Process of Jointing & Finishing

First Coat

  • Using an applicator / Trowel, fill the recess formed by the edges of the sheets with Gyraffe.
  • Centre the paper tape along the joint and press it down into the Gyraffe, ensuring no air bubbles remain.
  • Immediately apply a thin coat of Gyraffe over the tape (100–150 mm wide).
  • Allow it to dry.

Second Coat

  • Apply a second coat of Gyraffe with an Applicator / Trowel.
  • Ensure this coat extends outside the first coat (200–250 mm wide).
  • Allow to dry and scrape back any build-up along the joint.

Third Coat

  • Apply a finishing coat of Gyraffe with an Applicator / Trowel.
  • Feather joint edges at least 50 mm beyond the previous coat.
  • Allow to dry, then lightly sand along the joint with finer sandpaper.
