"Limewash is a traditional material that has been used for thousands of years. Unlike modern paints, which lay on the surface of the substrate, limewash instead acts like a stain by penetrating deep into the pores of the underlying material. This process creates a peel-free, breathable surface, and the limewash remains vapor permeable after it cures. It is a beautiful, traditional material that mellows while it gradually wears away, and over time it develops the weathered patina that characterizes the Old-World charm of Europe.

Aside from its beauty, limewash is a traditional shelter coat that offers protection and durability to stucco, brickwork, plasterwork and stone masonry. It is non-toxic, environmentally friendly, and contains all-natural ingredients. Limewash also has hygienic properties and acts a mild fungicide due to its high PH, which is why limewash was traditionally used in hospitals and sick wards.

Recommended for historic buildings, friable masonry, and sustainable new design. Limewash is a breathable material that is suitable for historic brick, stone, plaster, and stucco, and it protects fragile or damaged masonry from weathering further."
