Cement paint is made from a combination of white cement, hydrated lime, water repellent, hygroscopic salt, zinc sulphate, calcium carbonate, silica aggregate, and pigments. These raw materials are mixed together and applied to both interior and exterior surfaces to prevent water penetration and reduce dirt collection on walls made of concrete or other materials. The manufacturing process involves mixing the raw materials together in equipment like mixers, mills, and storage tanks to produce the final cement paint product.
