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. Suitable for unpainted wood, plaster, and masonry. Limewash acts as a stain, so the substrate must be porous to ensure a successful application. We recommend a minimum of 2-3 coats for best results. 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. Limewash is a beautiful, traditional exterior material that mellows while it ages and over time develops the weathered patina that characterizes the Old-World charm of Europe. We blend our Old-World European Limewash with slaked lime putty, which ensures that the lime particles are extremely fine and can absorb into even the finest substrate.
