Description Product Overview ARDEX STB Tape is a self-adhesive butyl rubber tape with an integrated fleece layer, designed to provide a waterproof seal at critical junctions within wet area waterproofing systems. It is used to reinforce joints, transitions, and penetrations prior to the application of liquid membranes. The butyl core delivers high flexibility and adhesion, allowing the tape to accommodate structural movement while maintaining a watertight seal. The fleece surface promotes strong bonding with ARDEX liquid membranes, ensuring system compatibility and long-term performance. ARDEX STB Tape is suitable for internal and external applications in areas such as bathrooms, balconies, laundries, and kitchens.
