Product overview

Where is it used?

  • Ampacoll XT can be used internally or externally and has been optimised to withstand the more challenging conditions found externally.
  • The breathable tape is suitable for taping all types of internal and external breathable membranes and vapour control membranes.
  • Ampacoll XT can be used for taping all types of timber boards such OSB, ply, MDF and wood fibre boards with the use of primer.

How is it used?

  • Surfaces should be clean, dry and free of dust before the tape is applied.
  • The paper backing needs to be peeled off prior to use and can either be cut to length and then applied or applied straight off of the roll.
  • On lightly textured boards like OSB a roller should be used to firmly press the tape into position.
  • If you are taping to concrete/masonry or wood fibre boards the Ampacoll Primax Primer should be applied and left to dry first. This ensures that the tape will stick properly to these surfaces.

  • Each roll of Ampacoll XT tape is 100mm wide and 25m long.
  • For taping OSB boards allow 4-5m per m2 of wall/roof.
