How KILZ Mold and Mildew Primer Works
The primer works by creating a protective barrier on the surface of walls and ceilings. This barrier helps prevent moisture from penetrating the material, reducing the conditions that allow mold and mildew to grow.
At the same time, it seals stains caused by previous mold or water damage, ensuring that they do not bleed through the final paint layer.
Key Mechanisms
- Seals porous surfaces to block moisture absorption
- Inhibits mold and mildew growth on the surface
- Locks in stains from water or biological damage
- Creates a smooth base for paint application
Surface Preparation Before Application

Application Method
- Stir the primer thoroughly before use
