Process of Jointing & Finishing

Surface Preparation

  • Clean the substrate and remove loose material.
  • Dampen or apply a bonding agent on smooth/absorbent surfaces.
  • Set level screeds as depth guides.

Base Coat Application

  • Apply the Coat Plaster between the screeds to build thickness.
  • Rule off to a true, level plane with an H-rule.
  • Fill any hollows and re-rule.

Keying for the Finish

  • While still green, key the surface with a scratching comb.
  • Allow to firm up before the finish coat.
  • Protect the surface from rapid drying.
