Exterior Mural Materials?

[Jeffrey Cook]

Hi All~

I’m being tasked with creating a series of exterior/building mounted paintings that need to be durable due to sun exposure and rain. I’ll be working on six 4×8 (plywood?) panels, but what panel material would someone recommend?    I’ll likely use exterior house grade paint, but then want a sealer that has sun fade protection, and graffiti -cleanable is a plus. Suggestions welcomed~

HI All

I’m going with a marine grade plywood, exterior house paint, and an exterior oil sealer from Germany called Osmo which has UV protection. I missed the scenic class on murals so will hope to catch that show next!

So sorry I missed this post earlier– I’d highly recommend a product called Alumacore- it’s thin sheets of aluminum clad around a corrugated plastic core. It’s lightweight (about 30lbs per panel), and entirely weatherproof and waterproof. The surface is smooth and great for painting, and just requires a light scuff with a scotchbrite and a layer of a good adhesion primer to make the surface ready for your mural.

The panels can be screwed directly to the wall or affixed to a simple aluminum frame. They’re a standard sign-making substrate and available at any sign supply store. Look for Aluminum Composite Panels, or ACP. There’s a lot of brands out there at different pricepoints.

My favorite UV protection sealer is MOdern Masters Masterclear Supreme, and Worlds Best Anti-Graffiti Coating is a wax-based sacrifical anti-graffiti coating that’s non-toxic and easy to apply.

Thanks Lili for your advice on this! I am pretty much completed with this job but I think there is another in the near future so I will learn from your information next time.
