Every IXXI is suitable for outdoor hanging. The cards are made of high-quality synthetic matte material called Synaps. This material is water-resistant, tear-resistant, and does not warp.
As with any photo product, it's possible for the print to fade over time when exposed to UV light frequently. The speed at which an IXXI fades can depend on several factors, with the most significant factor being the amount of direct sunlight it receives. Darker colors generally fade faster because they attract more sunlight.
We recommend choosing a location where your IXXI is as sheltered as possible from sun and rain, securely fastening it, and protecting it from the rainy season. You can read more about this in this article.
For the proper attachment, you can choose the Outdoor kit. This kit includes 5 screws and 5 plugs. You alternate between attaching a Powerstrip and a screw. In this video, you can see exactly how it works.
