The short answer to this question is the you can paint storefront windows frames. Most storefront systems are made out of anodized aluminum – you can read more about the anodizing process here – https://www.anodizing.org/page/what-is-anodizing. Painting anodized aluminum is pretty straightforward and no special process has to be followed other thank a heavy duty cleaning to remove atmospheric contamination, a bonding primer, and a good fade resistant exterior grade paint. For painted storefront mullions, a bit more investigation must take place to determine how to proceed. Some silicon and Kynar coatings present more challenges, but there are methods to paint over those coatings too. Very rarely, will a coating have to be completely removed in order to paint storefront windows. At Indiana Painting, we typically spray all of our primers and topcoats when painting storefronts Systems. This ensures a quality, factory like finish so your facility and keep that well cared for feeling!

Our go to products for storefronts are TSP Substitute for cleaning, 220 grit sandpaper for sanding, MultiSpec Primer for priming, and either Sherwin Williams Emerald Urethane Trim Enamel or PPG Breakthrough. If you have an extremely harsh environment, we would recommend a two part epoxy primer and a two part urethane topcoat for added durability.

The cost of the bonding primer and Breakthrough system will run you about $50 per linear foot of window on each side. So, if you have a storefront window that tis 50’ long and 8’ tall, the price would be around $2,500 per side (interior/exterior).
