Shower Tanking Tape

TECCA Shower Tanking Tape is a flexible, high-performance waterproofing tape designed to reinforce and seal vulnerable areas in wet room installations. When used with waterproofing membranes or tanking compounds, it provides a continuous, watertight barrier that protects against moisture ingress and long-term damage.

Its stretchable rubber core paired with a fleece-laminated surface ensures exceptional adhesion to waterproofing products and tile adhesives, making it suitable for sealing wall-to-floor junctions, internal corners, and seams between tile backer boards. Ideal for showers, wet rooms, bathrooms, and other moisture-sensitive environments, this tape helps prevent costly issues such as mould, substrate deterioration, and tile failure.

Lightweight, quick to apply, and designed for both professionals and DIY installers, the tape enhances the durability and longevity of tiled surfaces by protecting the most vulnerable junctions beneath the tile layer.
