1. Probable Cause / Reason:
• Disintegration of the paint binder due to exposure to weathering or ultraviolet (UV) light.
• Breakdown occurs over time, causing the paint film to lose its integrity.
• The chemical structure of the binder weakens, leading to surface degradation.
• Chalking rates can differ depending on pigment concentration and binder selection.
2. Correction:
• Apply a high-quality topcoat with UV resistance and chalking prevention properties.
• Select coatings with durable binders that resist environmental stress.
• Ensure proper surface preparation before re-coating.
• Opt for paints formulated to withstand prolonged exposure to sunlight and weathering.
3. Corrective Action:
• Remove the chalky residue by cleaning the surface thoroughly.
• Apply a protective, UV-resistant coating to prevent further degradation.
• Regularly inspect and maintain the surface to monitor for early signs of chalking.
