What are gel basics?

Gel basics are the core products that form the structure of a gel manicure: the base layer that bonds to the nail, the builder or overlay that creates strength and shape, and the top layer that protects the colour and adds shine or a specific finish. A stable system of base, builder and top gel is essential for durability and client comfort.

Base gels / gel base coats

The gel base coat (or base gel) ensures adhesion between the natural nail and the subsequent gel layers. It helps prevent lifting and improves wear time. Some base gels are designed as:

• Standard base gel – thin, self-levelling base for gel polish systems.
• Rubber base – more flexible base gel that can absorb stress on natural nails.
• Strengthening base – slightly thicker base that can smooth irregularities and add strength.

Builder gels and overlay gels

Builder gels and overlay gels are used to create structure, apex and additional strength. They can be used over natural nails, tips or forms, depending on the system. Korean builder/overlay gels are often self-levelling for efficient salon work.

• Builder gel in a pot – typically used with a brush for overlays and sculpting.
• Builder gel in a bottle – easier application, ideal for salon speed and natural nail overlays.
• Soak-off builder gels – can be soaked off with remover (depending on manufacturer instructions).

Top gels / gel top coats

The top gel seals the design, protects the colour and defines the finish (high gloss, satin or matte). It is the last layer in the gel system and is crucial for scratch resistance and shine.

• No-wipe top gel – cures without a sticky dispersion layer; ideal for quick finishing and chrome.
• Wipe-off top gel – leaves a dispersion layer that must be cleansed after curing.
• Matte top gel – gives a velvety matte finish, also suitable for nail art effects.

How to combine gel basics in a service

1. Prepare the nail: file, shape and gently etch the surface according to your salon protocol.
2. Apply a thin base gel (standard, rubber or strengthening) and cure under a suitable UV/LED lamp.
3. Build structure with a builder or overlay gel, create apex and refine the shape, then cure.
4. Apply colour gel polish or work directly with a cover builder, depending on the system.
5. Seal with an appropriate top gel (no-wipe, gloss, matte) and cure fully.

FAQ – Gel basics for professionals

Do I need a specific base and top for each system?
For optimal performance, it is recommended to use the base and top gels from the same system or brand as the colour or builder gel, following the manufacturer’s curing times and instructions.

What is the difference between rubber base and builder gel?
A rubber base is a flexible base layer designed to improve adhesion and comfort on natural nails. A builder gel is used to create more structure, apex and thickness. Some products can function as both, but always follow the specific product guidelines.

Can I use these gels on natural nails and extensions?
Many base, builder and top gels are suitable for both natural nails and extensions, but this depends on the formulation. Always check the technical information for each product and work within its intended use.
