Stucco Italiano Additives :: Mother of Pearl Powder

The Stucco Mother of Pearl Powder is added to decorative plaster to produce shiny dots/glints on the surface of the finish.
 
The mother-of-pearl grit obtained from seashells was one of the elements which were in antique Venetian plaster.  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 colour, also has elements of brown and black colours typically found in the shells.  These are of the same dimension as the shiny mother-of-pearl particles and add pleasing points of colour to the decorative venetian plaster finish.

 

In Dilavato plaster, these darker parts blend in with the marble grains of the plaster itself.

Mother-of-Pearl is available in two sizes:

  • Mother-of-Pearl 0.6: Particle size up to 0.6 mm
    suitable for Marmorino Veneziano Carrara
  • Mother-of-Pearl 1.2: Particle size up to 1.2 mm
    suitable for thicker plasters such as Dilavato

Packaging

  • Mother-of-Pearl 0.6 mm, bags of 1 kg   net
  • Mother-of-Pearl 1.2 mm, bags of 1 kg   net

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 for each container 24 kg of Marmorino Carrara (about 4%).

 

Add the mother-of-pearl to marmorino which has already been tinted and  mix for the minimum time necessary to obtain a uniform mixture.


Marmorino Veneziano Carrara with mother-of-pearl is more complex to 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 achieve a good finish.
