Lime has been an important component of mortars for over 2000 years. Thanks to their fine particle size, lime mixes are able to fill minute voids more deeply than other construction materials. However, the uncured material that we apply on our walls is also called lime plaster – but this time, it is calcium hydroxide. Given that lime is highly alkaline, working with it can severely burn skin. Lime gives off a double refraction of light through calcite crystals, combining luster with soft texture. When you use lime plaster or mortar for building, you won’t get condensation on the surface of walls. Why Use Lime Plaster for Natural Building. Lime has been used as a building material for centuries thanks to its … My goal is to educate others about this great planet, and the ways we can help to protect it.
