Ronseal Thompson's Emergency Roof Repair Mastic, 750ml, Black
Ronseal Thompson's Emergency Roof Repair Mastic (750ml) instantly seals leaks on any roof surface, even underwater.
The Ronseal Thompson's Emergency Roof Repair Mastic is a high-performance, trowel-applied mastic developed using technology originally designed for North Sea oil rigs. This innovative product can adhere to virtually any roofing material—even underwater—making it an ideal solution for emergency repairs.
Featuring added fibres and a high solids content, this mastic is specifically formulated for filling, plugging, and repairing cracks and splits, targeting leaks directly at their source. It provides an all-weather solution with its hydrophobic formula, which actively repels and displaces water during and after application. This ensures an instant watertight seal without requiring curing time to deliver full weatherproofing protection.
