Lime plaster is a completely natural product used to create rich and velvety exterior finishes. With its low embodied energy compared to Portland cement and entirely zero VOC properties, it is an excellent environmentally friendly choice to enhance the beauty of modern and historical buildings alike.  Lime plaster produces a breathable and elastic surface which helps reduce the risk of mold development and dry rot. Made essentially from calcium hydroxide and sand, it slowly turns into limestone when exposed to free carbon dioxide in the atmosphere.
