It is also easy to repair lime plaster with a thin layer of plaster or limewash. Compared to cement plaster, plaster made from hydrated lime is less brittle and less prone to cracking, requiring no expansion joints. Lime as a surface finish is aesthetically pleasing, with a more ‘natural’ look that comes from the double refraction of light through the calcite crystals that are present in it. A thin layer of lime plaster on earth will not suffer serious cracks like cement stucco. Lime mixes have good workability. Lime plaster is well adopted traditional techniques that seem to be adopted since 7200BC /5000BC according to a record of archeological study. Lime not only absorbs potentially damaging carbon dioxide from the atmosphere, but the amount of energy required to produce it in the first place is less than is required for the production of cement and, as it can be produced on a small scale, there is less impact on the local area. Breathability (when used internally & externally) Lime products are more vapour permeable than conventional materials. In other words air can pass through it in a way that doesn’t happen with a denser material like cement, or polymer-based renders and plasters.
