We are happy to see that more and more people understand the benefits of lime use in constructions and choose to go the “back to the roots”, using traditional building materials combined with modern technologies, for what really matters: a durable, environmental friendly construction, with a comfortable and healthy indoor living space.
Considered as one of the most versatile construction materials, lime has been used for thousands of years by Egyptians, Mayas, Greeks and Romans as binder for mortars, plasters or renders, the constructions resisting really well in time. Its use was later overshadowed by other stronger materials – but now lime regains the public attention because of its properties.
Lime has a high workability and permeability and, since it is a low-carbon material, it is better for natural constructions. Lime plaster shall be affixed in time in a tough, erosion-resistant finish, allowing water vapours disposal and increasing water penetration resistance. This helps maintain the structural integrity of the wall. At the same time, it has a low pH (it is alkaline) which does not allow fungus and mould to develop and allows the masonry to “breathe”, thus creating a better climate for persons with allergies or respiratory diseases.
Unique properties of lime
Lime is a product derived from limestone in an industrial process. Naturally occurring limestone, which is composed almost exclusively of calcium carbonate, transforms into quicklime, calcium oxide, by applying heat. When slaked with water, quicklime transforms into hydrated lime, which is a dry powder composed of calcium hydroxide. Hydrated lime can be used in a suspension called milk of lime. Once processed, these products derived from limestone have the unique ability to return to their original chemical form by reacting with carbon dioxide to eventually form calcium carbonate. This process, commonly called ”The Lime Cycle” (from limestone to limestone) helps lime to make a continuous uniform bond between mortar and masonry unit. It helps to make the mortar more permeable to vapour, allowing moisture movement, and to give the mortar the necessary flexibility to respond to the various stresses and movements of masonry.
