Hammerite 5092820 Kurust, 250 ml , Blue

Product Information

Hammerite metal paint is a hardwearing covering that is corrosion-resistant and can be applied directly onto rusty metal with no need for a primer or undercoat. It’s not often we say we’re disappointed with a product and still give it a recommended award, but Bilt-Hamber products normally excel. Even on the bodywork a stone chip or scratch can soon grow into a nasty blister, and you need to treat rust properly to stop it spreading. Hammerite Kurust is a special paint used to transform rust to a clean, paintable surface in 15 minutes. We left sections of 1mm unpainted mild steel to gently corrode outside over the course of several months, then let them thoroughly dry before treating both sides with our products, carefully following the instructions.

But some minor surface corrosion had started to become visible on both sides of our sample by the end of our test period. Do you have some really rusty metal that you want to paint but you think it may be a little too rusty, even for something like Hammerite?The surprise was that the consistency was so different from that of the Jenolite liquid (p58), because it was far more clinging and waxy. Once dry, the samples were then doused daily in salty water for four weeks to encourage any corrosion to reappear. If a spray isn’t suitable for the job, we’d recommend the Bilt-Hamber Hydrate-80 for tackling larger areas, and the Hammerite Kurust for smaller repairs. For these we would also recommend a coating of protective wax such as Bilt-Hamber’s Dynax UB (below) to complete the protection and ensure the car remains rust free for many more years.

Kurust rust paint– Protect your metal - Hammerite

Let’s open the bottle up and see what this stuff looks like, I have never used it before so have no idea what’s inside. I am a fully qualified, time-served, award-winning joiner with an NVQ Level 3 in Carpentry and Joinery as well as an HNC in Construction. These stop reaction in the metal using special ingredients, which neutralise the corrosion and allow you to paint over it.If you are treating a rust bubble on the bodywork, you will want to remove as much of the rust as possible before treating or it will soon reappear under any filler and top coat. Its protection performance was impressive too, with no corrosion visible on our painted surface, and just a few specks on the unfinished surface. Shake the container well to mix the ingredients and pour the required amount into a plastic container. Dispose of contents and container in accordance with all local, regional, national or international regulations.

Hammerite Kurust is a brush on rust treatment that converts iron oxide (rust) to stable iron complexes. If you – or the MoT tester – spot some rust, then don’t waste any time getting it sorted, because it’s not going to get any better. If you are getting underneath a car, make sure you use axle stands or ramps and wear eye protection and a mask. Using the brush in the cap apply directly onto the rusty area, working well into any pitted areas, corners and edges.

An advisory in the MoT for surface corrosion is likely to mean welding will be needed the next year unless you tackle it now. Any areas that are holed will need welding, so don’t waste your time with treatment, but surface rust should be rubbed with a wire brush and then painted with a converter. We suggest starting with a small amount as you should not pour any unused Kurust back into the bottle. That’s why we were a little underwhelmed that the Hydrate-80 didn’t come out as the top performer here. The Loctite fluid was far more watery than the other treatments, which meant it soaked into the rusty surface quickly.
