Product Information
GoBoard® Banding is a waterproof seam tape designed to seal joints, seams, and transitions in GoBoard waterproofing assemblies. The 4.9-inch-wide band creates a continuous waterproof connection behind ceramic, porcelain, and natural stone tile in showers, tub surrounds, steam rooms, and other wet areas.
A 100-micron polyethylene waterproofing layer laminated to polypropylene nonwoven fabric provides a stable bonding surface on both sides. The flexible banding can be cut with scissors or a utility knife and fitted around joints, changes of plane, and other waterproofing transitions.
GoBoard Waterproof Seam Tape installs with modified or unmodified thin-set mortar. Embed the banding with complete mortar coverage and no voids, maintaining at least a 2-inch overlap where it meets GoBoard accessories, waterproofing membrane, or another section of banding. Tile can be installed the same day after proper application.
GoBoard Banding meets ANSI A118.10 waterproofing requirements, is rated for residential and commercial steam rooms in accordance with ASTM E96 Method E, and achieves an ASTM C627 Extra Heavy system performance rating. These tested properties make it suitable for demanding residential and commercial wet-area tile installations.
