An emery board gets smooth over time because its abrasive surface has been worn away, usually due to repeated use. Every time you use an emery board to file your nails, the rough particles on the board remove a little bit of nail material. Over time, the particles get clogged with dust, flatten, or fall off the board is excess material.
Once an emery board is smooth, is it no longer a useful tool to file your nails; it should be thrown out and replaced with a new one.
Do Emery Boards Wear Out?
Yes, emery boards are designed to wear down as you use them.
Unlike a glass or metal nail file, an emery board has abrasive material attached to a cardboard or foam base. As you use it, the surface becomes less rough over time.
You may notice things like:
- Filing takes longer than it used to
- The board slides across the nail without doing anything to shape it
- Some sections feel smoother than others
- The abrasive coating looks patchy
- The edges have started to bend, split, or peel
These are the signs that the emery board is no longer useful for filing your nails down.
Can Nail Dust Make an Emery Board Feel Smooth?
Yes, nail dust can collect between the abrasive particles, making the surface less effective.
You may be able to remove some loose dust by gently tapping the board over a bin, or brushing it with a clean, dry brush. This will not, however, restore the abrasive material that has already worn away.
Emery boards are porous, and are therefore not as easy to wash or clean compared to glass or metal nail files.
Can You Make a Smooth Board Rough Again?
Not usually, no.
Once the surface has worn down, there is no good way to restore it. This is the point at which your best bet is to throw it away and replace it.
Does Using Too Much Pressure Wear It Out Faster?
Pressing down very hard with the emery board may break down the surface more quickly and make your filing less controlled.
You only need to use gentle, steady pressure and let the abrasive surface do most of the work, rather than brute force.
You can use a grit that suits your nails to make filing easier. A file that is too fine can feel slow to use, whilst a very coarse board can remove more nail than you wanted.
How Long Should an Emery Board Last?
There is no hard-and-fast, fixed lifespan that an emery board should last. It largely depends on factors such as:
- How often you use it
- How many nails you file
- How much pressure you apply
- The quality of the board
- The grit of the surface
- Whether it’s used on natural, artificial, or toenails
Check how well your emery board works; if it’s smooth and doesn’t file your nails effectively, it’s probably time for a new one.
Should You Use Both Sides of an Emery Board?
Provided both sides are designed for filing and have an abrasive surface, then yes.
Some emery boards have abrasive material on both sides, and some have a finer and a coarser side. You can move to using a more intact section or turn the board over if one part starts to wear away.
How Can You Help an Emery Board Last Longer?
To keep your file in better condition, you can:
- Use gentle pressure
- Use the full surface, rather than one small area
- Tap away loose nail dust after you use it
- Keep it dry
- Store it in a protective case
- Avoid bending the board
Proper storage won’t prevent the surface wearing down with use; this is normal. Looking after your emery board, however, can prevent unnecessary damage.
Final Thoughts
Emery boards go smooth over time as they are used and the abrasive surface is worn away and clogged with dust. This is a completely normal process, although you may be able to remove a small amount of the nail dust. A surface that has worn away with use cannot usually be restored.
Once your emery board no longer shapes your nail well, it’s time to throw it out and replace it with a fresh one!
