These handrails are rusting pretty bad. My plan is to use wire brush on a drill to get the bulk of it off followed by spot sanding and mineral spirits to clean. I already tested a small section and it seems the paint comes off easily, but there are about 10 layers of it dating back to the 50's so probably lead in there.
My questions are: Do I need to get every last bit of rust out of the pitting? And should I get spray paint to do the final coating or stick with a brush?
The final colors will look similar to how it is now, white for the bulk, and a pastel for the curly accents

and here is an area I started on. Just a little bit of pitting still. (I asked in a QTDDTOT thread but there hasnt been a new one yet.)

After knocking as much as you can off give it a dose of rust converter then paint.

A brush should be fine for that finishing off.

>>1184710
Thanks, I'll pick up some of that today. A brush coat is fine for the top layer? Should I get spray primer then? Or just stick with brush paint for all three coats (primer, white, accent)?

>> No.1184734

>>1184705
I agree with this guy. I always do 2-4 layers of rust reformer and then whatever you want after that. I would buy some real nice spray paint so you dot get wierd drips and pooling like you would with house paint. Just follow the instructions on the can and do your best. Google techniques with spray paint for best results

Was thinking of doing this to my parents railing, but a chunk of ice left a huge couple inch dent in it. Also the vibration broke part of the lower stair. Plus the masomry is a bit of a mess anyway.

Any advice on how to use this wire attachment properly? It just keeps pushing the drill off the railing unless I apply immense pressure

I had rusty railings. I just removed rough rust with sand paper and cleaned the dust. Then I painted it twice with some anti-rust metal paint.
6 years have passed and nothing happened, no rust.

You should use this type of brushes for drills because they more stable. And you'd paint it with a brush because you'll lose a lot of paint.

That type is for large flat surfaces. You have none of those.

Get one where the bristles come out the side.. alternatively just continue to apply immense pressure.

muriatic acid works pretty well. I generally soak parts in 100% solution for about 15-20min. Be careful tho, it's a strong acid.

I found this one in a wheelbarrel in my dad's shed.

(Yeah. Gonna have to use some of the stuff in this thread on that wheelbarrel.)

If you're by a coast or have an Amazon account, get something called Corroseal. Paint it on, everywhere, two coats. Then just paint it with whatever you want to.

Yeah I'd image it wouldn't do great things to little bushings in a bike chain. In this case it would work just fine.

So I had a dremel in the basement with one of those sandpaper rotating heads so I gave it a try and bam it got that paint right off. Turns out these handrails aren't at rusty as I thought, just caked with layers of old paint and some cracks. The curly parts are the worst, the white areas less so, but it still took hours because that wire attachment didn't work as well as I'd hoped, and I only got half of one rail done

>> No.1185112

>>1185103
because you're using the wrong tool. you need an angle grinder with a wire brush head, not a drill.

THIS.

I once took the paint/ rust off this old guys rail on his front porch. Shit had like 5 layers of paint with rust in between them all. Had I not had an angle grinder and wire brush I would have lost so much labor scraping and applying naval jelly. Once you do that you'll be left with a few rusty pits and tarnish, hit it with some primer and hammered metal paint and it'll look brand fucking new.

>angle grinder
This is an excellent suggestion and I'll go a bit further and tell you to get a cheap one with not a lot of balls. A fast grinder with a lot of torque will bounce you all over the place. Dangerously.
Too many rpms and you'll end up kinda polishing the good existing paint.

Yeah I learned the hard way, all the online "how to sand and paint iron rails" sites said to use a drill with a wire attachment. I dont own an angle grinder so I'll just stick with what i have for now to save some money.

Since the dremel seems to be my best bet right now, I just bought one of those cheap 50 packs of sanding sleeves from amazon. The Curly metal has the worst rust while the white bars are less so. I'll get this project done somehow

Clean up the surface with sandpaper or wire-brush. And paint again. Do not forget to put some primer first, otherwise it will rust again.

I used this stuff from rustoleum that I applied with a cheap paintbrush on this vice I was working on yesterday. It stunk a bit but it works pretty well. I used a wire brush to clean away the rust.
