Triton Platon Sealing Tape (2Mm X 30Mm X 20M) is a blue butyl tape which is used for joining Platon cavity drain membranes along the flange where any of these membranes overlap.
It is used for abutting joints, for repairs or where membranes have been cut to enable them to overlap, for example at corners, reveals, wall/floor joints or protrusions through the membrane.
It should be regarded as an excellent general purpose sealing and repair product.
