The backbone of a true waterproof system. ARDEX TLT Waterproof Seam Tape seals the seams, overlaps, and joints where leaks start — bonding with ARDEX TLT membranes and adhesives for continuous, floor-to-ceiling protection. Flexible enough to move with the substrate without breaking the seal, and quick to install with thinset or waterproofing compound.
