What is limewash
Limewash is produced from crushed limestone combined with water to form hydrated lime. Hydrated lime, in its powder form, is used in a variety of production and manufacturing processes to remove impurities from other compounds substances.
To create limewash in its paint form, the hydrated lime in its powder form is tinted with natural pigments. Other natural additives also help the pigments bind to the hydrated lime and assist with cohesion of the lime to the surface that is being painted. When water is added, this limewash mixture forms a paint that results in surfaces that are mottled and matte, with a chalky texture reminiscent of suede. It adds depth and luminosity to flat walls.
Limewash paint has ancient roots, having first been used in the Roman and Mediterranean regions. It offers several natural benefits: it is nontoxic, and eco-friendly. Its high pH level makes it resistant to bacteria and mold.
Limewash is also highly breathable, meaning it allows moisture to pass through the surface. This is important for brick and render, as it helps to prevent the buildup of moisture inside walls, which can lead to issues like damp, mold, or structural damage. The porous nature of limewash ensures that any trapped moisture can evaporate, keeping the structure dry.
Due to its chemical makeup, it is known for improving air quality and removing impurities. Additionally, because limewash paint is low VOC (volatile organic compounds), it has virtually no odor during application.
Limewash paints are suitable for use almost anywhere, except in surfaces that are more prone to wear and tear.
