Gyprock DIY Final Finish Topping Compound

Gyprocksupreg Final Finish Topping Compound

Gyprock Final Finish is a heavyweight topping compound, used as a top coat in a three coat plasterboard jointing system.

It is formulated as a topping compound for finishing joints and angles of plasterboard and fibre cement and not for bedding tapes and second coats. For these coats, Gyprock Multi-Purpose Joint Compound or Gyprock Wet Area Base Coat should be used.

Final Finish is a low VOC, pre-mixed compound, manufactured by Gyprock in Australia to stringent product specifications.

Product Options

Gyprock Final Finish Topping Compound is available in the Gyprock DIY range in a 3kg bucket.

  • 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.

Sanding

  • Allow compound to dry and harden for at least 24 hours.
  • Using a 180 grit sandpaper or 180-220 grit mesh and sanding float, carefully sand the joint to a smooth, even finish.
  • Avoid scuffing the paper face of the plasterboard where it meets the compound.
