leak. Result. I'd definitely recommend this stuff however I'd also advise wearing gloves and anything else you'd happily throw away afterwards.

Shed Roof

Can this be applied to a pent roof with standard roof felt bitchumen - to repair a few cracks. ta.
Asked by: SteveoK
The Cementone Roof Repair Compound Black 1 Kg is a solvent based acrylic coating designed for application to roofing such as asphalt, roof felt, concrete, wood and metal. The product can be applied over cracks in roof felt as long as the roof felt is basically sound and the cracks are hairline or small as the product is fibre reinforced. However, for larger cracks a scrim can be used such as garden fleece ( a lightweight cloth material normally used for protecting plants from frost ) or hessian cut into strips and placed over the crack having first applied a layer of the compound immediately before, then immediately after, apply another coat over the top.

Asked by: Boyo69
The Cementone Roof Repair Compound Black 1 kg is a solvent based fibre reinforced acrylic waterproof coating designed for application to roofing materials such as bitumen, asphalt, roof felt and concrete among others to provide a waterproof seal and extend the life of roofs on buildings. As such the product is not suitable for application to a previously painted surface or indeed for motor vehicle roofs or panels.

what is the coverage of a 1kg tin ?

Asked by: ardd
Thank you for your recent enquiry relating to our product. I can confirm that a 1kg tin will cover approximately 1m² depending on the surface it is being applied to. The smoother the surface the higher the coverage rate. I trust this helps.

Can this paint be painted on the inside of a shed with a felt roof it is wooden inside

We cant locate the leak from the outside of the felt roof but we can from the inside however this is wooden we are just wondering could we paint it from the inside many thanks
Asked by: 1975ali
The Cementone Flexacryl product is a solvent based acrylic waterproof coating designed for exterior application to various surfaces including asphalt, roof felt, concrete and wood. However it is not designed to be applied internally due to the solvent nature of the product or indeed for overhead applications where it will be difficult to apply and also the product will have difficulty achieving a successful bond. As well as this, when in service, it remains soft underneath but dries hard on top providing a waterproof seal but the product is not designed to have the underside of the application as the waterproof seal and so it would consequently fail.

Will the product adhere to Polypropylene.

I have a polypropylene waterproof membrane on my roof and it is perforated in places. I would like to coat the whole surface with a sealant.
Asked by: Anonymous
Thank you for your recent enquiry relating to our product. Unfortunately I have to advise that none of our roof waterproofing products including the Cementone Roof Repair Compound will bond to a polypropylene surface. Please accept my apologies that I am unable to recommend a Bostik product on this occasion.
