About this product
Thompson's Emergency Roof Seal is a 2.5 litre black roof repair coating suited to larger repair projects across various roofing materials. It cures into a flexible, weatherproofing membrane that repels moisture while sealing and repairing the substrate beneath.
The formulation contains added fibres for extra tensile strength and crack bridging, giving a tough repair to leaking or damaged roofs. It can be applied in all weather, on wet or dry surfaces, and even underwater, offering immediate protection. The breathable coating still allows trapped moisture within the substrate to escape.
Supplied in a tin with a resealable lid for convenient storage between uses.
