Hi,
I am a little upset because I sanded off and re-painted my metal stairway running upto my flat.
How should I protect my metal work which seems to rust too quickly?
I think I did this about 4 years ago and still have some of the paint in working condition in the shed.
But the paint has already started bubbling and flaking off when the main angle irons underneath holding a large concrete slab.
I guess the reason is because the area under the slab cannot be accessed and cannot be painted so water will always be able to reach the bare metal. from the other side.
Last time I used a yellow zinc primer and a hammerite black top coat. My decorator recommended maybe using a chromium based red primer.
Any thoughts? so I don't have to do this again in another 4 years.
Thanks
