steelepulse Posted September 24, 2019 Share Posted September 24, 2019 I have some steel that supports quite a bit of weight. Over the years it has started to rust and I am looking for a solution that perhaps will slow down the rust and coat the steel with some sort of anti rust properties. I know there is the gray paint used on boats and such, but I can't recall what it is. Any other options out there that are proven? Link to comment Share on other sites More sharing options...
kamalabob2 Posted September 24, 2019 Share Posted September 24, 2019 The OP would do well to look at the information in English on TOA Rust Tech products widely available in Thailand. I have bought this TOA paint product in Buriram and I see it in many paint stores and builders merchants building supply stores in Thailand.

matthew777 Posted September 24, 2019 Share Posted September 24, 2019 If you want the best then you need to look in the automotive arena. The first thing you will want to find is called a "rust converter" this is an acid that will neutralize the rust and stop the reaction from continuing. You actually don't need to remove the existing rust as you just coat the rusting metal and it will turn it black. Who uses this is auto restores and its fairly cheap and works very well. The best finish you can apply on that is a two part epoxy. Again I would recommend an automotive epoxy. They make it in Rayong and its very cheap. Go to an automotive paint store for this as well. That would be the best. One thing is you will need to spray it on as it is just a hair thicker then water and have an air-compressor. It's the best and works very very well. It's super important that you either convert the existing rust or you totally remove it. You can't simply coat rust as it the reaction between oxygen and iron will just occur under your coating. In automotive coating the expression is "less is more" Several good thin coats is simply better then a single fat thick coat. Link to comment Share on other sites More sharing options...
kamalabob2 Posted September 24, 2019 Share Posted September 24, 2019 I believe Matthew 777 is recommending the correct sort of product. I'll wager that TOA Rust Tech is that level of product. It is sold at better builder merchants, better TOA paint dealers, Thai Watsadu and HomePro in Buriram. A two part system that has instructions in English and Thai on the paint pails.

steelepulse Posted September 24, 2019 Author Share Posted September 24, 2019 Thanks everyone, very helpful. We have a number of options here in Phuket, so I will send the Mrs. out with photos of these products. "Rust converter" sounds like the best option if Hammerite or Hammered doesn't work this way.

RideJocky Posted September 25, 2019 Share Posted September 25, 2019 TOA makes a great rust converter, but be advised, they call it rust remover.RustTech is the best primer I’ve ever used. It sticks great to virtually any steel, including galvanized and stainless. We used it on several big orders we shipped to tunnel projects in Australia, and had to run it through a 20 year life cycle salt test. The project manager was so impressed with it they tried to import it to Australia to use on other components but they had too much trouble with the Australia’s version of EPA. The only big downside is that it ONLY HAS A 60 MINUTE POT LIFE. You must be aware of this, and if you are not doing the painting make sure you supervise. It’s been about 5-8 years since I’ve used it, so the pot life may have been extended, but be sure to check.Sent from my iPhone using Thaivisa Connect Link to comment Share on other sites More sharing options...
UKresonant Posted September 25, 2019 Share Posted September 25, 2019 Zinga https://www.demarctrading.com/zinga-59233.page The Thai distributor does not show the 1KG tin of brush on zinga, don't know if the dist. sells small quantities??? Brush off all loose rust and debris, degrease and slap or spray it on... quick wash next year and give it a refresh coat. Don't leave the lid off, it will dry out and you would need the solvent as well... Link to comment Share on other sites More sharing options...
seajae Posted September 25, 2019 Share Posted September 25, 2019 you really need to wire brush/sand paper it first to remove any loose rust, then dust it thoroughly, then apply rust converter, once this is done most rust paints will suffice, a hammer tone type, rust tech or similar are your best bet, its the rust converter that makes it work best though as it modifies/changes the rust so when re coated it will not break down again, did this as part of my trade for close to 40 years so I know it works and last for many years Link to comment Share on other sites More sharing options...

The stuff I used turns the rust black as well. Scrape the existing loose paint and scale, wash with soap and water and brush it on. Don’t stray it unless you have a haz-mat suit and an air-line respirator. Leave it for few days (at least overnight) and wash it off. Link to comment Share on other sites More sharing options...

Lacessit Posted September 25, 2019 Share Posted September 25, 2019 Rust converters come in two types - phosphoric acid based, and tannic acids. The tannic acids are more of a barrier type inhibitor. Phosphoric acid converts the rust to iron phosphate, which makes a good key for paint. From memory, Rust Oleum is a tannic type. I'm not sure whether chromate-based paints are still allowed. They have always been the best protection for steel. As other posters have said, it is essential to remove as much rust as possible. Relying on conversion packages to convert thick layers of rust scale will probably mean having to do it all over again in a year's time. Link to comment Share on other sites More sharing options...
