Why is it essential to file a crack before applying acrylic?

  1. To improve the adhesive properties

  2. To make the nail look attractive

  3. To prevent future cracks from occurring

  4. To ensure the acrylic dries faster

The correct answer is: To improve the adhesive properties

Filing a crack before applying acrylic is essential primarily for improving the adhesive properties. When a crack is present on the nail, the surface may be uneven or damaged, which can hinder the adherence of the acrylic to the natural nail. By filing down the crack, you create a smoother and more uniform surface that allows the acrylic to bond effectively. This strong bond is crucial for the longevity and durability of the acrylic application, as it helps to prevent further chipping or lifting of the acrylic overlay. While making the nail look attractive is important, it is not the primary reason for filing a crack. The aesthetic appeal is a secondary benefit resulting from ensuring proper application techniques. Preventing future cracks is also not directly related to the immediate action of filing; rather, it focuses on the integrity of the nail over time. Lastly, the drying speed of the acrylic is influenced by other factors, such as the type of acrylic used and environmental conditions, rather than the filing process. Thus, filing serves a critical role in achieving a successful and long-lasting acrylic application through enhanced adhesion.
