ᐅ Putty Technique Fades – Is This a Defect?

Hello building experts!

I am hoping to get advice from a professional or specialist familiar with painting or plastering techniques.

At the end of last year, we renovated our bathroom and had the walls finished using Pandomo wall technique. However, only about five months later, when removing the mirror by chance, we noticed the wall finish has faded and also lost the “warmth” of the color (see photos).

Can anyone with experience say whether fading of this kind of plaster finish is normal, especially after such a short time, and whether the degree of fading shown in the photos would justify reporting it as a defect?

We are quite disappointed and concerned that the finish might continue to fade. You could repaint a regular painted wall, but with this technique, no corrections seem possible.

Thank you in advance for your replies :-)

You are quite disappointed by something you discovered by chance? Maybe it doesn’t necessarily have to look different from the rest of the wall, and what’s behind the mirror is actually the "flaw"?

I don’t see many options to address this. Every wall fades when exposed to sunlight.

What lastdrop says is totally normal. Every paint fades over time.

Color pigments fade. This is a chemical process. Even if you have impregnated the surface with oil, as stated on the datasheet, it will still happen.

Thank you for your responses!
From my perspective, it is still frustrating and also hard to understand, as this fading occurred after only 5 months. I had also assumed that because putty techniques (made from plastic/cement) are not painted over, there would be greater color durability compared to fully painted walls from the start. :-(

I find this unacceptable. If a mineral ochre or a cheap and effective iron oxide had been used, this wouldn’t have happened. In all the smoothing techniques I have done since, I have never seen such a change. I would most likely attribute the issue to the possibility that a standard color shade offered by the manufacturer was not used, but instead a custom shade made from different pigments. Fading of yellow is as unnecessary as a goiter, unless it is Indian yellow. There are plenty of lime-resistant and color-stable options available.
