- Moisture and UV radiation: condensation and rain, together with sunlight, put strain on the coating and can cause the color pigments to fade.
- Pollutants and acid rain: they too attack facade coatings and can change facade color shades.
- Soiling level: car or industrial exhaust fumes as well as algal or fungal growth on damp facade elements soil the facade surface and darken the color shades.
