venetian plaster
The term ‘venetian plaster’ refers to a modern material with
acrylic additives, developed to mimic 16th century scagliola
plasterwork (which was an adapted form of the medium originating
in ancient Mesopotamia). Today’s material allows for a greater
range of colors because it does not contain lime, and offers
a more flexible working period than true, quick-drying plaster.
Expertise is crucial for achieving the marble-like finish and
desired color. The luminosity often associated with venetian
plaster comes from multiple layers of the semitransparent material
applied with a knifed technique. It can be finished by simple
burnishing, revealing the progressive ‘strata’ of the material;
waxed, for greater depth of field; and even coated with a liquid
plastic, making it suitable for commercial use.
Samples represent a range of delicate and bold colors that
can be achieved with multiple layers of one color. Because the
material is knifed on in short gestures, edges tend to be lighter
when using dark colors and darker when using light colors. Understanding
this visual activity on large surfaces is key to determining
the right value and finish for a space.
All samples shown here were burnished and waxed. The popularity
of the material has led to its production by many companies.
Green options now available, such as low VOC (volatile organic
compounds), are compatible with LEED
certification.
