How do you treat rust on metal outdoor furniture?

[#1]

For a rusty metal outdoor furnishing, start by sanding the rusted areas back with 120 grit sandpaper to remove the bulk of the rust.

Then coating the rusted areas with Bondall 250ml Ranex Rustbuster Rust Converter. This will bind the rust and prevent it from continuing to corrode the surface.

To paint your furniture, apply White Knight Rust Guard Medium Grey Metal Primer Paint to all surfaces, followed by White Knight Rust Guard Paint in your preferred colour. - MitchellMc

I just recently repainted an outdoor mirror frame which had started to rust out.

I used a wire brush drill attachment and painted the worst bits with a rust converter. I wiped everything down with sugar soap then used Zinsser Bullseye 123 which is a primer, undercoat and stain blocker. Top coated with semi gloss Dulux Aquanamel. A light sand in between coats and it came up looking great.

The colour I used was Dowager Grey, which I think was a Taubmans colour. The Aquanamel will dry quite quickly, but needs to have time to harden. Preferably after painting the final coat, leave in the sun for as long as possible to "bake" it. This might take a few days. Good luck. - kacharash4

Mitchell, I need to work on a combo small table - wrought iron frame and mosaic top. The top was never sealed and the iron is starting to deteriorate so I'm not sure how I should approach this - tackle the wrought iron first, get that cleaned up? then seal the top - using what?? 

Many thanks :).

Hi @hakeae,

Apologies for the delay in response, we have been dealing with a great volume of enquiries at the moment.

As @MitchellMc is currently offline, allow me to help.

Start with the wrought iron as it will be a bit messier.

Do you plan on painting it or keeping it as is?

You should start by removing as much surface rust from the iron as possible. A wire brush will do a lot of the work, but if there is some troublesome stuff, use 80 grit sandpaper.

If you plan on painting the iron, use a metal primer such as Dulux Metalshield Etch Primer before applying your topcoat.

Once the wrought iron is done, you should give the table-top a clean with warm soapy water and a scrubbing brush.

With the table top, it's a bit difficult because you have a combination of porous grout and non-porous glass. There are grout and tile sealers, but they will not work on non-porous surfaces like glass.

My suggestion would be to use an epoxy resin such as this Protite Clear Casting And Embedding Resin. This would create a clear, varnish-like coating that will protect and seal the top.

Let me know what you think.
