Rust-inhibiting primer systems

Dulux Metalshield Rust & Metal Primer is a water-based rust-inhibiting primer for ferrous metal elements on facade and balcony structures — steel lintels, balustrade posts and rails, window frames, metal fascia and architectural metalwork. The zinc phosphate rust inhibitor passivates bare steel surfaces and provides a corrosion-resistant bond coat for the subsequent enamel or metal topcoat. Surface preparation is critical — all rust, mill scale, and contamination must be removed before priming (minimum St 2 hand tool cleaning, ideally Sa 2.5 abrasive blasting for severely corroded elements). The primer must be applied to clean, dry metal and topcoated within the manufacturer's overcoat window. Confirm the current DFT, coverage rate, surface preparation standard, and topcoat system compatibility from the current Dulux Metalshield TDS before specifying.

Wattyl Killrust Primer is part of Australia's most established rust-inhibiting paint range for steel and ferrous metal elements in architectural and industrial applications. Killrust products have a long history of use on steel facade elements, balustrades, gates, and metalwork in Australian residential and commercial buildings. The rust-inhibiting primer is formulated to provide excellent adhesion to properly prepared steel and acts as the corrosion-resistant bond coat for subsequent Killrust enamel topcoat application. Wattyl Killrust is widely available through Bunnings, trade paint centres and independent paint retailers nationally. Confirm the current product designation, coverage rate, surface preparation standard, and topcoat system from the current Wattyl Killrust TDS before specifying. Wattyl has both solvent-based and water-based versions in the Killrust range — confirm the appropriate product for the application.

Haymes Metal Guard Rust Inhibiting Primer is an Australian-manufactured rust-inhibiting primer for steel and ferrous metal elements. It incorporates a zinc phosphate rust inhibitor and is formulated to provide strong adhesion to prepared bare metal and sound existing coatings. Suitable for steel balustrades, window frames, lintels, and metal fascia on Class 2 strata and commercial buildings. Haymes has strong trade distribution in Victoria and southern Australia. Confirm the current product range, DFT, coverage rate, and topcoat compatibility from the current Haymes Metal Guard TDS before specifying.

Taubmans All Weather Metal Primer is a rust-inhibiting primer for steel and ferrous metal elements with wide availability through Bunnings and national trade paint outlets. It provides a rust-inhibiting bond coat for subsequent exterior enamel topcoat application on metal facade elements including balustrade rails, window frames, lintels and metal fascia. Confirm the current product designation, DFT, surface preparation requirements, and topcoat compatibility from the current Taubmans TDS before specifying.

Solver Metal Primer is a rust-inhibiting primer for steel and ferrous metal elements in exterior facade applications. It provides a rust-resistant bond coat for Solver exterior enamel and metal coating systems on balustrades, window frames, lintels and other metal facade elements. Solver Paints is available through independent paint retailers and trade outlets in eastern Australia. Confirm the current product designation, DFT, and topcoat compatibility from the current Solver TDS before specifying.

International Intergard 269 is a high-performance two-pack epoxy primer by AkzoNobel for steel and ferrous metal in commercial and industrial applications. It provides superior corrosion resistance compared to single-component primers and is suitable for coastal, marine and aggressive atmospheric environments where standard single-pack primers have insufficient corrosion resistance. Used on steel facade elements of commercial buildings, Class 2 strata exposed metal works, and high-exposure coastal balustrades and structures. Two-pack epoxy system — requires specialist applicator — mixing ratio must be followed exactly. Confirm DFT, pot life, overcoat window and topcoat system compatibility from the current International TDS before specifying.
