Easy to apply with good coverage and adhesion despite being on sloped shed roof. Not the cheapest but the surface finish and results worth the cost.

    B. · 19 April 2025

    This is incredibly useful sealant and coating or repairing felt roofs or for extending the life of the roof. Have used it for sticking down torn roofing felt to sealing porous old felt to covering clout nail heads which were letting water in. Not cheap but well worth it.

    5.0 out of 5 stars Dries quickly and instantly waterproof.

    This works very well on flat roofs, unless you have a bad leaking roof you only need to paint the joins as that is where they will usually leak especially on garages.

    5.0 out of 5 stars Amazing product

    Y. · 29 July 2024

    I had tried other products without success but this high performance roof seal is brilliant. My felt roof had some serious cracks. 1 coat of this in the cracks, then mastic to fill them. Then a final coat over the whole roof 20' x 7'. The result looks fantastic and should last a few more years.;
