Which type of file is specifically used to thin the enhancement before a fill or rebalance?

1. Coarse grit

2. Soft buffer

3. Edge file

4. Glass file

The correct answer is: Coarse grit

The coarse grit file is specifically used to thin the enhancement before a fill or rebalance due to its effective abrasive properties. When a client comes in for a fill or rebalance, the existing nail enhancement may have grown out and need to be refined to ensure that the new product adheres properly. Using a coarse grit file allows the nail technician to remove a significant amount of product effectively, preparing the surface for the new application without causing damage to the natural nail underneath. It creates a rougher surface that enhances the bond between the natural nail and the new product applied during the fill. This step is crucial for ensuring the longevity and appearance of the nail enhancement. The other types of files mentioned serve different purposes. A soft buffer, for instance, is typically used for finishing and smoothing out the surface of the nail after filing, while an edge file may be utilized for refining the shape rather than for thinning. A glass file is gentle and primarily employed for natural nails, helping to smooth edges without removing product. Each file has its specific use in the nail care process, which is why the coarse grit file is the optimal choice for thinning prior to a fill or rebalance.
