BIAB vs. Fiber Overlay Gel: What Is the Difference?
Two popular options in the nail industry are BIAB (Builder Gels) and Fiber Overlay Gels. While both are designed to strengthen and protect the natural nail, they offer different textures, benefits and application possibilities.
The main difference between BIAB and Fiber Overlay Gel is their consistency and formulation.
Builder Gel has a lower viscosity and is ideal for easy application, self-leveling and creating natural nail overlays or extensions. It is a versatile option for brands looking for a smooth and easy-to-use builder gel.
Fiber Overlay Gel, on the other hand, has a thicker consistency and contains synthetic fibres. This makes it particularly suitable for strengthening the natural nail and filling ridges or uneven areas.
Both products offer long-lasting wear and are designed to support a beautiful and durable manicure.
At Interfilling, we offer professional Builder Gels and Fiber Overlay Gels for brands looking for high-quality nail products.

Builder Gel vs. Traditional Gel
Traditional gel polish is primarily designed to provide colour and a durable finish. Builder gel is formulated to provide additional structure and support.
Key differences include:
- Higher viscosity: Builder gel is thicker and more suitable for building structure.
- Added strength: Helps reinforce and strengthen the natural nail.
- Building capability: Can be used to create an apex and add shape.
- Versatile application: Suitable for overlays, strengthening and certain extension techniques.
- Professional finish: Designed for salon-quality nail applications.
