Why Does Gel Crack on Nails? | 5 Causes, Chemical Facts, and Solutions to Cracking Gel Nails
28 April 2025
Wondering why gel on nails_sometimes cracks, even when everything seems to be applied perfectly? In this comprehensive article, you will discover the 5 main causes of cracks in gel nails, including the chemical processes involved and solutions to prevent cracks.
Beautiful, strong gel nails are not only the result of craftsmanship, but also of the right materials and techniques.
In this comprehensive article, we provide clear answers and solutions.
Cause 1: Incorrect preparation of the natural nail (preventing cracks in gel nails)
What's happening?
The natural nail is covered with a microscopic _ of fat that protects it from drying out and damage. If this _ is not removed properly before applying the gel, the bonding can fail. This leads to air bubbles, lifting and eventually cracking of the gel nail.
Interesting fact:
The bonding takes place at a microscopic level. Primer and base coat penetrate the top _ of the nail and form a strong `glue bond`.
Solution:
- Gently matt the nail plate with a fine buffer.
- Degrease thoroughly with a dehydrator.
- Apply primer sparingly using the almost dry brush technique.
- Work hand by hand to prevent re-contamination.
Cause 2: Wrong choice of gel or base coat (causes of cracked gel nails)
What's happening?
Not every gel is suitable for every type of natural nail. The mechanical properties of the gel must match the flexibility and strength of the nail.
- A hard gel on a flexible nail breaks quickly.
- A soft gel on a long extension offers too little support.
Interesting fact:
Gel is made up of monomers and oligomers. The length and structure of these molecules determine whether the cured gel is hard and strong or flexible and springy.
Our Builder Gel from VERIN contains short chains, which provide a super strong, dense structure — ideal for longer nails.
Solution:
Match the material to the nail type:
- Flexible nails: use elastic gels such as Smart Gel.
- Strong, long nails: choose hard gels such as Builder Gel or Unique Gel.
- Always use a suitable base coat under the builder gel.
