In recent years, the number of domestic auto repair and maintenance enterprises has been steadily increasing due to the growing popularity of small cars. As a result, automotive refinishing paints, spray guns, baking equipment, and related technologies have gained significant attention from industry professionals. However, many repair shops still lack a systematic and professional approach when it comes to paint spraying and baking processes. There are numerous misconceptions among technicians, which can negatively impact the quality of repairs. This article highlights six common misunderstandings in the painting process.
1. **Workshop Facility Planning Mistakes**
- Poor layout leads to interference between different workflow stages.
- Inadequate planning of workshop facilities can compromise the overall quality of repairs.
2. **Manual Color Matching Errors**
- Accurate color identification is crucial. Technicians should compare the color on a palette under standard lighting to determine the main hue, brightness, and saturation.
- Proper selection of colorants is essential. The type, variety, thinners, and additives must be matched correctly.
- A small amount of test mixing should be done first to achieve accurate color ratios before mass production, reducing waste.
- Mixing procedures should follow a clear order—start with light colors and gradually add darker ones, ensuring thorough blending.
- When adding auxiliary materials, precise proportions and timely mixing are necessary for uniform results.
3. **Insufficient Preparation Before Painting**
- Inadequate surface preparation can lead to poor adhesion and long-term damage.
- Improper use of putty or incorrect sanding techniques can cause uneven surfaces and affect final appearance.
4. **Incorrect Use of Spray Guns**
- Many technicians lack proper training in spray gun operation, leading to issues like uneven coverage, overspray, or improper overlap.
- Correct technique, including speed, angle, and pressure, is essential for achieving a smooth finish.
5. **Poor Topcoat Application Process**
- A gritty surface may appear after repairs due to improper sanding or mixing.
- Color differences can occur when repainting an entire panel if the correct shade is not matched.
- Gloss inconsistency is common during spot repairs if the right materials and techniques are not used.
- An incorrect spray sequence can lead to visible lines or uneven coverage.
6. **Neglect of Baking Room Maintenance**
- Failure to maintain the baking room properly can lead to poor drying conditions, resulting in defects such as cracking, peeling, or uneven finish.
