Does decoupage decay in the daylight?

A worry customers have about my work is that the decoupaged surface might fade in the sunlight if place on a windowsill or in bright room for example. I am glad to report that I have not encountered any complaints regarding fading from customers to date since I began selling them as finished products in 2016, which is great news! I also have pieces dotted around my own home and gallery have not witnessed any fading myself. Provided that they are kept indoors modern window glass blocks enough U.V. light that fading should not be factor.

As my intention is that my work is also suitable to put outside as a garden feature, I try to use commercially printed papers (magazines, not newspapers) that are inherently fade resistant. I am working from observation, rather than having looked into this scientifically but it appears through trial and error that glossy published surfaces come with their own U.V. protection/a layer of protective varnish - perhaps someone out there can tell me exactly how they are produced?

To ensure my work stays bright and colourful I handpaint most of the surface of the work and use only small amounts of carefully chosen decoupage, which guards against potential issues with fading that might compromise the look of a piece over time with exposure to the sun. I also handpaint my own papers so that I can achieve a decoupaged look without risking any fading of the paper colour.

I have also tried experimenting with various types of U.V. varnish with a greater and lesser degrees of success. U.V. protective varnishes do what they say on the tin, but create a plastic film that tends to peel off from the sculpture surface so is not good for waterproofing and will not take other sealants applied on top.

If you are still worried that your sculpture might fade in the light, my best piece of advice is just to have some sympathy with the materials - we are all advised to use factor 50 in the mid-day sun so maybe it's best not to show off your paper art in the direct light of the conservatory and brighten up a dull room with it instead!
