Question:

Spray Paint Aluminium Durable. Matte. Finish?

Hi guys. I was just wondering if you can give me some tips or information on what you know about painting on metal. The metal that is of concern is aluminium and I would like to put a stencil over this aluminium and just blast it with a can of krylon. Of course...this aluminium piece is actually part of the housing for my cell phone so doing it like this would probably not be right and the paint would probably wear out. I am mainly interested in finding out what kind of paint to use, what tools i need, and how to achieve an extremely! durable! matte finish because this phone is thrown around and going in and out of my pocket the paint will have to withstand getting rubbed down everyday by my pockets.That was a very long question, thanks for bearing with me and thanks in advance for those who provided me with an answer/thought. THANKS!

Answer:

Krylon is a very tough metal medium and the newer product they have at wal-mart in the paint section is fantastic. I don't know about rustoleum, other than another brand, but you could use a coat of polyutherine matte varnish. You can get this at wal-mart in the paint section or a hardware store. It will seal anything.

Spray paint, often Enamel, is pretty tough by itself, but I see your concern about it abrading in your pocket or by continuous use. There's a couple of things you can do to help with the wear and tear. Firstly, painting on Aluminum is great. You'll have no adhesion problems with the paint, so long as the aluminum is not polished (mirror finished) If it is, you need to scratch it a bit in order to allow the paint something to grab on to. You can use the same stencil you will eventually paint with to apply an etching solution (Etch I-M) so you don't mess up the finish on other parts of the phone. Or you can sand it with 0000 steel wool (that's 4-aught steel wool...), which is really really fine sanding. If the aluminum is 'sanded' or 'brushed' then you're probably good to go, just make sure that there is not a clear coat on the aluminum. If there is, then do the etching or sanding to it as well to get that clear coat off. You want to paint directly onto the aluminum. Once you spray your stencil with the paint of your choice over the etched or prepared surface, you should have a very durable finish. However, since you want it to be uniformly Matt, I'd say that you should find a good, high quality Matt spray varnish or topcoat. Lacquer is good (Varathane, Deft) and durable, and importantly, youcan always throw on another clear coat if the wear and tear is getting to the design. One thing: DON'T RUSH THE PAINTING! Allow enough time for each coat to dry completely, and once finished, let the final clear coats dry absolutely perfectly before handling the phone too roughly. Do some of this and your phone will look great. hope that helped...
