Why should technicians avoid direct sunlight when painting?

Technicians should avoid direct sunlight when painting because exposure to direct sunlight can lead to improper curing and various defects in the paint job. When paint is applied in direct sunlight, it may dry too quickly, which can prevent the paint from leveling out properly and may cause issues such as bubbling or an uneven finish. Additionally, the rapid drying can lead to insufficient bonding between the paint and the substrate, compromising the overall durability and appearance of the paint.

Moreover, extreme temperatures can alter the chemical processes involved in paint curing, potentially resulting in issues such as a decrease in gloss, discoloration, or even peeling. Therefore, choosing a shaded area or a controlled environment for painting is essential to ensure that the application process adheres to the manufacturer's specifications and achieves the desired results in terms of finish and longevity.
