Preparing rusty metal Victorian skylight

Aug 20, 2020 Last reply: 5 years ago 5 Replies

We have several opening skylights which are rusty inside. Having cleaned off all the old paint and surface rust, the surface is slightly pitted with ingrained rust. Best preparation before painting? Jenolite? Assuming Jenolite does the job, follow by primer, undercoat and ordinary gloss top coat?



Thanks!


angle grinder & wire wheel. I guess you mean phosphoric acid. You'll need that or HCl to get in the nooks the grinder won't.

Depending on how long you want it to last, you could electroplate it in situ with zinc.

Hell's teeth! I'm thinking in terms of gentle DIY decorating! :-)

Hmm, at my old school they had windows like that, they used rust inhibiter some zinc paint the hammerite over the tope they appear to still be there according to other people who went there and I'm talking about the 1950s! The hammerite stuff I remember cos I never did understand how a paint dried with a non smoothe surface. I was only a child at the time. Brian

Yes I was thinking the same, one assumes its a conservation area, if its not badly compromised what I said in my last would probably still be ok today. Mind you that zinc and the rust inhibitor might today be seen as dangerous I guess and replaced by some other stuff that does not work so well. grin.

Which bit don't you like? Zinc plating is easy to do. HCl is not the friendliest chemical but it makes rust removal quick & easy.
