The evaluation of adhesion is a difficult point for many users who use the adhesIon Meter. Since the evaluation is done by visually sensing the peeling of the coating, there is inevitably a little fuzzy area when evaluating the adhesion level of the paint film. This article mainly uses pictures to evaluate the adhesion level in an intuitive way.
| Adhesion rating | Peeling degree | sample image |
| 5B | 0% - no flaking |  |
| 4B | less than 5% |  |
| 3B | 5%-15% |   |
| 2B | 15%-35% |   |
| 1B | 35%-65% |   |
| 0B | more than 65% |  |
