Casein Primer

The Professional Foundation for Authentic Mineral Finishes: Unlike standard liquid acrylic primers that form a smooth plastic barrier, our dry-powder Casein Mineral Primer is engineered specifically for natural wall finishes. Formulated with pure milk casein protein and fine calcium carbonate, this zero-VOC mineral primer creates a breathable, micro-textured surface with uniform suction—ensuring limewash paint and lime plasters bond deeply and dry without patchy lap marks.
