Product Description:

Kobau Waterproofing Polyethylene Membrane Seam Tape is a high-performance waterproofing band engineered to seal membrane joints, seams, and transitions in wet-area tile installations. Manufactured by Kobau, this waterproofing tape is made from modified polyethylene and reinforced with anchoring fleece on both sides, providing exceptional bonding strength, flexibility, and long-term durability.

Designed specifically for use with waterproofing membrane underlayments, Kobau Band is installed using thin-set mortar to securely bond butt joints, floor-to-wall connections, inside and outside corners, and other critical transition points before tile or stone installation. Its lightweight yet chemically resistant construction ensures reliable waterproofing performance while maintaining ease of handling and installation.

The membrane tape features a very low water vapor permeance, making it an effective vapor retarder for showers, steam rooms, and other high-humidity environments. By preventing moisture and vapor migration, it helps protect tile assemblies, substrates, and adjacent building components from water damage, mold growth, and structural deterioration.

Kobau waterproofing seam tape is highly pliable and can be easily cut, folded, and shaped to fit complex layouts, irregular surfaces, and custom shower designs. This flexibility makes it ideal for waterproofing even the most elaborately shaped showers, bathtubs, niches, benches, curbs, and floor transitions. The double-sided fleece allows the tape to mechanically bond to both the substrate below and the tile assembly above, creating a continuous and reliable waterproof barrier.

Suitable for both residential and commercial applications, Kobau Band provides dependable waterproofing for modern bathrooms, kitchens, steam rooms, spas, swimming pool surrounds, hot tub areas, and other wet environments. It is widely used in homes as well as high-traffic commercial spaces such as hotels, restaurants, galleries, malls, and food courts. Compatible with ceramic tile, porcelain tile, marble, granite, mosaic tile, glass tile, and natural stone, this waterproofing tape integrates seamlessly into professional tile installation systems.

Engineered to meet high industry standards and inspired by German engineering principles, Kobau waterproofing membrane tape delivers high tensile strength, secure adhesion, and long-lasting performance. Its user-friendly application process makes it suitable for professional contractors and DIY renovation projects alike, ensuring consistent results across projects of any scale.
