Summary of pros and cons of lime plaster: Lime plaster is created by combining hydrated lime, sand, and water. Lime concreteis very widely used forfoundationbases of load bearing walls, columns, and under layers of floors. The lime that contains calcium oxide in high content is called as fat lime. The third coat is finished by applying a cream of white or fat called neeru with the help of a metal float. It is more desirable to apply more than one coat of the lime plaster, so before applying the second coat the mortar is dashed against the surface of the wall in a layer of 6 to 10 mm thickness with a trowel to give a good grip. Lime plasters also assist in keeping humidity levels consistent. The process of hardening is the main criteria by which the fat lime differs from the hydraulic lime.
