painting a aluminum shop sign

admin

So I'm building a shop sign. And I'm wondering if it can be painted like steel. I heard it works well if you use primer and a oil based paint and let it dry ?  It  will be mounted inside my shop/garage so it will be away from the weather. I mostly work with steel so this is something different to do. Thanks for your help .Millermatic 211 with mvp plugs miller titanium series welding helmetstihl chain saws 8 ft welding table
Reply:You need an etching primer and or a light media blasting then a coat of epoxy before paint can be applied... check with a body shop supply retailer, they may have specifically for painting aluminum... i would check into powder coating.....much more durable... hope this helps...Lincoln pro mig 180Lincoln Square Wave Tig 300/wp 20/home built water cooler Victor, Purox, Harris, O/A welding/cutting setupsVintage Craftsman drill pressVintage Craftsman/Atlas 12"x 36'' lathe7''x 12'' w/c band saw Everlast 140 st
Reply:self-etching primer and what ever paint you want, satin or flat finishes work best for signs, look at the signs that are up and you will see what I'm saying, spaying is best also
Reply:stihl91Painting for your purpose is close to obsolete.Powder Coat is the new paint.I switched to P/C with this price comparison.The client wanted his, just constructed industrialtable base painted, Corvette - Yellow.  The primer, reducer, and paint costs $110.00 in '94.Labor: then came proper primer/paint mixing, spray sequence technique, plus all of the prep.Accepted by the client, I found a yellow in P/C.Metal prep. [blasted], and perfect coating for $90.00.Powder Coating is available almost everywhere.Look under Coatings in your Yellow Pages.OpusLast edited by OPUS FERRO; 12-06-2012 at 01:05 AM.
