Duram NS2 Galvanized Iron Cleaner is a powerful, biodegradable degreaser and etching agent specifically formulated for new and weathered galvanized iron. It is designed to remove the “white rust,” factory pre-treatments, and greasy residues that typically cause paint to peel from metal surfaces.
Why Surface Prep with NS2 is Critical
- Maximum Adhesion: It chemically cleans and slightly etches the surface, creating the perfect “key” for primers and topcoats to grip onto.
- Removes Stubborn Residue: Effortlessly cuts through storage oils, fabricator’s grease, and environmental contaminants that standard detergents leave behind.
- Neutralizes White Rust: Effectively treats the oxidation found on older galvanized sheets, stabilizing the surface for restoration.
- Water-Rinsable: The concentrated formula is easy to apply and rinses away cleanly with water, leaving no oily film behind.
Ideal Applications
- Roofing & Gutters: Preparing new corrugated iron or IBR sheeting before painting.
- Fencing & Gates: Ensuring a professional finish on galvanized palisades or gate frames.
- Industrial Structures: Cleaning galvanized steel components in workshops or coastal environments.
Application Tip: For best results, use a nylon abrasive pad to scrub the surface with NS2. Once the surface is water-break free (water sheets off evenly rather than beading), you’re ready to rinse and prime.
