The mother-of-pearl grit obtained from seashells is one of the elements which was traditionally present in antique Venetian plasters. This is because small pieces of shell were naturally present in the sand which was used to make them.
The mother-of-pearl grit, besides containing a shiny silver color, also has elements of brown and black colors typically found in the shells. These are of the same dimension as the shiny mother-of-pearl particles and add pleasing points of color to the finish.
In Dilavato plaster, these darker parts blend in with the marble grains of the plaster itself.
For use in Marmorino Veneziano Carrara
To obtain a marmorino with a mother-of-pearl finish, use about 1 kg of the mother-of-pearl grit fine size for each container 24 kg of Marmorino Carrara (about 4%).
Add the mother-of-pearl to marmorino which has already been tinted and, using the mixing beater, mix it the minimum time necessary to obtain a homogenized mixture.
Marmorino Veneziano Carrara with mother-of-pearl has a more complex finish than normal marmorino
Because of the particular form the grit takes, it tends to leave streaks on the surface. It, therefore, requires more work and expertise to achive a good finish.
For use in Dilavato
The suggested dose per single 20 kg bag of material is 800-1,000 gram. Use particles of 1.6 mm, Medium Size.
Add the mother-of-pearl grit at the time you mix the plaster for the last coat.
For use in Stucco Lava
Use one jar of medium size Mother of Pearl into the last coat of Stucco Lava. Apply the stucco and leave it to dry 48 hours, than sand the surface with a electric sander and apply one layer of Natural bee's wax to fix the dust.
