What is the main purpose of using a buffer block in nail application?

1. To apply nail oil

2. To smooth the surface

3. To clean the nails

4. To soak the nails

The correct answer is: To smooth the surface

The main purpose of using a buffer block in nail application is to smooth the surface of the nails. Buffing helps to create a polished and even finish, eliminating any ridges or imperfections in the nail surface. This is an essential step, especially when preparing the nails for nail enhancements or applying nail polish, as a smooth surface allows for better adhesion and a more aesthetically pleasing result. When a buffer block is used, it typically contains different grits that gradually reduce in coarseness, allowing the nail technician to refine the surface progressively. The benefit of having a smooth, even surface is also that it can enhance the overall appearance of natural nails and assist in the longevity of applied nail products. The other options provided—applying nail oil, cleaning the nails, and soaking the nails—do not relate to the primary function of buffer blocks. While those actions are part of nail care and maintenance, they serve different roles in the overall nail treatment process.
