ACTFLEX Flex Tape 120mm x 20m Waterproofing Joint Band

Waterproofing joint band 120mm wide over a thermoplastic elastomer core, with felt flanks that soak up the membrane so the tape keys in rather than floating or peeling back. 20 metre roll. It goes over floor-to-wall junctions, cracks and control joints under polyurethane, acrylic and cementitious membranes. About 0.7mm thick with 300 percent transverse elongation, so it will take the movement in the joint.
