Your Guide to Bare-to-Finish Solutions for Metal Corrosion

Learn all about how to solve your corrosion problems on metal surfaces at exterior areas.

What Causes Corrosion?

When moisture, salts, and pollutants remain on metal surfaces, oxidation can occur and gradually lead to corrosion. Nippon Paint’s Bare-to-Finish Solution forms a durable barrier that helps block moisture and withstand environmental exposure, from primer to topcoat. Discover from the Nippon Paint House Pakar why a complete system is essential for lasting corrosion protection.

Prolonged Moisture Exposure

Constant exposure to rain, condensation, or high humidity can initiate oxidation on metal surfaces, gradually leading to rust formation and structural weakening.

Salts and Environmental Pollutants

Salts from rain or road spray, along with pollutants, can make metal corrode faster by damaging its surface and protective coating.

Insufficient Protective Coatings

Worn, damaged, or improperly applied coatings can expose bare metal, allowing moisture and contaminants to penetrate and accelerate corrosion over time.

Corrosion on exterior metal surfaces can be effectively treated using Nippon Paint’s Bare-to-Finish Solutions. As products in the system solutions work well together, it can help to restore strength, durability, and a smooth, even finish on exterior metal surfaces, ensuring long-lasting performance.
