Singapore’s First and Only Handcrafted Casein Mineral Primer.

Unlocking the secrets of ancient paintworks, our Casein Mineral Primer brings timeless craftsmanship to modern, high-performance architecture. Crafted right here in Singapore as a pure, preservative-free dry blend of natural milk protein (casein), calcium carbonate, and hydrated lime, this ultra-breathable, deep-penetrating primer isn’t just a base coat—it’s the foundational soul of your wall finish.

Simply mixed with water on-site, it acts as the ultimate bridge between existing matte emulsion paints and natural lime finishes, creating a powerful adhesion layer that allows Cloud Lime limewash to bond seamlessly onto previously painted walls.

By regulating surface absorbency and penetrating deep into the substrate, it yields a perfectly balanced, velvety canvas for subsequent limewashes.

Because it contains zero synthetic binders, microplastics, or plasticizers, it boasts a true Zero-VOC rating—delivering pristine, toxin-free indoor air quality that is exceptionally gentle on allergy-sensitive spaces.

Hand-formulated. Zero compromise. Unrivaled purity for walls that truly breathe.
