Anti-Rust Coatings Guide for Bellville and Northern Suburbs Homeowners
By Bellville Painters - Expert advice from the professionals
Rust is a persistent problem in the Northern Suburbs, particularly on older Bellville and Parow homes with steel window frames, gates, burglar bars and structural steelwork. In the Northern Suburbs, rust is mainly driven by rain penetration, condensation and poor maintenance.
Where Rust Commonly Occurs
The most common rust problems are: Crittal-style steel window frames on older homes; steel garage doors exposed to condensation; boundary wall caps that collect water; burglar bars and security gates never properly primed; and metal carports. Any steel surface with bare metal exposed will begin rusting within weeks in our winter rainfall climate.
The Right Way to Treat Rust
Never paint over rust without treating it first — the rust will continue spreading under the paint. Remove all rust mechanically to bare metal, apply a zinc-phosphate or zinc-chromate rust-inhibiting primer, then apply enamel topcoat. See our guide to painting older Bellville homes for more on treating steel windows and doors.
Maintenance After Treatment
Inspect painted metal annually for chips and scratches — touch up immediately before rust can take hold. A well-maintained anti-rust coating system on steel windows should last five to eight years before needing full retreatment.
