TRITON® Seam Tape (5″ x 75′) reinforces the seams and transitions in your tile assembly, keeping backer boards, membranes, and corners watertight where they’re most vulnerable.

Its fleece surface bonds securely with waterproofing systems to form a continuous, vapor-resistant barrier, built for showers, steam rooms, and other demanding wet-area installations. The flexible construction wraps easily around corners and joints, while resisting salts, oils, and chemicals for lasting performance in residential and commercial jobs. Installs easily with thinset and is an essential part of the decoupling mat and Waterproof Backer Board install.
