When a template leaves a jagged border or a faint line that fades after a day, you’re seeing the most visible symptoms. Uneven paint spread, crooked edges, or a sudden lift of the design are all red flags that the template hasn’t adhered correctly. Recognizing these signs early prevents the need to start over and saves time and material.
Three primary culprits drive these issues. First, improper surface prep: a dull or oily base lets the template slip. Second, mismatched template size—choosing a square template for a round nail or vice‑versa forces distortion. Third, inadequate sealing; if the top coat is applied too thickly or too thin, the design can crack or lift. Identifying the exact cause is the first step toward a flawless finish.
