Why Does Factory Paint Bubble?

[SanBethany]

Reasons for paint bubbling include: 1. Poor paint quality: This issue often occurs at roadside shops, which typically offer very low prices for paint jobs and use low-quality paints. 2. Unrigorous construction conditions and processes: Paint application requires high standards in terms of conditions and techniques. The surface must be completely free of moisture before painting; the filler (putty) applied during the initial surface preparation must be thoroughly dried in a dry environment before entering the paint booth; the air lines connected to the spray guns must remain completely dry, with no moisture allowed. These factors are significant causes of paint bubbling. 3. Excessive paint thickness: Lack of attention during the painting process or the limited skills of the workers can often result in the paint being applied too thickly, leading to sagging beneath the paint film.
