KEIM Limewash is a classic, old-world paint finish with hydrated lime as the binder and uses only the finest natural mineral pigments. Limewash is a concentrated lime paint made with pit lime that has matured for at least three years. This finish provides a soft patina and slightly mottled appearance reminiscent of ancient Roman frescoes. It is extremely vapor-permeable and allows masonry walls to breathe naturally. It is entirely natural and has no allergy triggers or negative health implications. On the exterior, it must be routinely re-applied as the lime binder weathers away at a rate based on the severity of the climate. It is ideal for historic restoration of lime plasters and stucco. On the interior, these finishes are suitable for lower-traffic areas where they will not be frequently washed.
