Expanding Foam Tape

Expanding Foam Tape is a BBA approved weather resistant, sealing tape which will protect against the harshest of the elements. Expanding Foam Tape is quick and easy to apply and can be used to create a weather tight seal in structural and expansion joints in walls and around door and window frames. Expanding Foam Tape is suitable for use on new or existing structures made of: concrete, masonry, metal, PVC-U, Acrylic or Timber.

When installed into a joint, the Expanding Foam Tape will begin to expand and fill up the gap. It will smooth over minor imperfections, gaps and surface irregularities.

Application:

  • The leader strip is removed from the roll of Expanding Foam Tape and cut straight with a pair of scissors at the end of the tape.
  • Approx 10-20cm of the protective release paper is peeled from the self-adhesive side of the Expanding Foam Tape.
  • Allowing at least a 10mm overlap at the top of the joint, the self-adhesive side of the tape is then positioned 1 to 2mm back from the edge of the joint and pressed against the smoothest face of the joint using a suitable tool (e.g. a trowel). The Expanding Foam Tape can be held in position until it is fully expanded in situations where the surfaces are damp or in vertical applications.
  • When starting at a blind end to the joint, ensure that the Expanding Foam Tape is over-sized in length sufficiently to allow for movement and to ensure that the joint is tight between the end of the tape and the substrate.
  • Continuously peel off the protective release paper as the Expanding Foam Tape, taking care not to over-stretch the tape.
  • When cutting the tape, ensure that 10mm per metre length is left to allow for recovery of any stretching that may have taken place.
