When the color film loses adhesion to the surface, it causes peeling.
Causes
- Moisture penetration into the surface
- Poor surface preparation before painting, with dust and stains
- Painting on a wet surface
- High humidity environment or rain during painting, or rain shortly after painting is completed
- Using low-quality paint with a very low amount of adhesive (glue or Binder)

Solutions
- Prepare the surface by scraping off all the blistered paint with a scraper, sanding with sandpaper, and cleaning the surface to be free from dust or dirt.
- In areas with high moisture (accumulated moisture not exceeding 35%, temporary moisture not exceeding 40%), it is recommended to let the surface dry completely, then apply a primer once and allow it to dry for 6-8 hours. After that, apply a coat of high-quality multipurpose primer, Beger Pro Quick Primer B-1900, once.
- Topcoat with high-quality acrylic paint, such as Beger Cool, in 2 coats, allowing at least 2-3 hours to dry between coats.
