What is Limewash?
Limewash is a traditional, breathable paint made from lime putty which is thinned with water. Our limewash is approximately 1 part mature lime putty to 1 part water. Other suppliers make much more watery limewash. Limewashes are coloured with pigments and can be used internally or externally on lime plaster, lime render, stone or brick. It works best on porous surfaces and hardens as it absorbs carbon dioxide from the atmosphere to form calcite crystals, giving it its unique appearance. Typically four coats are needed on new external render and three coats on new lime plaster.
