Finishing the ébauche
Let the ébauche dry before you start the next stage. This will enable you to work more aggressively and scumble in paint without removing the ébauche. If you’ve added a drying agent such as Liquin or Galkyd Gel to your paint, it should dry overnight. Lead-based pigments like flake, and Cremnitz or Flemish white also speed up drying times.
