What do I need to prep rusted pipe fence for paint

[TxMN]

Recently purchased property that has a nice pipe entry, previous owner built it about 2 years back and never painted it. Is there any way I can prep the mildly rusted pipe to get a paint job that will look good and last. Any suggestions to best paint for this application is appreciated.

ideal... sandblast..enamel primer and good quality enamel equipment paint

OSPHO (Phosphoric Acid) as a primer, and a 2 part marine epoxy paint.

But, best would be....."Amerlok" (Ameron Corp.)which is a commercial 2 part epoxy coating, used on water towers and steel bridges.

POR 15. Best stuff I've ever used.

UV will fade POR 15.

POR-15 is good stuff! However the one person is correct, it is not UV protected. But neither are mist rust convertors.
I would use a rust convertor as a base treatment to rust after having knocked of the worse of the rust with a wire brush.
I would follow this up with a self etching primer (this is not a common primer!) look for ‘self etching’ on the label!
Then your choice of paint. If you want the hard finish of an epoxy, go for it in your choice of color!
However it is my opinion that epoxy paint without prep will chip off!

The rust is not that severe, none of it is flaking, not even close. Very mild rust, no build up. I was wondering if some solvent type treatment, apply and come back next day and paint. Can’t recall where I read or was told that, but most importantly can’t recall the specifics on the “solvent” material.Very nice entry to the property, can’t imagine leaving it like it is, would be very nice painted.
When you say rust converter, is there a brand or trade name, this is something I have zero experience with, but I believe it may on the right track to what I had in mind. Thanks.

Just quickly knock off loose rust with any method you want. Course sand paper, wire brush, ScotchBrite, etc. If not loose and minor just leave. Wipe with fast drying solvent. Paint with rusty metal primer such as Rust-oleum. When dry follow up with enamel of your choice compatable with primer. There are direct to metal paints that can be used on slightly rusted surfaces but I think they don't last as long.

For applying paint we would use a painters mit. Very fast method.

also make sure the welds are well prepped.
Spoke the the chemist of GEM Rust Remover......converts the rust into an inert phospate......his procedure is remove light rust, coat with primer, use favorite paint.
Most common failure points are the welds.

So another point to take into consideration.....good luck with your project......and...lastly......gloves, google......

Can use just this with a pressure washing no wire brushing! This stuff needs no topcoat or apply your favorite color. Used on truck frame couple months back and waiting to see what the winter will do to it. Used on off shore oil rigs, so has to be pretty tough!

You cant paint whats in the ground so it will rust upwards anyways.

Best is to disassemble, galvanise and reassemble. That makes it good for 30 years

If it's just rust bloom and not flaking, then I'd just paint over it with the following:

Wrought'n Harv, another member on here taught me about mixing Rustoleum rusty metal primer with the Rustoleum brown leather top coat in a 1:1 ratio as a single step paint system that lasts. That's all I've used for the last 2 years on all my pipe fencing. It goes on easily with a paint mitt, lasts and is easy to touch up if needed. It's a nice rustic look and if any rust starts to develop, it doesn't look bad.

If you're planning on a fancy look that requires a colored top coat, then I'd suggest you go "all-in" with a complete metal prep, zinc rich epoxy primer and then an epoxy top coat. If not, then the system listed above is about the best I've found.

I agree totally after years of dealing with various rusted items- like water tanks, pipes etc. Remove any flaking rust with a wire brush but leave any other mildly rusted areas intact - the rust converter needs it to complete the chemical process. Don't overdo the converter - just wipe or brush it on, then leave it for a few hours to do its magic. The color will change to black. Then paint it

I’ve used POR-15 on a lot of Jeep parts, that stuff is tough, but the smell will about knock you over. It will fade, but you can also top coat it. I’ll do most anything to avoid using a wire brush.

The strongest phosphoric acid product you can buy without a license is a product called rust blast By KBS products.
for best results wipe away any loose scale or flaking rust the best you can. then spray or wipe on wearing rubber or latex, or chemical gloves. reapply after 10 to 15 minutes or before the surface becomes dry if possible. For badly rusted areas apply then wrap in plastic wrap.
This product does not convert rust or oxidation but eats it away and leaves the bare metal but has no effect on paint unless there is rust under the paint.
when allowed to dry it will leave a faint white film of zinc phosphate which can be directly painted over. if you want a superior paint that will last nearly forever use the KBS topcoat
You can call Eddy Lucast @ 203-228-1961 and get the full low down on how this stuff works

I'm going to use my belt drive pressure washer to blast the flaking paint due to rust off my entry gate area (2" pipe), coat with Ospho and paint. I've used POR before and I'm not impressed, no better than Ospho.

Pressure wash and then just paint it with Rustoleum equipment paint. The white and silver seem to hold up better to the sun, you are still going to have to touch it up every now and then, but no matter what you do you will have to touch them up from mowing damage and everything else that seems to hit them. Paint is not permanent, so don't sweat it.
