  • Gyproc joint tape firmly embedded into jointing compound.

  • Jointing compound over taped joints and screw heads.

  • Crease Gyproc Joint Tape to the angle and bed firmly into jointing material.

  • Thistle ProTape should not be used on internal angles, as differential movement between wall and ceiling can lead to cracking of the joint.

  • For external corners Gyproc Corner Tapes are bedded with a Gyproc setting compound.

  • Two or three further applications of jointing compound are trowel applied, each feathered out beyond the previous application.

  • An equal number of applications are made to spot screw heads. Once dried, the joint treatment is sanded as necessary to achieve a smooth surface.

  • Use a mechanical sander to produce a smooth finish.
