Re: Rusting steel posts 9Jan 02, 2023 7:18 pm Nationalist I still haven't had it fixed ๐Had a few interruptions and waiting for a painter ... 2 quotes so far. One for 2 pack paint and the other for applying 2 coats penetrol and one coat epoxy. Interesting. Thanks. I've written today to a guy in Perth that does mobile sandblasting and application of rust inhibiting coating - I'd then paint over myself with some sort of epoxy enamel in the colour we want. I've asked the sandblast / steel repair guy whether for me the penetrol route is really going to help rather than cleaning up the steel surface more actively. I've got similar issue to you with steel support posts for a deck that sits at second storey height - lines up with our living space on second storey. Don't know if I'm going down the right road but I'll let you know if the sandblasting guy gets back to me and if progress is made.

The painter ground away all the rust using a Josco 125 or 127mm wire wheel brush? It was a difficult job and he mentioned that a sandblaster would probably be better (they do make a mess though he said). But he did a great job and got all the rust off which is important. He did a coat of Penetrol, then a coat of Cold Gal and then 2 coats of Rust Guard Epoxy Enamel topcoat. The soil around your posts looks like it will continue to cause a problem with rust. You need to dig down to find the concrete footing. What happens from there depends on how bad the rust is. You might need to create a concrete footing if there isn't one? if it's rusted through you might need to replace the rusted section of the post? It sounds like you're in Perth and I'm on the east coast, otherwise I'd recommend the painter i hired. Re: Rusting steel posts 11Mar 17, 2023 3:13 pm Nationalist Hi Tsfreo, I've just had mine done.

I had a few people look at mine and conclude that I am too close to a neighbour to sandblast (because of mess). Without sandblasting the problem most likely to keep coming back for me. So, in the end, I am going to replace my four deck support posts. Custom made steel posts, galvanised and set in proper concrete footings. Is going to cost thousands, but is the proper way to fix them more permanently in the situation I am in. Of course, actually getting a final quote and commitment to do the job is proving hard. Huge tradie/build demand in the West. Re: Rusting steel posts 12Mar 17, 2023 4:17 pm tsfreo Nationalist Hi Tsfreo, I've just had mine done.

I have some galvanized steel on my house already rusting - was probably made in China. Re: Rusting steel posts 13Mar 17, 2023 8:11 pm Seriously I would go for the zinc anode primer and wire brush. Hard to reach places can be done with a hand held sandblaster. It's not a huge mess at all. You could even drill a hole in each post and use rust converter as a spray inside the post. Get another 25 years out of those posts. Re: Rusting steel posts 14Mar 17, 2023 8:38 pm Ardo Seriously I would go for the zinc anode primer and wire brush.

Get another 25 years out of those posts. Fair enough. I've dug out two of mine that were not set in proper footings and they are in very bad condition below. Plus the welds at the top of a couple are pretty shot. I may be going over the top, but my kids play on that balcony and I don't want to have to worry about it.
