Our Lime Plaster - A Natural Wall Cladding

  • A sunbeam of light magnifies the colors of the walls
  • Red Ocher Fresco
  • Life and light on each wall and in every corner

The Greeks and Romans used lime in the construction industry for thousands of year. The know-how of the construction industry has been built throughout the lime history.

They used lime as a cementitious material, a mortar mixture of 1 part lime to 4 parts sand. They used also pozzolana cement (made of Lava) from Pozzuoli, Italy near Mt. Vesuvius to build the Appian Way, Roman baths, the Coliseum and Pantheon in Rome, and the “Pont du Gard” aqueduct in south France. A mortar mixture of 2 parts pozzolana to 1 part lime. Animal fat, milk, and blood were used as admixtures (substances added to cement to increase the properties.)

Lime is manufactured from limestone, a calcium carbonate mineral (CaCO3), by heating it to a high temperature (about 20000 F) to separate and drive off the carbon dioxide (C02) from the carbonate (CO3) molecule, leaving Calcium Oxide (Ca0). This is called calcinations or burning. Calcium oxide is used to make slaked lime (calcium hydroxide) by adding water.

Slaked lime is used to make mortar for building. Soft when first mixed, with time it absorbs carbon dioxide from the atmosphere and hardens as it reverts back to calcium limestone.

HYDRATED LIME ADVANTAGE:

  • Permeability to water vapor.
  • Fully waterproof.
  • Ultraviolet and thermal shock resistant.
  • No shrinkage or cracking.

Our lime plaster is a rendering of mixed binders highly elaborated, partly made of slaked lime, mineral load, fine thin and regular silicates, ocher and natural earth pigments premixed in factory, ready to use by adding water. It can be directly applied to any Stucco coating system, Western 1-Kote or Three Coat and replaces the final stucco coating and paint.

Any type of finish, floated, trowled... can be achieved in one coat of 1/8", this due to the weak density of slaked lime. One bag of 66 pounds will cover an average of 100 square foot.

Inside wall finishes, (lime wash, tadelack, Italian Stuc) are also premixed, ready to use by adding water, made of slaked lime, with or without silica and ocher pigments (See our technical data for additional information).

They can be directly applied onto dry walls by using a brush or a trowel, after laying on an primer. For a whitewash, one bucket of 22 pounds will cover up to 540 square foot in two lays.

With our coatings, lime may cohabitate with metal, glass, concrete, wood... and offers in contrast or in harmony, in breaking up or in continuity its stretched, smoothed, dull surfaces, its felted epidermis, its mineral roughness, its color compositions and merging...
