Ronseal Thompson's Emergency Roof Repair Mastic 750ml

Thompson's Emergency Roof Repair Mastic, developed using advanced technology from North Sea oil rigs, offers a high-performance, trowel-applied solution for urgent roof repairs. Engineered with added fibres and a high solids content, this mastic is designed to fill, plug, and repair cracks and splits in roofing materials, directly targeting leaks at their source—even in underwater conditions.

This all-weather mastic features a hydrophobic formula that actively repels and displaces water, instantly forming a watertight seal upon application. No curing time is required, providing immediate weatherproofing protection for peace of mind in emergency situations.

Perfect for a wide range of roofing surfaces, it adheres to virtually any material—even under water—and is suitable for use on flashings, gutters, roof lights, and valleys.
