Self-Adhesive Butyl Tape 5m
Self-Adhesive Butyl Tape 5m
Self-Adhesive Butyl Tape is a flexible, high-performance sealing tape designed for waterproofing critical areas in wet rooms and bathroom installations. Made from a durable butyl rubber compound with a fleece-facing layer, it adheres instantly to surfaces such as cement boards, timber, metal, and plastic.
Perfect for sealing joints, corners, and penetrations before tiling, the tape prevents long-term water ingress and mould growth. Its strong self-adhesive backing eliminates the need for primers or additional bonding agents, making installation clean, quick, and highly effective. Suitable for both professional installers and DIY users, it creates a reliable waterproof layer beneath tiles for long-lasting protection.
