Will the finish yellow or fade under strong sunlight?

Any surface ages under UV, but the risk is manageable. For Gulf and tropical projects we use UV-stabilised topcoats and UV-cured panels, and we advise against pure white high-gloss in rooms with strong direct sun, where warmer or matt tones age more gracefully. Curtains, blinds or UV-filtering window film on west-facing glazing extend the life of any finish considerably.
