## Description

RedGard Seam Tape is a membrane fabric that is used for the seams between RedGard mat installations. RedGard Mat is designed differently than bonded membranes, with a sacrificial layer of fleece reinforced fabric that shears away or uncouples, when exposed to excessive substrate movement, absorbing stress and preserving the surface and integrity of the tile. RedGard Mat's bonding layers have reinforced fleece which locks mortar into the mat, ensuring strong, reliable installations.

• Required for a waterproof installation of RedGard Uncoupling mat
• For seams and changes of plane
• Part of a waterproof/vapor proof control system for floors
