Has anyone had any success with spray painting vinyl? I know manufacturers paint their windows at the factory, so I assume it must be possible DIY too. Reason I am interested in this is because I can find good quality white windows dirt cheap at a seconds store and if I can reuse these for my build, then more windows wont have to be made just to satisfy my wife's desire for colored windows! Plus I can save a lot of money to spend elsewhere. Thanks!

The different colors of vinyl windows from the manufacturer are different colors of vinyl, so the color goes all the way through the material. I'm not so sure any manufacturers are painting vinyl at the factory. Vinyl trim can be painted with latex, but it doesn't always do well and needs to be re-painted often depending on the conditions, climate, placement. I would think on a window, with all the different expansion and contraction rates of vinyl, glass, and latex paint, you're inviting a lot of issues.

I know a number of vinyl companies paint their windows. I saw one at the store yesterday. I peeled off some tape on the nailing flag and the flange was white underneath. I have also spoken to some companies that do paint their windows.

Just hoping their is some arousal can I can buy that people are happy with.

Interesting. What climate/region are you in?

I know that two major vinyl window companies in New England paint their windows, and we've used some of them with no issues. They also have a few "vinyl colors" like Beige, but colors like dark green are painted on. They have spent years perfecting paint that won't peel off, since bonding paint with vinyl can be problematic. Painting them as a DIY - you should do some research and plan to use a bonding agent.

I'm in NY. I have done some research and come up empty handed unfortunately. I was hoping someone here had some insight.

You'll probably have better luck in a cooler climate like NY. But you also have freeze/thaw cycles to worry about, unless you're near the coast.

Being in the window business as well as icf's, it is very easy to paint a vinyl window. The company I buy from can paint them any color you like. I've done it myself. I used Krylon, it's made for vinyl. I would stay away from really dark colors unless you don't mind a repaint in the future. Eventually they will fade as do solid vinyl windows in brown and tan. I imagine with a log home your thinking of green. Here in upstate NY colors will fade but less so than in the south.
