Venetian Plaster Project

Venetian plaster is a decorative painting technique used to create an effected stuccoed surface. Invented by specialized craftsmen, the plaster finish originated in ancient Rome and has been used throughout the centuries to modern times. The term Venetian plaster derives from the use of this finish in the palaces of 15th-century Venice. Fortunately, achieving the effect of Venetian plaster is now much simpler and can be done by anyone. Venetian plaster can be put on all flat surfaces, including ceilings.

Materials

Venetian plaster (tinted or neutral base)
Steel trowels, 6 inches wide
Flat blades, 4 inches wide
Steel wool (fine grit, like quadruple ott) 
Furniture paste wax
Cotton rag
Sandpaper (fine grit)

Optional
Eye goggles
Gloves
Dropcloth
Primer (tinted, preferably)
Paint tray
Universal colorants (if using untinted plaster)

Prep Work Required

Any existing wallpaper should be stripped, and walls need to be smoothed out. If there are cracks and holes, fill and sand them. If the walls are really rough, skim coating is suggested. Walls should be primed in advance, either in white or tinted with the same color of the desired Venetian plaster. Clear the room and put down a dropcloth to prevent damage to the floor. Wear eye goggles and gloves, for safety's sake.

Process

Step 1: Sand down the edges of the blades and trowels to make them sharper and to remove any excess materials.
