The painted film has a bumpy texture with uneven appearance.
Causes
- Dust, powder, and dirt particles sticking to the paint film
- Using unclean brushes or rollers
- Color residue mixed in the paint without proper stirring before application
Solutions
- Allow the paint to dry completely, then sand the surface to a smooth finish. Clean the surface before repainting.
- Use clean brushes or rollers for application, ensuring the paint does not contain dried color residue mixed in. Stir well before use.
- If using paint that has been stored for a long time, use a drill mixer to blend it into a uniform consistency, ensuring no dried color particles are mixed in.
