Cleaning Steel Prior to Painting?
When I put out the flag today I noticed that the steel wall bracket is
rusting, in spite of this being Arizona, where rust is forbidden ;-) Do I remember correctly that cleaning steel in a mild acid solution is the best treatment to remove the rust, then prime and paint? ...Jim Thompson -- | James E.Thompson, P.E. | mens | | Analog Innovations, Inc. | et | | Analog/Mixed-Signal ASIC's and Discrete Systems | manus | | Phoenix, Arizona Voice480)460-2350 | | | E-mail Address at Website Fax480)460-2142 | Brass Rat | | http://www.analog-innovations.com | 1962 | America: Land of the Free, Because of the Brave |

You want phosphoric acid, IIRC. It's the stuff in Naval Jelly, at any rate. It cleans the rust and leaves a mild, paintable, anti-corrosion film behind. -- Tim Wescott Wescott Design Services http://www.wescottdesign.com Do you need to implement control loops in software?

I'd use a flap wheel or sanding disk to remove 90% of the crap. Maybe a slosh over with phosphoric acid or one of the off-the-shelf versions, then a coat of "Hammerite" works wonders. Limited colors, but it's pretty tough. Barry |

Follow the instructions on the can. It will take at least overnight to dry. If it has reached the flaking point mechanical removal of the rust is advised!

Then Murtic acid for heavy jobs BTW, use rustolium and their primer. If not I really like the Painters Touch paint, really good UV protection. Cheers |

I noticed that the steel wall bracket is rusting, in spite of this being Arizona, where rust is forbidden ;-) Do I remember correctly that cleaning steel in a mild acid solution is the best treatment to remove the rust, then prime and paint? I'd go with John's advice. Brush off any coarse stuff with a wire brush, then a fresh coat of your favorite color Rustoleum. Ace has some good stuff as well. Initially I thought that there is no free lunch when it comes to rust but my wife convinced me. She regularly spray-paints rusted lawn chairs and afterwards the paint lasts years. And this is Cahleefohniah where is does rain and freeze and all that. -- Regards, Joerg http://www.analogconsultants.com |

Wife picked up 2 for less than $2 ea. Otherwise remove the rust mechanically, finish up wiht some naval jelly, prime and paint. Not worth the two bucks to me. When mine doesnt have a flag in it it holds a support for hanging flower pots |
