Rated 4 out of 5 by from Flat Rook Leak Seal Used this on a felt roof with stone chippings, which had a very minor leak. Easy to apply and sticks well to the surface, but needed two coats in places as I couldnt get all the chippings off before I started and the fibres in the mix mean that the liquid has limited workability to get into all the crevices. Waiting to see if it cures the leak, but if it doesnt that's probably because I havent covered wherever the leak is coming from. Performance and reliability ratings only 3, as only time will tell on these.

Rated 5 out of 5 by from Cementone Roof Repair Had a leak from flat roof over bay window, went on easy and dried no problem. Smaller tin was good as saved from buying 5 times as much as required.

Rated 5 out of 5 by from Works well I would recommend this sealer, used it on a bay window over the lead roof which was leaking. Went on easily and dried quickly. Cured the leak, a lot cheaper than replacing the lead flashing.

Concrete slab roof

Can this be used on a concrete slab outbuilding roof that is currently allowing water ingress due to it having hairline cracks within it ? Thanks in advance.
Asked by: GeoffA65
Bostik Flexacryl Instant Repair for Roofs can be brushed straight from the tin onto substrates such as old roofing felt, asphalt, bituminous roof coatings, cement, concrete, lead work, metal, brickwork, slate and rigid PVC. Since it contains fibers to bridge gaps, it will cover the hairline cracks.

Difference between this and flat roof version?

I have been to buy this but the product given to me was different, it was for flat roofs only. Is there any difference between the two and will the flat roof product work on a clay tile roof?

Is this suitable for sealing concrete chimney crowns?

Asked by: Adam10001
The Bostik Cementone Roof Repair Compound is a solvent based fibre reinforced acrylic roof coating the can be applied to substrates such as roof felt, wood, concrete. UPVC, metal and bitumen among others. The product can be also be applied to vertical substrates such as upstands on a roof and so it could be applied to a concrete chimney crown if it is either ornamental or not subject to any heat or sparks from a heating system that it may be attached to, however if it is subject to such conditions, then the product is not recommended.
