Benefits of These Materials:

  • Crack resistant but include the natural micro cracks
  • Breathable
  • Wets and then dries out fast compared to cements and mortars
  • A natural biocide being mold resistant due to its pH content of 11-12.
  • Has proven itself with the test of time (centuries)
  • Natural and classified as a green product

STUCCO GRASSELLO: Grassello is the finest of all the Italian plasters. It is smooth calcium-based lime stucco. Composed of naturally occurring minerals, this medium creates rich, deep and lustrous effects that yield highly polished stone such as marble. It can be tempered to resemble soft suede like qualities with minimal sheen. It is found today as a prestigious coating on walls and ceilings.

STUCCO MARMORINO: As a plaster decoration used on walls it dates back to the Roman times, became popular 500 years ago during the Renaissance period and is having its return again. Made from crushed marble and lime putty it has the ability to be tinted to create many textures from polished to natural stone. You often see it in public buildings, restaurants, and bars. Its waterproofing and anti-bacterial properties make it desirable for bathrooms and other damp areas. It may be used for indoor or outdoor.

STUCCO TERRA: This lime-based plaster composed of marble dust and other mineral components is designed to obtain a translucent marble sheen when burnished. This can be tinted with any combination of natural pigments.

STUCCO TUSCANY: Tuscan style evolved through layers of history, taking cues from the earliest metal craft and pottery before coming into popularity during the Italian Renaissance. In Tuscany one finds frescoes (the art of painting on fresh, moist plaster with pigments dissolved in water), cracked and worn by time, still vibrant with original pigment, depicting ancient gods and life of the late Roman empire.

STUCCO TRAVERTINO: Travertino plaster is a medium-large size grain plaster achieving its name because the finished look has very strong resemblance to that of Travertine.

VEILCALCE: (pronounced val-kahl-chay) Meaning “old lime” it is the milky liquid that gathers at the top of pure slaked lime. In its diluted form Veilcalce achieves an aged look on different lime plasters.

VENETIAN: (pronounced vah-nee-shun) Is designed to obtain an ancient polished look. Used as early as 900 B.C. by ancient Egyptians it was brought back for more common use in the 1500-1700’s for palaces, churches, and governmental buildings.

CONDENSED HISTORY OF LIME PLASTER
For thousands of years (as early as 6000 BC) lime has been a key binder for mortars in construction. Lime was used as the primary binder in paints and whitewashes as well. Recognized for its strength and long life, lime was used to help strengthen medieval buildings, castles, and churches. Artists throughout the centuries have preferred using lime in frescoes (paintings on plaster) because of the multitude of vibrant colors that could be created that were fade resistant.

When Portland cement was invented in the early 1800’s it became the preferred replacement for lime in construction use. Then in the mid-1900’s the use of lime plasters became of interest again in the community of builders and renovators.

Interior and exterior applications are abundant for lime plasters providing the substrates are properly primed. Because of our procurement arrangements of these products, what used to be a product only affordable to the high-income consumer are now both cost effective for our certified installers and their customers.

What is Lime?

Limestone contains calcium carbonate. It is heated and crushed at an exceptionally high temperature [1,760°F / 960°C]. (CaCO3)

The lime in this heating process is converted to calcium oxide as the carbon dioxide evaporates. CaCO3 – CO2 = CaO

Water is added to the unslaked lime and allowed to slake up to 25 months creating Calcium Hydroxide (putty lime). CaO + H2O = Ca (OH)2

This is the basis of the Stucco Terra, Travertino, Marmorino, Grassello, and Veilcalce that we use.

Now as we apply it to a surface, a carbonation reaction takes place as Carbon Dioxide (CO2) from the atmosphere is picked up and begins to evaporate the water in the material.

The result is you have limestone again (CaCO3) without any impurities. Your finished look is durable, environmentally friendly and beautiful in its natural state. Synthetics are not encouraged to be added.
