ageing

In the context of painting and coatings, "ageing" refers to the natural process by which paint, coatings, or surfaces deteriorate or change in appearance and performance over time due to exposure to environmental factors such as:

• UV radiation from sunlight
• Moisture (rain, humidity)
• Temperature fluctuations
• Pollution and chemicals
• Wear and tear

Ageing can result in visible effects such as fading, chalking, cracking, peeling, or loss of gloss. It can also affect the protective qualities of the coating, reducing its effectiveness in shielding the substrate (e.g., timber, metal, masonry) from damage.

In the painting industry, understanding ageing is important for selecting the right products, planning maintenance schedules, and ensuring long-term durability of finishes.
