Double-sided Jointing Tape is a high performance blue butyl mastic tape with adhesive to both sides, supplied in 50mm x 10m rolls for membrane joints and CPT Plus Jointing tape and 100mm x 10m for damp proof course joints and gas membrane systems.
APPLICATION: Double-sided Jointing type is designed for use in bonding overlaps in membrane, gas membrane and DPC systems.

Bond together using Double Sided Jointing tape, the lap should be sealed using Single Side jointing tape. If the membrane has been damaged it should be patched with sheets of identical thickness lapped at least 150mm beyond the limits of the puncture and bonded with Double-sided Jointing Tape and sealed with Single-sided Jointing Tape.
