š How to Use Nail Files, Blocks & Buffers
Partager
Preparing the natural nail correctly is one of the most important steps in achieving long-lasting and flawless results in any nail service ā whether itās gel polish, builder gel, acrylic, acrygel or any hybrid system.
Professional nail preparation is not about filing aggressively, but about understanding which tool to use and why.
Many beginners over-buff the nail, making it too smooth and shiny. While this may look clean, it actually compromises adhesion and leads to premature lift, peeling or separation. The right grit and technique ensures the product bonds properly to the natural nail without causing damage, thinning or discomfort.
In this guide, you'll learn the correct use of nail files, buffers and blocks, including what NOT to do, how to avoid common mistakes, and what creates the ideal surface for product adhesion.
š What Each Tool Is Used For
| Tool | Purpose | Warning |
|---|---|---|
| Nail File (180/180 grit) | Removes natural shine and prepares the surface | Best choice for natural nails |
| Buffer | Smooths surface after product application | ā Not recommended for natural nail prep |
| Block | Blends product lines, refines shape and leveling | ā Never use on bare natural nail |
š« Common Mistake: Over-Polishing the Natural Nail
It may be tempting to use a buffer or block to create a smooth surface before applying product, but this leads to the mirror effect ā a shiny surface where product cannot grip.
When the nail becomes too smooth, the adhesion layer disappears, causing:
lifting at the cuticle
premature peeling
product detachment
weak durability
This is one of the most common reasons salon work fails ā and the good news? Itās easy to avoid.
āļø Correct Technique: Using a 180/180 Grit File
To properly prepare the natural nail:
Hold the file parallel to the nail surface ā never flat against it.
Gently remove only the natural shine.
Avoid filing in one direction only; use short, controlled movements.
Do not apply pressure ā the natural nail should never be thinned.
A properly prepared nail surface should look matte, not scratched, damaged or shiny.
This creates the perfect foundation to support adhesion promoters, primers and the product system you apply next.
šÆ Professional Tip
If you see dust sticking evenly across the nail after filing, it means the surface has been prepared correctly.
If the nail still reflects light, continue gently filing until the shine is removed ā but stop before removing layers.
š§¼ After Filing ā What Comes Next?
Once the nail is prepared with a 180/180 file:
āļø Remove dust
āļø Cleanse with a professional nail prep
āļø Apply primer if required
āļø Apply your chosen system
Skipping these steps affects adhesion as much as incorrect filing.
š¬ Closing Statement
Correct nail preparation is the foundation of long-lasting salon-quality results. Choosing the right tool at the right moment protects the natural nail, improves product adhesion and reduces service time ā especially during infills or maintenance.
Mastering this basic but essential skill will elevate your work immediately, whether you're a beginner or an advanced professional.
