In this video I treat a base panel of a has heater which has started to show early signs of rust (see link in description for Kurust). I want to treat the rust to stop it effecting any more metal and provide a solid base to paint further Hammerite paint over. To Treat the rust using Hammerite Kurust you need to remove as much paint and rusted metal as possible, trying to achieve a flat smooth finish of which to apply the Kurust rust treatment to. As the area I was treating was small and has awkward access I choose to use wire brush attachments to strip the paint back to bare metal and remove the rust. A grinder or flap / abrasive disc would be better but access is limited on this occasion.
Once the paint and rust is removed, apply the Kurust with a clean brush, I probably apply a little too much while making sure I had good coverage, its not a problem but it will start to eat into any paint that has not been stripped so be careful when applying.
After leaving the Hammerite Kusurt rust treatment to dry for about an hour, the reaction should be complete and the metal should have turned to a blue/black colour which is not fully protected from further rust as Kusust is a full rust inhibitor.
I paint over the Kusurt with just normal black Hammerite paint. I am more concerned about getting a think coating than having it look pretty as the metal plate being treated will not be seen at all when installed and I just want to ensure the metalwork is fully protected, if I was treating an area which would be visible, I would ensure the finish was carried out to a high standard (as can be seen on a sliding door repair on my youtube channer CamperConverter. Thanks for watching.
