  • To ensure that regularity of colour is achieved always mix a sufficient quantity of Roughcast for the area to be rendered into a bath or box. Do not add any further water to the mix in the gauging box on the scaffold
  • Throw the Roughcast on to the surface of the Dash Receiver while the Dash Receiver is still green, using a dashing spoon. Do not go over semi-cured areas to fill in misses, as this can lead to inconsistency of colour
  • Protect from water during set
