Installation Instructions

Installing to Standards

AS/NZS2589: Gypsum linings – Application and Finishing outlines the procedures for jointing and finishing of Gyprock plasterboard in conjunction with additional details contained in Gyprock Technical Literature.      



Hand Tool Application

  • Using a broadknife or trowel, apply a thin top coat of Topping Compound wide enough to conceal the previously coated joint – about 250mm. Soften the outer edges of the newly trowelled compound with a damp brush before feathering the edges with a trowel.
  • Cover previously coated fastener heads, overlapping about 25mm.


 Allow compound to dry and harden for at least 24 hours, then sand to a smooth finish using 150 grit sandpaper or 150-220 grit mesh.


Apply all paints in accordance with paint manufacturers recommendations


NOTE: In wet area applications, a topping coat should not be used on areas to be tiled
