Lime plaster has been used in construction for thousands of years. Burning raw limestone at high temperatures 825 °C(1,517 °F) transforms the mineral into substance reactive with water.
In its raw form limestone is a sedimentary rock primarily composed of calcium carbonate. Deposits commonly form in warm shallow marine waters from the decomposition of shells and the accumulation of oceanic sediment. This biological formation is the most common though chemical formation of limestones can occur mostly in area of mineral rich water. Limestone is categorized by its process of formation as well as its total chemical make up. Trace and other minerals can greatly effect the specific qualities of Lime stone in construction.
When we specify a lime plaster we can base our mix design on a matrix of desired outcomes including: Color, texture, strength/weight ratio, density, application method, substrate, hardness, compressive strength. By going beyond pulling a product off the shelf we are taking plastering back to more artisan roots. Through our work with communities around the world we help this craft remain relevant. Advising entrepreneurs, manufacturers and government agencies on production and regulation standards.
