Paint Type

Casein Paint

Casein paint is a water-based paint that uses casein, a milk protein, as its binder. It dries quickly to a matte film and becomes increasingly water-resistant as it cures.

Casein paint surface compatibility

Casein paint works best on rigid, porous supports. Because a cured casein film is relatively brittle, flexible supports such as stretched canvas are generally avoided.

Surface Compatibility Preparation Primer or ground Finish Guide
Painting Board Excellent when rigid, porous, and properly prepared Use a clean, dry, dimensionally stable board and smooth the surface as needed. Use a casein-compatible ground or casein gesso when a prepared painting surface is wanted. Allow the paint to cure fully before optional polishing or another compatible protective treatment.
Wood Panel Excellent on stable porous wood with suitable preparation Use clean, dry, rigid wood and remove dust, grease, wax, or unstable existing finish. Prime with a casein-compatible binder or ground when needed to control absorbency and adhesion. Let the casein film cure thoroughly before adding any optional compatible finish.
