Process of Jointing & Finishing

Surface Preparation:

  • Ensure that all fixings, screws or nails, are seated below the surface of the Gypsum board
  • Remove any dust or loose material from the Gypsum board


  • Mix Gyproc Easi-Fill®/Pro-Fill® with the clean water in the ratio of 2:1 to make a uniform paste. Continue themixing for 10 – 15 minutes to form a homogeneous mix.
  • Ensure that no unmixed powder / lumps remain in the mixed material.

First Coat

  • Using an applicator / Trowel, fill the recess formed by the edges of the sheets with Gyproc Pro-Top®.
  • Centre the paper tape along the joint and using a Taping knife / Trowel press the tape down into the Gyproc Pro-Top® ensuring no air bubble remain behind the tape.
  • Immediately apply a thin coat of Gyproc Pro-Top® over the surface of the tape (100-150 mm wide).
  • Allow it to dry

Second Coat

  • Apply a second coat of Gyproc Pro-Top® with an Applicator / Trowel.
  • Ensure that this coat extends outside the area of the first coat (200-250 mm wide).
  • Allow to thoroughly dry and scrape back any build-up of compound along the joint.

Third Coat

  • Apply a finishing coat of Gyproc Pro-Top® with an Applicator / Trowel.
  • Joint edges should be feathered at least 50 mm beyond the edges of the previous coat.
  • Allow to dry. Lightly sand in the same direction as the joint using finer sandpaper.
