Before jointing fill gaps between boards and any irregular joints and repair any damaged board.
Apply manually by using a 10 or 15cm filling knife and apply the tape – milled face against the board.
Then apply a finish coat, allow to dry and finish to cover the tape.
Also cover screw heads.
Apply a tape into the ceiling joins and ensure that the concrete is free of any signs of mould-release oil.
For vertical protruding angles use a reinforced tape (metal side against the board) or a metal angle bead.
Approximately 350 g/m2 of board.
