Rated 5 out of 5 by from Just "Gloopy" enough.... Used this to seal around flat roof skylight where there was a tiny unknown, where from leak when it rained. Manageable and just right consistency to ladel on and still spread a bit if needed. You can't tell difference on felt seams between this and bitumen so looks professional but even better, it works... Use old brush, dollop on don't try and paint it on... then spread gently but leave about 3mm thick, did seam all around 1m x1m sq skylight and had loads left... the garage roof next..... Also cheapest about, checked all norm trade places..

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.

Reinforcement MEsh

I need to repair a felt roof, can this product be used in conjunction with a reinforcing mesh?
Asked by: Anonymous
The Cementone Roof Repair Compound Black is a solvent based fibre reinforced acrylic roof coating designed for application to roofs such as asphalt, roof felt, concrete and wood among others. When applying the product, it is relatively thick and so it will fill any fine cracks in the substrate. For larger cracks, a scrim can be used such as fleece ( that is normally used for protecting plants in frost ), cut this into suitable strips and apply into wet repair compound over a crack before applying some more compound over the top. Outside of this the product is not designed to be used in conjunction with reinforcing mesh as such.

Can Roof repair be over painted

Can this product be over painted with reflective Aluminium roof paint.
Asked by: Tractor37142
The Cementone Roof Repair Compound Black is a solvent based fibre reinforced acrylic waterproof roof coating designed for application to roof surfaces such as bitumen, asphalt. concrete and wood among others. Once applied the product will be the final finish and so it is not suitable to have an aluminium roof paint applied, however it does have better UV resistance than a bitumen based product.

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.
