Clumpy Gel & Hard Brushes

Why Does Gel Polish Go Clumpy and Brushes Go Hard?

At Bloss Gel, we understand how frustrating it can be when your gel polish becomes clumpy or your brushes go hard. These issues can make application difficult and affect the quality of your manicure. Since gel polish is highly sensitive to light and environmental factors, knowing how to care for it properly can help prevent these problems.

The Role of UV Light

Gel polish is designed to cure under UV or LED light, giving you a strong, long-lasting finish. However, exposure to UV light—whether from your curing lamp or natural sunlight—can cause polish to thicken, clump, or even harden in the bottle. If your brush is exposed to UV light while applying polish, it can also begin to stiffen, making it difficult to use.

Other Factors That Cause Clumpy Polish and Hard Brushes

While UV exposure is a major factor, other issues can also contribute:

  • Leaving Bottles Open Too Long – Air exposure can cause gel polish to become thicker and more difficult to apply.

  • Storing in Warm or Sunny Areas – Heat causes gel polish to change consistency.

  • Using Contaminated Brushes – If dust, lint, or old product builds up on your brush, it can lead to clumping and hardening.

How to Prevent Clumpy Polish and Hard Brushes

To keep your gel polish and brushes in top condition, follow these simple tips:

  • Work Away from UV Light – Always apply polish in a shaded area, away from direct sunlight and your UV/LED lamp.

  • Close Bottles When Not in Use – Even brief exposure to air and light can cause thickening.

  • Store Properly – Keep gel polish in a cool, dark place to maintain its consistency.

  • Use Thin, Even Layers – Thick coats of polish are harder to cure evenly and may lead to clumps.
