Walther Strong Self-Expanding Foam Tape is a flexible, weather-resistant expanding foam tape designed to prevent water ingress, retain heat, and provide an airtight and draught-proof seal. Suitable for both internal and external use on various surfaces including brickwork, concrete, wood, and plastics, this tape gradually expands over 2-3 hours, filling gaps and creating a secure seal with excellent acoustic and insulation properties. It's permanently elastic for long-lasting flexibility, self-adjusting to different surfaces, and UV stable for outdoor durability. The tape is weatherproof, resistant to driving rain, and prevents mildew, improving insulation. It expands between 5-35mm for a tailored fit.
