Trueprep Anticorrosive Primer – Direct Application Galvanised Steel Primer

Tired of watching rust slowly eat away at your metal work? This primer puts an end to that frustration. Trueprep Anticorrosive Primer goes straight onto new or weathered galvanised steel and Zincalume without the usual prep headaches. No special treatments, no complicated steps – just open the tin and get started.

What makes this different from other primers? It’s specifically engineered for galvanised surfaces, which means it actually sticks where others might fail. The alkyd resin formula creates a proper bond with the metal, while anti-corrosive pigments get to work immediately, stopping zinc corrosion before it can take hold.

The Benefits That Actually Matter

Saves You Time: Apply it directly to the metal. No need to strip back to bare steel or use special etching primers. Clean off any loose debris and you’re ready to go.

Flexible Timing: Life gets busy, and sometimes projects take longer than planned. This primer can sit for up to six months before you apply your topcoat. It won’t go hard or need sanding, so you can work at your own pace.

Proven Durability: The oil-based formula has been tested on everything from coastal guttering to industrial roofing. It even works over lightly rusted galvanised steel, which can save you hours of prep work.

Safe for Water Systems: Once you’ve applied a suitable topcoat, this primer is approved for surfaces that collect drinking water. That’s peace of mind for tank stands, gutters, and downpipes.

Real-World Performance

This isn’t just another primer with fancy marketing claims. Trueprep has been used by painters and contractors across Australia for years. It covers approximately 10 square metres per litre, dries to touch in 15 minutes, and you can recoat it the next day. The mid-grey colour makes it easy to see your coverage and provides a neutral base for any topcoat colour.

The formula works particularly well in challenging conditions. Coastal environments, industrial areas, or anywhere galvanised steel takes a beating – this primer holds up. It’s compatible with all Legacy exterior acrylic topcoats and Tuff Cote WB Enamels, giving you plenty of options for your finish coat.

What You’re Getting

Each tin contains a single-pack, oil-based anticorrosive primer that’s ready to use. You can thin it with mineral turpentine if needed, though most applications work fine straight from the tin. The 50% volume solids content means you’re getting good coverage without paying for excess solvent.

Perfect For These Applications

– Galvanised steel roofing and cladding
– Gutters, downpipes, and flashings
– Corrugated iron sheets
– Zincalume surfaces
– Pre-painted steel that needs refreshing

Application Notes

Clean your surface first – remove any loose rust, dirt, or flaking paint. For heavily contaminated areas, use Trueprep Surface Clean or similar degreaser. One coat is typically sufficient, though areas with heavy rust staining might benefit from a second coat.

Don’t apply when the temperature is likely to drop below 10°C during application or drying. This affects how well the primer cures and bonds to the surface.
