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.

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