What is lime plaster

Marmolaz lime plaster delivers unadulterated finishes that have stood the test of time. These beautiful, rich, and durable finishes have no synthetic ingredients or chemical additives. In addition to their naturally pure composition, they are earth-friendly in production and application, ensuring the health not only of personal living spaces but of our shared environment.

Limestone first goes through a process of calcination whereby pulverized lime is kiln-dried at a high temperature thereby removing moisture and calcium dioxide and resulting in quicklime, a caustic form of lime. To arrive at slaked lime, a form of lime safe to handle, quicklime is slowly rehydrated. The slaking process for our products is three years, an exceptionally long time in the industry but a period that produces the strongest material that is the base for our lime plasters and lime wash. Slaked lime is a material that wants to, and actually does, return to a state of being limestone. It does so through contact with carbon dioxide and moisture. This process happens slowly but actively. Walls finished with lime materials act as natural air filters as they absorb the carbon dioxide in the atmosphere. A limed surface is thus not only a surface superior in its bonding capacity and durability but also in maintaining cleaner air.

The time we are living in has seen an ever-growing awareness of the toxins in synthetic paint and the damaging effects they have on our environment, beginning with a single room and rippling out in ever wider circles to ultimately encompass our oceans and the very air we breathe. Of the 10,000 chemicals contained in standard household paint, 300 are known toxins. Among the most harmful are volatile organic compounds (VOC). The VOC content of paint is what causes chemicals to linger in our freshly-painted rooms for years and what contributes on a much wider scale to the destruction of the ozone layer. The character, purity, and appearance of our products are unachievable in modern paint. Their integrity is unimpeachable.
