Reinforced, Instant-Setting Roof Sealant for Emergency and Long-Term Repairs
Kingfisher Fibreseal is a professional-grade, solvent-based acrylic repair compound formulated to deliver instant waterproofing for roofs, gutters, flashings, and cladding. Engineered with built-in fibrous reinforcement, it bridges small cracks and gaps, forming a tough, flexible membrane even in damp or wet conditions.
Its thixotropic grey formula ensures excellent workability on vertical and sloped surfaces without sagging, and cures to a weather-resistant, semi-gloss finish. Fibreseal is ideal for emergency repairs and planned refurbishments across residential, industrial, and agricultural buildings.
