There are many types of nail files on the market to suit each type of nail or individual nails techniques. Understanding these types of files helps us easily choose the right type of file, avoiding breakage and corrosion of the real nail layer, causing thin and weak nails. At Mornington Spa, all technicians have understood the basic knowledge and reasons why they choose the safest, highest quality products for their customers.


1. Specifications of different types of files:

The numbers on the file are what nail technicians need to pay attention to when using the file on customers. That is the grit index - representing the roughness level of the file. Grit is the density of abrasive particles per inch; the greater the number of particles, the smoother the file surface. For example, a 250 grit file will be smoother than a 100 grit file.

Depending on the grit level, the uses of nail files will be different:

 + 80 - 100 grit: this is the roughest type of file, with a large rough surface, only used for filing false nails or filing acrylic nails.

 + 150 - 180 grit: is a regular nail file, used for natural nails.

 + 240 - 280 grit: is a fine file, used to smoothen nails, clean cuticles or for people with thin, brittle nails.

 + 500 grit: this is a file with a very smooth surface, used to polish the nail surface.

2. Some common types of files:

Basically, there are many types of nail files, with different shapes depending on the purpose of use.

+ Large coarse file 80/80: this is a low grit file, meaning its surface is very rough, only used for filing false nails, acrylic and the inside of press-on nails before applying.

+ Buffer file 100/180: it can be shaped like a regular file or it can be rectangular in shape, with a lot of thickness. Buffer is often used to smooth the nail surface after removing powder, removing gel or used to polish nails before applying gel or applying false nails.

+ 150/150 thick file: this is a very rough file, often used to file acrylic or gel nails, or file to break the surface of gel nail polish or acrylic nails to help the nail removal process faster.

+ 180/240 styling sanding file: this is the type of nail file most used by nail technicians. It is a thin, 2-sided sanding file, used to shape nails such as square nails, oval nails, almond nails...

+ 1000 fine file: with such high grit, you will see that the sandpaper surface is quite smooth, used to smooth the nail surface after removing products.

+ Nail polishing file: the use of this type of file will make the nail surface naturally shiny, used to polish natural nails, or polish the surface of acrylic nails to make them more beautiful. Normally, a polishing file will have many different sides, both a smoothing side and a nail polishing side.


At Mornington Spa, we choose high-quality files from the American company CND - a leading company in the nail care industry in the world.

KOALA BUFFER smooth float with 240/1200 grits, creating absolute smoothness for real foundations, even weak, brittle nails. Designed with a soft foam cushion, customers will not worry about their nails being damaged or painful when used.

We need to clearly understand the parameters of nail files as well as use them for their correct purpose to achieve the highest efficiency in the nail process. Remember to avoid using nail files with too much roughness to file the actual nail shape, because it is easy to damage the nail, hurt the customer's hand, and for customers with thin nails, it can also cause nail breakage and pops immediately after filing. Hope this article helps you understand the different types of files.
