wedi Waterproof Sealing Tape – 5" x 32.8' (US5000002)

The wedi US5000002 Waterproof Sealing Tape is a professional-grade polyethylene membrane strip with seamless fleece lamination, designed for use in showers, steam rooms, bathrooms, kitchens, and commercial wet area installations. At 5 inches wide and 32.8 feet long, this sealing tape provides robust, continuous waterproof protection across seams, joints, corners, and transitions.

Unlike basic tapes, wedi’s sealing strip is engineered with a fleece-laminated surface that bonds permanently with wedi Sealant 620 or any appropriate polymer-modified thinset. This ensures full integration into wedi waterproofing systems, from the Fundo shower base to Subliner Dry sheet membranes and Vapor 85 wall panels.

This sealing tape not only prevents leaks but also bridges minor cracks and joint movements, safeguarding against tile delamination, mold growth, or structural water damage. It can be applied quickly with minimal tools, making it an ideal solution for both professionals and experienced DIY installers.

Whether you’re waterproofing a new custom shower or retrofitting an old tiled wall, wedi US5000002 offers unmatched reliability, flexibility, and long-lasting performance.
