The Key Role of Nail Surface Treatment in Nail Care

You might not realize it, but nail surface treatment is the cornerstone of a perfect manicure. It sets the stage for the entire nail - care process, directly influencing the final result. A proper pre - treatment can enhance the adhesion of nail polish, prevent chipping, and ensure a smooth and long - lasting finish. In the nail care industry, this pre - treatment step is so crucial that it can make or break a manicure.

Technical Logic of Three - grade Grit Design

Your double - sided multi - functional nail file comes with three grades of grit, each with a specific purpose. The coarse grit is designed for removing cuticles and rough edges. It can be used about 20 - 30 times before it starts to lose its effectiveness. This grit is ideal for the initial stage of nail pre - treatment, where you need to quickly shape the nail and get rid of any unwanted rough parts.

The medium grit is for nail shaping. It helps you refine the shape of the nail, whether you're going for a square, oval, or round shape. After using the coarse grit, the medium grit can smooth out the edges left by the previous step.

The fine grit is used for polishing. It gives the nail a shiny and smooth finish, making it ready for nail polish or other treatments. An information chart (a simple schematic diagram) can show you the correct order of using these three grades of grit, ensuring that you use each one at the right time for maximum efficiency.

Differentiated Grinding Strategies for Different Nail Materials

When it comes to different nail materials, you need different strategies. For natural nails, you should be more gentle. The coarse grit can be used sparingly, as over - filing can damage the natural nail. About 10 - 15 uses of the coarse grit are recommended for natural nails to avoid excessive thinning.

Acrylic nails are more durable. You can use the coarse grit more aggressively, but still, pay attention to not over - filing. The medium and fine grits can be used more frequently to achieve a smooth and shiny surface.

Gel nails require a different approach. The fine grit is often the most used, as gel nails are already smooth and mainly need a final polish. And for wearable nail tips, you can use all three grades of grit to customize the shape and finish according to your needs.

Common Mistakes in Nail Filing

Many people make mistakes when using nail files. Over - exerting pressure can lead to uneven filing and damage to the nail. Ignoring the replacement time of the file can also cause problems. For example, if you keep using a worn - out file, it won't file the nail effectively and may even cause scratches. Holding the file at the wrong angle can result in an uneven shape.

Scientific Methods to Judge File Replacement

There are several ways to judge if your nail file needs to be replaced. Visually, if you see that the grit is worn out or the surface is uneven, it's a sign that the file is nearing the end of its life. You can also keep track of the number of uses. As mentioned before, a coarse grit file has about 20 - 30 effective uses. Additionally, if you notice that the polishing effect is not as good as before, it's time to replace the file.

Practical Tips for Nail Filing

Controlling the force and frequency of filing can save you time and improve consistency. For example, using short, light strokes can give you more control and a more even finish. By following these tips, you can make each filing session more efficient and improve customer satisfaction if you're a professional nail technician.

It's worth noting that our nail files meet REACH/FDA certifications, ensuring their safety and quality. They are also designed with an EVA foam core and a non - slip PP handle, providing you with a comfortable and secure grip during use.
