Flexible bitumen bonds to common roofing substrates to form a permanent watertight seal. Simple hand application and a seam roller enable fast repairs on valleys, gutters and flashings.
Instant watertight repairs - thanks to the flexible bitumen strip
Self-adhesive bitumen composition creates immediate adhesion to compatible substrates, forming a continuous barrier. The material remains pliable so it follows contours and fills gaps without special primers.
Rapid sealing stops leaks at source, allowing roofs and gutters to remain weatherproof straight away. Minimal preparation means faster repair times for urgent leaks.
Quick application with basic tools - with hand pressure and a seam roller
Aggressive adhesive backing activates under hand pressure, and a seam roller consolidates contact for a stronger bond. No primers, heating or specialist equipment are required for standard repairs.
Simple two-person patches or solo repairs are achievable on site, saving time and simplifying routine maintenance. Tradespeople can complete multiple fixes without hauling extra kit.
Versatile substrate compatibility - thanks to broad adhesion range
Formulated to bond to brick, masonry, slates, metal, terracotta tiles and roofing felt, the tape adheres across different textures and porosities. Surface contact and pressure are the main requirements for secure adhesion.
Useful for a wide range of repair tasks, from sealing valley gutters to mending drain pipe and gutter leaks. One roll covers several repair types without swapping materials.
