Promac Metal Primer WB is a water-based, anti-corrosive primer designed to protect and prepare metal surfaces before painting. It is formulated to provide excellent adhesion and long-lasting protection on both mild steel and galvanised iron, making it a versatile solution for metal applications.
 
This primer helps prevent rust formation by creating a protective barrier against moisture, chemicals, and environmental exposure. Its modified acrylic formulation ensures strong bonding to both new and weathered metal surfaces, improving the performance and lifespan of topcoat systems.
 
Being water-based, it offers low odour, easy clean-up, and safer application, making it ideal for both DIY users and professionals working in indoor or outdoor environments.
