Knauf Box Ready Mastaline Jointing Compound

From bucket to box with new Box Ready MastaLine

All good tradespeople will tell you that having the right tools for the job is half the battle won.

That’s why Knauf Australia developed new Box Ready MastaLine – an all-purpose jointing compound that has been specifically formulated to use with all mechanical jointing tools such as boxes and tapers. No need to add extra water!

Box Ready MastaLine is a premixed all-purpose compound that can be applied through a box or taper straight from the bucket. The consistency is perfect and no mixing is required, saving you valuable time!

It's perfect for job sites with limited access to water.

Box Ready Mastaline can be used interchangeably with the standard MastaLine, and in all phases of jointing, coating trim and fasteners and final coating.


  • No access to water needed

  • Can be sanded by hand or electric sanders for a professional finish
