Apply a Strie Technique
With the Venetian plaster applied to one wall, now it's time to apply a strie effect to the other walls (Image 1).
Prep the room by taping windows, doors and moldings. Place drop cloth on floor.
Apply a base coat of flax latex paint and allow to dry (Image 2).
Add three parts glazing liquid to one part latex paint to create topcoat glaze. Apply topcoat glaze in 2' sections.
Drag a dry brush from top to bottom through wet topcoat to achieve a combed effect (Image 3).
