Lime plaster is also flexible so can cope well with movement in buildings - plus, it has a beautiful soft appearance that does justice to the character of older properties. It has been used for thousands of years and, unlike many modern cement plasters, is breathable.įor this reason, it is highly suitable for period properties where it can help prevent damp issues and condensation. In winter stiffening may be extended to more than one day with hardening more than two days.Lime plaster is made up of a mixture of lime, sand and water, often with added fibres such as animal hair to strengthen the mix and to ensure a good bind with the walls.
