Typical Applications

Less Mess Multi-Purpose Joint Compound is typically used as the base coat, second coat, and topping coat in a 3-coat plasterboard or fibre cement system. It is ideal for use on internal walls and ceilings or as a topping compound over Wet Area Base Coat in areas subject to moisture or high humidity. 

Used in conjunction with jointing tape to complete the plasterboard joint, it can also be used for repairs and maintenance.

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.

Application for Recessed Edge Joints

Tape Coat

  • Fill recess in plasterboard evenly and fully with Gyprock Multi-purpose Joint Compound using a 150mm broadknife.
  • Bed in Gyprock Paper Tape centrally over the joint and cover lightly with compound.
  • Cover all fastener heads.
  • Allow to dry and harden for at least 24 hours.

Second Coat

  • When the tape coat is dry, sand off any lumps and apply a second coat, about 170mm wide, finishing slightly above the board surface.
  • Smooth the joint edges with a trowel and remove any lip to reduce sanding.
  • Cover fastener heads with a second coat of compound, laid in a different direction and extending beyond the first coat by about 25mm.
  • Allow to dry and harden for at least 24 hours.

Third Coat

  • When the second coat is dry, apply a thin finish coat over the previous coat, about 250mm wide.
  • Smooth the joint edges with a trowel to remove any lip to reduce sanding.
  • Cover previously coated fastener heads with a third coat of compound, laid is a different direction, extending beyond the previous coat by about 25mm. 

Sanding 

  • Allow to dry and harden for at least 24 hours.
  • Using 150 grit sandpaper or 150-220 grit mesh and a sanding float, carefully sand the joint diagonally across the joint to a smooth, even finish. Avoid scuffing the paper face of the plasterboard where it meets the compound.

Painting 

Apply all paints in accordance with the paint manufacturers' recommendations 

 NOTE: In wet area applications, do not use Multi-purpose Joint Compound where the wall is to be tiled. Use Wet Area Base Coat and do not apply a topping or all-purpose compound 

 

APPLICATION FOR BUTT JOINTS ON FRAMING 

  • At butt joints, follow the instructions above but extend the jointing to 250mm each side of the joint.
