How to Thin Out Nail Polish

How To Thin Out Nail Polish

You want to prolong the shelf life of your laptop battery and your fancy red wines, and when it comes to nail polish, you can do the same thing. Now that I've already shared with you some easy ways to keep your polish around a little longer, I've got some tips for declumping, just in case your polish has lost some of its former luster.

The best ways to declump:

  • First try turning the bottle upside down to help distribute color that may have settled on the bottom. Gently roll between your palms to mix. This also warms the polish, which can help with spreadability.
  • If that doesn't work, try nail polish thinner. Just add a few drops of OPI Thinner ($8.50) or Nail Tek Slovent Renewer ($5.50) and shake gently.

To see the rest of my tips,


  • If you don't have thinner try adding a few drops of acetone nail polish remover. Only do this if you are planning on tossing the bottle soon, as the high water content and ingredients in remover can cause the polish to separate in the bottle, affecting the wearability of the polish.
  • Face the reality that all nail polish will clump eventually. One thing to keep in the back of your mind: Dark shades tend to become thicker faster because they are more heavily pigmented.

Nail polish companies that sell nail polish thinners give you just a little bottle of it for a big price. Instead, go to your hardware store and buy a small tin (500 ml or 2 cups) of lacquer thinner in the paint dept. for about 5 bucks. Take the cap off and dip a narrow straw in the tin, then cover the top of the straw with your thumb to hold the fluid to drop into a smaller glass bottle for storage and easier use. Use same method with straw to drop thinner into nail polish bottles. Avoid contact with skin. SMARTCOOKIE

i once used polish remover on my lovely pink halogram polish - and it complitely ruined it :( i almost cried, as the polish was extremely hard to get. and i can't find it anymore, it was an import. the halogram bits just disolved and the colour changed. it looked crap and i had to toss the bottle. it makes me want to cry everytime i think about it. i was beautiful. i should really check into those thinners... never heard of them before.

Also: DON'T SHAKE THE BOTTLE! This is so important and I always see so many people, like my friends, doing it! When you shake the bottle (rather than roll it gently between your palms as Bella suggested) it creates bubbles in the polish and only makes the polish go on bumpier, and clumpier rather than smoother. :)

My Chanel polish which I kept around for 5 years, I just trashed it a week ago. Even 2 weeks ago, it applied nicely on my nails than a new bottle of OPI - definitely worth spending money, not mentioning the beautiful color.
